PRESIDENT Atlas Copco Road Construction Equipment

Dear reader, Since the acquisition by Atlas Copco in 2007, Dynapac and the Road Construction Equipment division are headquartered in Stockholm.

Being the capital of Sweden, Stockholm is an old, beautiful and clean city. In fact, Stockholm was recently awarded “European Green Capital of the Year 2010” by the European Commission. A strong focus and dedicated work by authorities, city councils and the inhabitants of Stockholm have jointly accomplished the nice environment we are enjoying today.

Also for Dynapac as a company, we are now strengthening our commitment to develop and deliver sustainable products and solutions. There is no doubt in my mind that our focus on sustainability is needed in order to help customers create lasting results and also to drive satisfaction. There is no contradiction between profit and sustainability. On the contrary there is a win-win situation where creating energy efficient, reliable products also will save time and money at the construction site.

So what does sustainability mean for Dynapac? I can summarize in three main points:

The Atlas Copco Group is this year strengthening its promise to be committed to sustainable productivity. Dynapac, being a part of the Group, shares this vision as we talk about ”The Sustainable Way.” The sustainable way is a promise to support our customers in creating lasting, sustainable results that pay off.

We do not take this lightly and we are turning every stone to see how we can best deliver sustainable productivity to all stakeholders.

In this issue of Dynapac News, you can read about the Dynapac Global Sustainability Day, which was organized at all Dynapac manufacturing units to create internal awareness and commitment to our sustainability work. You can also read about the big upcoming exhibition event this year, Bauma in Munich, and find out how our equipment can help increase uptime and lower inefficiencies and costs. I hope you share our vision for the sustainable way and find the magazine interesting. Enjoy the reading!

- We shall create long term value for our customers and other stakeholders; - We shall focus on quality in products and processes; - We shall take responsibility - environmental, social, ethical, and financial.

Dynapac in major Saudi infrastructure project

Building a railway throu Saudi Arabia looks to the future with mega investments in infrastructure. One spectacular project is the 2 000 kilometer railway system that will link the country’s ports and major cities. Dynapac soil compactors are already preparing the banks for a new high speed railway that will bring millions of pilgrims from Mecca to Medina.

ALL THE GULF Cooperation Countries (GCC) have decided to invest in a mutual railway network connection. In the first stage Saudi Arabia is building a local network railway to connect the country’s three largest ports, Jeddah Islamic Port in the west with Riyadh`s Dry Port and Dammam`s King Abdul Aziz Port in the east. A north-south railway system will link the northern mineral mines of Al Jalamid and Az Zabirah to the ore processing facilities in Ras Azur on the Arabian Gulf.

Better connections support business and growth National railway projects are ongoing in the other GCC member states surrounding the Gulf – Kuwait, Qatar, Bahrain, and the United Arab Emirates – with the mutual goal to connect the countries and to improve transportation of both cargo and passengers. Currently the connections between the countries mainly rely on road transport with trucks, or by ships or planes.

“There are several contractors on the 2 000 kilometers of railway track, both local and international, and we have sold equipment to most of them,” says Ihab El Dessouky, sales manager for Dynapac Road Construction Equipment in the Middle East and North Africa.

Through the desert on high speed rail The best deal so far, he says, is the sale of 200 12-ton soil compactors to The Saudi Arabian MASCO – Mohammad Ali Al Swailem Group. The construction company was invited to bid for the mega railway project and was awarded the contract to build the Haramain High Speed Railway. The railway is the first high speed rail in the Middle East. It will be a 320 kilometer-per-hour railway linking the cities of Mecca (Makkah) and Medina (Madinah) through Jeddah and Rabigh, as well as the International Airport in Jeddah. The 415 km long line will provide fast and safe transport for the millions of pilgrims visiting the Holy Cities. The high speed railway will offer an alternative to traffic congestion and serve as a highly effective public transport link between fast growing and economically active commercial centers.

Reliable equipment is a must “The whole railway project in Saudi Arabia is still in the initial phase so we expect more orders. We have done business with Al Swailem for a long time and have a good cooperation through our distributor Medco, Middle East Development Company,” Ihab El Dessouky says.

This is confirmed by the Executive President of MASCO Abdulrahman Mohammed Ali Al Swailem.

“We have been using Dynapac soil compactors for many years in various road construction projects. They have proved to be durable and reliable and to give a notably long service life,” he says, ”and the local distributor, Medco, has played an equally important role, as their commitment to provide good support and service has gained trust and respect.”

Medco has been a strategic partner in many large building projects in Saudi Arabia, supplying heavy construction equipment for more than 40 years.

Support and training closed the deal Building in a country like Saudi Arabia can be challenging. In summertime temperatures can reach 50 degrees Celsius, so it’s important that the hydraulics work well in extreme conditions.

Nearly half of the 2 000 kilometers of railway goes through desert areas with loose sand that gets into even the best of machines, which can create engine failures. Service has to be offered continuously and spare parts kept available through a mobile workshop that can solve problems on site.

“When choosing a supplier we look for quality and service life in combination with good value for the money,” Abdulrahman Mohammed Ali Al Swailem says, and he emphasizes that reliability, with good service both on site and in the workshop, is very important.

Know-how is priceless The training of operators and mechanics and the technical advice given are equally important for MASCO. Dynapac’s sales manager agrees that this is an important order winner.

“Dynapac is not only selling equipment. We are also taking care of our customers and use our experience in building and compaction to improve the competence and build the confidence of our customers,” Ihab El Dessouky says.

He explains how a lot of work is done by Dynapac’s experts together with the customers to find the best way to work on a particular site and under certain conditions.

ugh the desert

In summertime temperatures can reach 50 degrees Celsius and the hydraulics should work well in these conditions.

Almost 1 000 kilometers of railway goes through desert areas. Dust and sand can easily create engine failures.

“When choosing a supplier we look for quality and service life in combination with good value for the money.�

Abdulrahman Mohammed Ali Al Swailem

Executive President of MASCO

Energy efficient road construction

New method of laying asphalt at lower temperatures It has been discussed for many years, how to find a method, that makes it possible to lower the temperature of asphalt mix without affecting the quality in a negative way. The main gains with a lower asphalt temperature are less energy consumption, reduced emissions and a better working environment.

The main challenge is to maintain the low binder viscosity that comes as a result of the high temperature that traditional hot asphalt mix is produced at.

A slower ageing process

Several of the leading contractors have developed solutions which makes it possible to mix the aggregate and bitumen at 120-130 degrees instead of 150-180 degrees, and still get asphalt which is durable enough to be used on busy roads.

One example is NCC, who a few years ago, launched the NCC Green Asphalt.

“In 2008-2009, we laid almost 50 000 tonnes of NCC Green Asphalt on everything from minor urban roads to port facilities and European routes.

The analysis carried out on binder content, grain size distribution, Nils Ulmgren moisture content, Foto: Gösta Rising stiffness modulus, penetration, softening point and other key parameters all show at least equivalent quality to a conventional mix,” says Nils Ulmgren, development manager at NCC Roads.

“In addition, we can expect a longer asphalt life time because the reduced oxidation means that the binder is ageing more slowly.

Although we do not get exact answers until the pavements have been used a few years, everything indicates that the quality of low temperature asphalt equals the hot

asphalt. The concept seems very promising in terms of the environmental benefits that the lower temperature gives”.

Environmental benefits

Lowering the asphalt mix temperature by 30 degrees reduces the energy consumption by 20 percent. Also, the emissions curve fall sharply; carbon dioxide by 30 percent, nitrogen oxide by 70 percent and sulphur dioxide by 35 percent. Stricter environmental requirements and rising energy prices are expected to increase demand for low temperature asphalt.

The smoke disappears

A common method to keep the viscosity of the binder down is to add chemical or organic additive for instance wax. The function of the additive is to reduce the surface tension of the binder. In that way you get the same bonding effect as the high temperature delivers in a conventional asphalt with the result that the binder coats the stone material properly. Foam technology can also be used for this purpose. The foam makes the binder expand, become softer and provide a lubricating effect. But regardless of method, experience shows that it is not possible to use penetration bitumen below 120 degrees because it is too stiff. It is also difficult to guarantee proper drying of the aggregates at lower temperatures.

Investments in asphalt plants

Lorentz Lundqvist is product manager for NCC Green Asphalt. He says that asphalt plants are continuously rebuilt to produce low temperature asphalt.

“In the current situation about 20 percent of the plants are rebuilt, but figures are rising as the demand increases. The long-term objective is that all plants should be able to produce NCC Green Asphalt, as part of the effort to reduce the environmental impact of the industry”.

Better work environment

The asphalt workers are positive about the new low temperature asphalt. The mix behaves a little differently, but if the procedures applicable to hot asphalt are followed, the end result is the same. However, it can sometimes make hand-laying of the asphalt more difficult.

“With the new method the smoke disappears almost entirely; a drop of 10 degrees halves the amount of smoke. In summary, everything has gone very well, both in terms of the work at the plants and the quality of the finished product,” concludes Lorentz Lundqvist.

Dynapac paver and rollers on the job in Taipei city.

Magnificent road construction demonstration in Taipei Attended by some 300 officials and contractors, an impressive road construction demonstration was carried out on a stretch of 300 meters on a public street in Taipei city center.

Taiwan is a country small in size but with a growing economy and a big need for new and improved infrastructure.

Traditionally, Taiwan has been a market for old, secondhand equipment mainly imported from Japan. Old machinery in combination with little knowledge on how to operate the equipment correctly has resulted in poor road conditions and many motorcycle accidents. The lack of local service, training and application support has in the past been a major challenge for many road construction contractors in Taiwan.

The road construction demonstration in Taipei city is part of a larger stimulus plan initiated by the Taiwanese government.

The objective of the stimulus plan is to improve road safety, first in Taipei city and then followed by highway projects and continuing on to the rest of the country. The demonstration attracted a lot of attention. Close to 300 government officials and local contractors visited the site to learn more about high quality road construction and for the opportunity to see Dynapac equipment at work.

Uptime by design

on new North America Dynapac’s two new pavers have just made their official debut at World of Asphalt, where two tracked pavers were sold fresh off the production line. But long before the February WOA show, the pavers earned praise from operators who first used them during the test phase of manufacturing.

MYKE THURMAN, branch manager of Cate Rental & Sales, Salt Lake City, Utah, and his shop foreman and Product Support and Training Manager, Kevin Ford, were part of the team that helped review the pavers before they went into final production. They ran the pavers on four test sites in some extreme conditions to give product designers and engineers useful feedback. After the designs were finished and more testing completed, Ford said, “There was absolutely no problem with the mat. I have total confidence in it and I’d take it anywhere and do anything with this paver.”

“We worked with people who’ve been in paving their whole lives, and they say the new Dynapac paver is bulletproof,” Thurman said. “It’s important to us as a dealer to have a reliable product and to work with a company that can stand behind it.”

The F1000T tracked and F1000W wheeled 10-foot-wide asphalt pavers are truly new pavers – designed from the ground up with the contractor in mind. Along with the new paver design, Dynapac has committed to training operators and has a new parts and distribution system that promises to be more efficient than ever.

Reliability built-in The F1000 series pavers can handle extreme conditions in remote locations and are easy to operate and service. The proven components include Sauer Series 90 pumps, Sauer Series 51-1 motors, Sauer Plus 1 controllers, and a Sauer multi-function display. The reliable 24 VDC relay logic control system features relays and solenoid valves that can be operated manually. The availability of these

an pavers A Super Target parking lot was paved with 600 tons of asphalt in 90degree temperatures.

parts throughout the country means quick turn-around for maintenance and repair for maximum uptime on the site. Ford said, “The excellent serviceability comes from accessibility and using interchangeable and tried and true components.” Thurman added, “Our key customers were very impressed. Dynapac put computers only where they are needed.”

Easy does it Electronics in harsh environments can be an issue on some job sites, but not with the F1000 series pavers. The 24 VDC controls are located in a convenient, sealed electrical enclosure. The logic relays feature an LED power indicator, latching indicator and mechanical override for fast trouble shooting and quick replacement. The Sauer cartridge valves have a manual override, and the drive system is easily disengaged with an easy to use brake release system to move the paver in the event of a major failure.

No daily lubrication is required on the tractor, and two fuel tanks are at ground level for quick refueling. A single panel at the side gives full access to filters, and flip-open doors and a removable top cover give full access to the engine and hydraulic lines. There is a pressurized hydraulic filtration system with one-piece hydraulic valve manifolds offering simple maintenance. And for overall maintenance, the radiator and oil cooler have been designed to withstand pressure washing.

Bulletproof performance The three-quarter-inch formed hopper wings deliver asphalt to a high-capacity slat conveyor with a wide material tunnel and extra heavy chains and slats. A unique feature of the

Dynapac paver line is the high-performance outboard auger drive and the conveyor design, which eliminates the auger chain drive box.

Ford said, “There is no center line segregation with this outboard auger drive feature.”

Thurman said, “Our job is helping our customers make more money; the feature on this paver allows that to happen.”

The conveyor system can deliver up to 1,500 tons per hour of asphalt to either a Carlson EZ III or EZ IV screed to lay mats up to 12 inches deep on new placements, and thin overlays on rehabilitation projects. Ford said, “From the oversized hopper to the automatic feed system, this machine can really lay down the asphalt.”

The F1000 series is easy to operate with features and functions that have been designed with operator comfort and safety in mind. A 34 kW, 60 Hz generator provides full output at low idle for better fuel economy.

A paver to fall in love with The F1000 series features heavy welded frame construction, dual swing-out operator stations and the lowest deck height in the industry. The result is superior visibility for the operator, who has a clear view of the hopper and auger – and a full view of work area.

Ford said, “I never spent more than 30 minutes training an operator. Even the most skeptical operator fell in love with this paver.”

A return-to-center feature is an advantage on the F1000T, as well as a single lever for forward/reverse control. Fumes exhaust through the engine stack, reducing the crew’s exposure to asphalt fumes.

“Balance points won’t tear up the road base even when counter rotating; on a highway job with a 20-ton insert the paver remained well balanced with excellent speed,” Ford added.

“Thirty-five years of experience tells me this paver will pave anything − highway or parking lots with geotextile underlayment.”

Thurman added, “The paver allows the contractor to be diverse – paving highways or parking lots.”

The operator has a clear view of the work while sitting at the steering wheel.

The simple controls and multi-function display are operator friendly and grouped for convenience. The precision steering on the F1000T is tight, smooth and responsive, and the F1000T can be controlled by a travel speed set control for precise paving speed control.

Ask the Expert

Operating a roller involves much more than driving over newly laid asphalt.

It’s a skilled job that requires a keen eye for detail and an understanding of how asphalt behaves at different temperatures. Thankfully help is on hand with Dynapac’s real-time documentation system for roller operators.

Getting it right first time, every time OVER THE YEARS the day to day life of an asphalt operator has greatly improved. Innovations in cabin design such as air conditioning and vibration absorption make the ride conditions much more comfortable, while advances in technology have significantly speeded up the process. However, the job itself remains practically the same. With every new section to be rolled, operators need to ask themselves: what is the temperature of the asphalt; how many passes do I need to make; how many passes have I made so far; and when will the section be ready?

The extra pass

The operator’s aim, of course, is to make the optimal number of passes while the asphalt is within the correct temperature range. This is particularly important as final quality control is not carried out until the asphalt has cooled down and set. Unfortunately, this means that any mistakes are either permanent or extremely expensive to rectify – involving milling out the pavement and replacing it with new asphalt. And to avoid any uncertainty, operators therefore often make one or more extra passes over the hot mix, “just in case.”

In fact, research has shown that on a surface that requires six passes, the number of passes actually made varies from four to 14.

Under- or over-compacted asphalt obviously affects the quality of the pavement, but it also has direct financial implications for contractors. For example, by making extra passes, rolling capacity is being used that could be di-

rected to hotter more readily compatible mix.

Moreover, avoiding unnecessary passes also provides savings on fuel, resources and wear parts among other things.

Mapping certainty

With a documentation system such as Dynapac’s analyzer (DCA-A), these problems can be avoided, as operators can easily see how many passes they need to make on a hot mix before it cools down. Before this can be done, however, the operator needs to determine the number of passes necessary to achieve optimal compaction. The most common methods of doing this are running a test strip while checking the achieved density after each pass, or making a decision based on past experience.

Once the number of passes has been decided upon, this information, along with the ideal compaction temperature range, is entered into the documentation system, while the position of the roller is set according to a GNSS (Global Navigation Satellite System, ex.

NAVSTAR GPS or GLONASS) receiver with an accuracy of about 20 cm (8 in).

Once rolling begins, sensors continually measure and record the surface temperature of the mix and the system records the movements of the vehicle. This data is then relayed to the operator in the cabin via a color-coded touch screen otherwise known as a “compaction map” that changes color in a particular area when the correct number of passes has been made. As the map changes color the operator can move through the different sections.

Accurate compaction results

When the Quality Control Crew arrives to test the asphalt (usually with nuclear gauges and/ or core samples) they can check the results against the records from the documentation system. If the asphalt is poorly compacted it is easy to trace the process back and see where mistakes were made, i.e. asphalt temperature, asphalt specifications, number of passes, etc. However, if the compaction results are positive the information can be saved and used as a “best practice” case for future projects.

Benefits for all concerned

Using a documentation system to ensure pavement surfaces are optimally compacted provides a number of benefits for the different stakeholders.

Operators can focus on getting the job done as they do not have to second-guess where they have already made passes.

Contractors can optimize resources and use of their equipment, and reduce fuel consumption and wear and tear.

Road owners receive full documentation on the entire road surface rather than just a few tests made by quality control. Moreover they get assurances of high quality roads with a longer life.

Road users get to where they are going quicker as high quality roads mean less frequent repairs and therefore fewer traffic disruptions.

Dynapac welcomes the CC384HF roller to the CC family Dynapac is proud to offer a 9.5-ton roller in the 1730 mm (68 inch) drum width class.

Like all Dynapac rollers, the CC384HF is designed with efficiency in mind: application efficiency, operator efficiency, compaction control efficiency and service efficiency.

Performance, visibility, operator comfort, compaction control and serviceability for the CC line will appeal to owners, operators and service crews. The environmental benefits will appeal to everyone.

Highest availability

◄

There are a number of features to the new CC384HF to make servicing quick and easy, ensuring maximum uptime.

The use of a double pump vibration system eliminates the need for a vibration valve, making the system more efficient, aiding servicing and reducing fuel consumption. Both pumps – one for the front drum and one for the rear – can simply be shut off. A watertank with a volume of 900 liters provides ample water resources.

◄

Highest quality

◄

With the CC384HF roller you achieve high quality surface finishes through operational features such as soft starting and stopping to prevent unevenness or cracking in the asphalt layers. This allows even an unskilled operator to start and stop without leaving marks. As a safety feature, the machine will drop out of the soft mode and brake immediately if the lever is moved quickly, signalling the need for an emergency stop.

Highest visibility

One of the ways of achieving high quality compaction is to optimize the ergonomics, ensuring that operators have continuous visibility of the operation and comfortable access to the controls. The installation of the watertank in the front frame helps the CC384HF offer a 1 x 1 meter view and full visibility of all working functions.

You can tailor your roller to local conditions, including engine power, operator´s station and air conditioning.

True love is perfection A successful compaction job demands that the roller meet the compaction specifications required for the project. Improper operations such as bouncing can damage the roller, while excessive compaction costs time and wastes fuel without improving the quality of the mat.

Dynapac gets to the heart of the matter with its new generation Compaction Optimizer (DCO), an innovative system based on the well-proven compaction meter. Ground stiffness determines the input value for the amplitude setting of the vibratory drum. The operator is in full control, so compaction goes smoothly.

As an added benefit, the DCO system now includes the handheld wireless CompLogger. Quickly and easily installed, the CompLogger features cost-efficient CCC, extraordinary storage capacity and full analytical and printout functions for continuous compaction data during compacting.

The Dynapac Compaction Optimizer and CompLogger – a perfect match for people who love perfection.
