A complex of high-performance mechanisms and machines, both large and small in capacity and productivity, make up the current system of road and building machinery. The development of road construction equipment is significantly impacted by the expansion of the network of paved roads, the employment of resource-saving technologies, an increase in the pace and quality of work, and the assurance of the dependability and longevity of highways. Asphalt is laid on highways, bridges, parking lots, and other such locations using modern paver equipment. Before a roller compacts the asphalt, it flattens the surface and offers some little compaction. The hydraulic loading legs that extend on today's paver machines make it simple to load and move them, and they also allow for quick width changes. Making the highest-quality pavement installation quicker and easier is at the heart of current trends in asphalt paving. In our most recent in-depth research, our panel of experts from five manufacturers look at innovations and technologies that are available in asphalt pavers, their level of use at the moment, the benefits they provide, as well as factors to take into account when looking to buy a new machine. A mechanical paver is essentially a machine that must be operated manually, whereas a sensor paver is an advanced version that functions automatically depending on the grade and slope of the material and the road, respectively. Sensor pavers come in a variety of variants depending on the technologies and capacities they can accommodate. Asphalt is laid on highways,

bridges, parking lots, and other such locations using modern paver equipment. Before a roller compacts the asphalt, it flattens the surface and offers some little compaction. The hydraulic loading legs that extend on today's paver machines make it simple to load and move them, and they also allow for quick width changes. The various types of paver machines used in road construction are covered below. Working of the Paver Machine When in use, an asphalt-filled dump truck approaches the paver's front and carefully empties its cargo into the paver's hopper. The feeder conveyors bring the asphalt to the paver's back as it advances, and the distribution augers spread it out to the proper width. The asphalt layer is subsequently levelled by the screed, which also partially compacts it into the required shape. The asphalt is then further compacted to the required thickness by a large, steel-wheeled roller that follows the paver. Rubber-tired pavers have four or more smaller solid rubber steering tyres and two big inflatable rear drive tyres. Pavers with rubber tracks have moulded synthetic rubber tracks that are reinforced internally with multiple layers of flexible steel cable. The load is divided among many intermediate rubber-coated steel bogie wheels, and the track is propelled by a friction drive wheel at the back. The forward wheel is pressed against by a hydraulic cylinder to keep the track taut. The paver's hopper receives asphalt from a dump truck or a material transfer unit. The asphalt is subsequently transported from the hopper to the auger by the conveyor. A pile of material is piled up in front of the screed by the auger. The screed spreads the material stockpile throughout the road's width and provides initial compaction. Behind the screed, the paver should give a uniformly smooth surface. Using a free floating screed, a smooth surface is provided. The base topological influence on the finished surface is lessened because it is being towed at the end of a long arm. The attack angle, weight, vibration, material head, and towing force of the screed are some of the variables that affect the height of the screed.

Modern pavers employ automatic screed controls, which typically adjust the screed's angle of attack from data obtained from a grade sensor, to adhere to the elevation changes for the final grade of the road. To rectify the final pavement's slope, crown, or superelevation, additional controls are applied. The paver should move forward at a constant speed and have a steady stockpile of material in front of the screed in order to generate a flat surface. The screed will rise as a result of an increase in material stockpile or paver speed, which will result in more asphalt being laid down, a thicker asphalt mat, and an uneven

final surface. Alternately, less material or slower speed will result in a fall in the screed and a thinner mat.

One of the reasons for employing a material transfer machine in conjunction with a paver is the requirement for continuous speed and material delivery. A material transfer unit enables continuous, contact-free material feeding to the paver, improving the final surface. When a dump truck is used to fill the paver's hopper, it can come into contact with the paver or vary its pace, which would lower the screed. On a paver, the engine, radiator, hydraulic parts, batteries, electrical wiring, instruments, steering wheel, and operator's seat must all be purchased. Hydraulic fluid, diesel fuel, engine oil, and antifreeze are examples of purchased fluids. There are two common ways used to pave pavement quality concrete (PQC), namely the slip-form approach and the fixed-form method. There are instances where PQC paving is done by hand. The manner in which the form work is fitted is the primary distinction between slip-form and fixed-form approaches. The formwork that is attached to the paver and moved throughout the paving process in the slip-form method. New Technologies in Industry The asphalt industry has moved away from traditional mix designs in favour of more robust, performance-based Superpave binder mix designs, which can withstand the traffic loading and weathering challenges of contemporary road use. A new generation of lab and field mix-testing tools as well as new full-scale accelerated pavement testing facilities have been made possible by modifications in asphalt mixes. Every day, decisions about pavement mix design

ine H ac m Paving

are made using the collected data to enhance long-term asphalt performance. The asphalt paving business has adopted cutting-edge new technology and research, recycled old asphalt pavement, and other industrial or waste materials into pavements, improving the environment and cutting costs. Asphalt mix quality and placement have improved thanks to infrared and electronic paving. Using an infrared camera and a global positioning system, thermal mapping measures the surface temperatures of asphalt. Contractors can fine-tune their operations for more uniform lay-down temperatures by viewing real-time temperatures, identifying discrepancies, and taking action to manage the plant to paver delivery process. Thermal imaging measures pavement temperature using an infrared bar mounted directly to the back of the paving machine. The system saves the data for further analysis while the sensors offer real-time temperature information. Contractors can handle thermal segregation issues by altering their paving procedures or making the appropriate modifications to the equipment when lay-down temperatures are monitored in real-time. Inset slipform pavers construct large-scale concrete pavements, such as extremely durable highways or aeroplane runways, cost-effectively. On request from the customer, modern inset concrete pavers can accurately pave concrete in widths ranging from 6 feet, 6 inches to 40 feet, and in thicknesses as high as 18 inches. These pavers enable for simple operation and precise paving. The first paver with a maximum operating width of 40 feet was developed by Wirtgen, allowing the operator to easily adjust to shifting job site conditions. It is a small vehicle with a trackline that enables paving next to obstructions.

Technical Details of a Paver Machine for the Road

Numerous elements of the paver equipment can be employed to construct a high-quality road. In order to process the material, the asphalt material must first be placed into the hopper of the paver machine. After the material has been transferred, the paver machine transports it to the auger apparatus. The auger equipment's function is to transfer concrete from the stockpile to the screed. The material is spread in the designated area of the road construction after being transferred to the screed unit. The road paving equipment also includes an automatic screening system and a screed regulating device in order to spread asphalt smoothly. The parts' job is to automatically operate the asphalt laying and processing system, and the screed controlling unit enables the machine to lay the stockpile of material without the need for any personal assistance. Additionally, the paver machine has controls for speed and height adjustment. It enables the equipment to change its speed and height in accordance with the demands and designed layout of the route. Importance of Paver Machine The need and demand for paver machines may rise for a variety of causes, some of which may be significant. One of the main issues that a road paver machine can help with is fixing potholes. Heavy rain or the possibility of

additional accidents on the roads might cause potholes, which are a major problem on the highways. By applying a thick layer of asphalt, the paver machinery has the ability to cover up the potholes. Once the equipment has been filled with concrete, cement, clay, or any other material, it can spread an even coating of asphalt. Road paver machines can be useful to the sectors that build roads in a number of ways. This road equipment could be a labor- and money-saving provider of equipment. Road cracks are a significant issue that can also be resolved with paver equipment. The equipment used for paving roads might be useful for filling in road cracks. This equipment is especially crucial since in addition to offering an asphalt laying method, it also has the ability to deliver a long-lasting stockpile of asphalt for minimising road damages on one or more roads.

Today's road construction companies needs a piece of equipment that can produce high-quality systems for processing and laying asphalt. The paver equipment is a type of road tool that may be used to meet various technical and non-technical requirements in the field of road building. The paver machine, on the other hand, offers additional advantages such an automatic shutdown system, a screen controlling system, etc. that may be utilised to build the infrastructure for roads, footpaths, and other pathways. Paving techniques have already developed to support more environmentally friendly practises. To rehabilitate roads, micro-surfacing currently entails spreading high-quality aggregates and bitumen emulsion mixed with polymers. This revised recipe lessens the quantity of dangerous gases released into the air, but it does not completely remove them. However, technology is available to further minimise environmental impact. It is overly optimistic to claim that promoting biking and walking in urban areas will mitigate the environmental harm caused by the paving industry. To conduct clean operations, businesses must outfit themselves with environmentally friendly equipment. Modern asphalt pavers include a sophisticated eco-mode function that alters engine speed depending on load circumstances. This increases the machine's performance and reduces fuel consumption by 5%.

Finding flexible, low-intervention solutions that can be finished quickly to minimise unwanted inconvenience to the public is a major concern for the paving industry. In the end, this is accomplished by having a strong infrastructure for product support from suppliers, one that will increase the lifespan of their equipment and decrease resource input. Another choice is to purchase old equipment. Used pavers, planers, and compactors are repaired and maintained so that the next user can enjoy the advantages of the environmentally friendly technology. Therefore, the paving industry shouldn't be concerned about buying used equipment. Machines that have been certified and warrantied enable repairs to be completed quickly, saving the construction workers' time and allowing paving to continue. CM

The Indian real estate industry went through a rough patch during the first and the second wave of COVID-19, but now the sector is showing signs of steady recovery. Changing consumer behavior, resurgence of demand, reopening of the economy, government initiatives and the adoption of real estate software are set to boost India’s industry with a big push. The sector constitutes 8% of the GDP, and close to 250 allied industries are deeply linked with the sector. After agriculture, real estate is one of the largest employment creators in India. All stakeholders, including developers, property owners, tenants, and other sub-sectors such as hospitality and retail have started to experience growth. At the same time, office spaces and industrial chains expect better performance with the reopening of offices and the rise of coworking culture. Impact on Real Estate

India is the 5th largest economy globally and a significant contributor to global economic growth. Hence, the backlash faced by the Indian real estate sector impacted not only India but also the entire world. India’s position as a lucrative investment market for real estate also faced bottlenecks amidst the global crisis. As the sector recovers, the market will continue to move in a fast direction amid pent-up demand. On the residential side, homebuyers are now scouting for projects that are spacious, deploy sustainable materials and are giving preference to self-sustaining societies. Since people were left stranded at their homes for a while, buyers now expect houses that promote decent living standards while being affordable at the same time. On the commercial side, successful vaccination drives, precautions and dipping cases have encouraged a hybrid culture that might pave the way for work from the office again. Still, developers must face many challenges such as a prolonged state of weak liquidity, cash flow issues, low labor availability and lack of long-term leasing opportunities before expecting a full-fledged recovery. Change in buying patterns

encounter long-term effects induced by the pandemic, including industry-wide real estate software adoption, changing buyer patterns and more. The demand for real estate properties for the short and long term might face a permanent shortage amid pent-up inventory. Furthermore, the increasing preference for eCommerce and online shopping is decreasing the revenues for physical stores and malls, which is a significant component of the real estate sector. Pace Up Recovery with Technology

The pandemic made the world comprehend the unique importance of technology and how it can be a life saver for businesses, especially for real estate and infrastructure sectors. Hence, developers were compelled to rethink their business operations and make digitization and deep analytics capabilities, their absolute priority. New-age real estate digital transformation solutions and advanced enterprise technologies such as AI, IoT, ERP, RPA, robotics and data technologies can proactively facilitate commercial lease negotiations, enable tenant churn, prompt asset valuation and increase visibility and productivity. These technologies aim to reduce the recovery time while boosting business outcomes at speed. Pacing up the construction sites with advanced technology helps to monitor more effectively with real-time analytical data and predict with high accuracy for uncertainties like glitches, snags, operational issues, working complications, delays, or malfunctions. This predictive capability prevents delays, operations stoppage, over-costing and process downtime. With this widespread adoption, we are entering an era of digital irreversibility where new-age technologies such as real estate ERP will ensure smooth functioning and improve growth prospects for the industry with sound capital deployment, effective property management, and virtual tours.
