n 26 February Infrastructure Australia released its priority list, a list that helps government and the private sector determine the country’s most important infrastructure projects. The latest edition presented 147 infrastructure proposals of national significance, the largest number since the list’s inception. This year, the list introduced five new high priority national initiatives, one of which was road maintenance. Infrastructure Australia recognised the cost to maintain roads in Australia is growing and the overall maintenance backlog is increasing. One of the major road construction activities that will be used in an effort to deplete the maintenance backlog is road profiling. Depending on the level of damage, profiling can be used to remove layers of the road and in preparation for new products to be laid. With road construction materials varying across Australia, every road profiling job is different. Wirhan Prationo, Bestech Marketing 40

Engineer, says project managers need to be informed with the correct data of the pavement’s condition before profiling begins, and this can be done using sensor technology. “Sensors provide measurements of the distance to the road which can be translated into roughness, depth and other datasets. This data can then be applied by engineers and operators to schedule proper maintenance when planning projects,” Mr. Prationo says. Bestech Australia is a an Australian-based sensor, instrumentation and technical
transport industry. Specific for road profiling applications, Bestech offers two different types of noncontact displacement sensors from MicroEpsilon, the laser triangulation sensors and laser profile scanners. Mr. Prationo says these sensors are the most popular technologies in this field as they are easy to apply to road profiling projects. “The single point laser or laser triangulation sensor, optoNCDT, is suitable for applications where the operators need to obtain only the rough profile of the road. Multiple single point laser triangulation sensors can be
