DESIGN OF REAL-TIME SITE OPERATIONS CONTROL FOR IN-PLACE ASPHALT PAVEMENT RECYCLING

Recent improvements in computer technology have advanced industrial processes toward more autonomous control, with opportunities that offer superior handling, reliability, and enhanced overall quality. Although the highway construction process has advanced over the years as a result of rapid improvements in material technology, the on-site construction process still remains, for the most part manual. This is attributed primarily to the variability that exists on the road sites, creating situations that, under normal circumstances, are difficult to project and replicate from site to site. The use of automated equipment for hot in-place asphalt resurfacing is discussed as a modern technique that has advanced and provides the potential for further automation and improvements to current in-place technology. Breakthroughs that have been achieved by the authors toward improving this particular site process through real-time data handling are also discussed. The specific approaches are addressed that have been taken to automate and improve the process by incorporating the development of a nondestructive field-sensing process for identifying pavement and material characteristics, a blackboard procedure for field decision making based on real-time decision response to field conditions and information, and computerized process control that allows the integration of these new technologies with present equipment technology.
