title AutoPave: towards an automated paving system for asphalt pavement compaction operations
source Automation in Construction 8 (2) (1998) pp. 165-180
summary Asphalt pavement density from roller compaction is a crucial factor in ensuring satisfactory pavement performance. Proper and uniform compaction of the pavement mat is essential in achieving the desired final compacted density. There is a necessity to investigate existing pavement construction practices, and provide more cost-effective modifications to the current scenario. Automation of the paving operation can increase the efficiency and quality of the operation, lead to reductions in overall project costs and time, and enhance pavement life. A system can be developed through algorithmic planning and real-time guidance strategies, and the development of a semi-automated path-planning and real-time guidance system that aims towards automating the paving operation. This system accepts relevant paving project inputs, generates appropriate path plans for the compactor, performs a graphical visualization of the generated path plan, and offers real-time guidance capabilities using Global Positioning Systems (GPS) technology. This system, named AUTOPAVE (v1.0), was developed in Microsoft Visual Basic™ programming language and offers a user-friendly and interactive graphical interface. The proposed new system will incorporate state-of-the-art GPS technology to standardize paving operations that are more amenable to rigorous quality control, and can result in considerable reductions in cost and time involved in asphalt pavement construction projects. This system was tested on several actual paving projects, and many operational issues related to the functioning of the system were successfully overcome.
