Quality control of asphalt compaction using GPS-based system architecture

This paper describes research to develop a GPS-based automated quality control system for tracking pavement compaction. The research team has experimented with both vector and raster based algorithms and believe that the raster-based algorithm may be more efficient in this application. Simulated tests on CTS-111 have been extremely encouraging, and the team continues to improve the system for testing. After the tests are completed, the researchers are confident that this technology can be fitted in existing compactors at a cost of about $10,000 per compactor, including GPS devices, radios, hardware, and software.
