Final Report Abstract
In this research the feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated. The study consisted of modifying the GLWT to handle 15.2 cm (6-in.) cores, obtaining asphalt pavement cores from several test sites throughout Wyoming, collecting rut depth data, compiling the data in a computerized database, and conducting statistical analyses. The analyses resulted in preliminary regression models that can be used to predict field rutting based on rut-depth measurements from the GLWT. More data will be obtained to verify the regression models.
