UTILIZING THE GEORGIA LOADED-WHEEL TESTER TO PREDICT RUTTING
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.
