Results from this study show that the Georgia Loaded-Wheel Tester (GLWT) is capable of rutting in asphalt pavements prior to construction. In addition, results from the GLWT correlate well with results from more expensive European testers.

 

This report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to better understand how selecting an Mr value influences the thickness of an asphalt overlay pavement. The objectives of this study were to: 1) investigate the importance of several...

 

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...

 

The report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to examine the factors influencing the determination of a subgrade resilient modulus (Mr) value. The objectives of this study were to: (1) investigate the importance of several fundamental...

 

The objectives of this initial study were 1) investigate the relationship between resilient modulus and R-value; and 2) develop a predictive equation for resilient modulus based on easily measured soil properties. Thirteen different fine-graded soils were investigated. Based on the test results, two...
