COMPARISON OF RESULTS OBTAINED FROM THE FRENCH TESTER WITH PAVEMENTS OF KNOWN PERFORMANCE. FINAL REPORT

The French rutting tester has been used successfully in France to eliminate the occurrence of rutting. The Colorado Department of Transportation (CDOT) and the Turner-Fairbank Highway Research Center (TFHRC) were selected to demonstrate this equipment. Thirty-three sites across Colorado with good and poor performance and a variety of temperature and traffic conditions were selected. Test results indicated that the French rutting tester, using the French specifications, was overly severe for many of the temperature and environmental conditions encountered in Colorado. However, by adjusting the testing temperature to match the highest temperature at a site location, the French rutting tester did an excellent job of predicting pavement performance. The results from the French rutting tester also had good correlation with actual rutting depths when temperature and traffic levels were considered.
