The Hamburg wheel-tracking device (HWTD) test has been gaining acceptance by some state highway agencies. Although a few studies showed that test results from this device have the potential to evaluate the moisture sensitivity of asphalt mixes, the correlation between the test results and field performance has not been widely studied and well established. The capability of the device to predict field performance therefore has not been sufficiently validated. The study presented evaluates the effectiveness of the HWTD test in determining the moisture sensitivity of asphalt mixes and in predicting field performance by using both laboratory test data and field performance data. It was found that the current test procedure may give false positive and false negative results. Binder properties have a significant effect on the test results. The correlation between the test results and field performance was unsatisfactory. Recommendations for potential improvement of the test are provided.
