Abstract:

This project aimed to develop software to standardize and automate the calculation of stripping inflection point (SIP) from the Hamburg Wheel Tracking Test (HWTT) for evaluating the moisture susceptibility of asphalt mixtures. A survey of state highway agencies (SHAs) was conducted to collect information on their use of HWTT to evaluate asphalt mixtures. Based on the survey responses and consultations with HWTT equipment manufacturers, seven SIP calculation methods were identified, synthesized, and critically reviewed for comparison. These efforts resulted in selecting the most robust method for software development. Finally, a web-based program, named HWTTXpert, was developed through alpha testing at the National Center for Asphalt Technology (NCAT) at Auburn University and beta testing with 12 SHAs and three equipment manufacturers. The program is now accessible at http://HWTTXpert.eng.auburn.edu, with login credentials available upon request.
