  • Abstract:
    The objectives of this study are to evaluate the performance of a local aggregate in HFST and to evaluate ; the 3-dimensional laser profiler for measuring pavement texture. Slab specimens of hot-mix asphalt ; (HMA) were compacted in the laboratory and treated with HFST systems incorporating both calcined ; bauxite and a local, hard flint aggregate from Picher, Oklahoma. The treated HMA specimens were ; then tested with a Dynamic Friction Tester (DFT) and a Circular Track Meter (CTM) to determine the ; frictional coefficient and texture depth, respectively. Also, Hamburg Wheel Tracking Device tests were ; conducted on these HFST systems to evaluate wearing resistance under repetitive wheel load. Field ; measurements of texture depths on HFST were also done. Statistical analysis was performed to compare ; the performance of high friction surfaces prepared with different aggregate epoxy combinations. ; The results show that flint aggregate can be a suitable substitute for the calcined bauxite in HFST. ; Field measurements also showed marked improvements in texture depth with HFST. Texture depth and ; skid number determined by the ASTM skid trailer vary with pavement surface types and treatments. ; Mean Texture Depth (MTD) of high friction surface treatment is generally greater than 1 mm. A good ; correlation between skid number and MTD was found for the MTD range of 0.5 to 1.5 mm.
