  5. NEED FOR HTPTF • To develop new specifications for P-401 (based on gyratory compactor) and other HMA related projects, R&D has relied mostly on laboratory testing. Full-scale tests are needed so that the performance prediction models for HMA from laboratory tests can be validated/calibrated to the in-situ pavements. • NAPTF – ideal for testing pavement structure as a whole, not for surface layers. HTPTF WILL PROVIDE THAT CAPABILITY.

  6. HVS-A Specifications • Wheel loads - 10,000-lbs (45 kN) to 100,000-lbs (445 kN) • Pavement temperatures up to 150 deg.F. • Test speeds - 0.17 mph (0.27 kmph) to 5 mph (8 kmph). • Single and Dual-Wheel configuration. • Wander Width – 6-feet

  7. HVS-A Specifications • Single wheel tire to be used will be radial aircraft tires size 52x21.0R22 mounted to steel rims built to government furnished drawings and specifications. • The dual wheel assembly - designed to accommodate tires of smaller sizes (such as Boeing 737-800) mounted to steel rims built to government furnished drawings and specifications.

  8. Proposed HMA Research at HTPTF • “Green” technologies such as Warm Mix Asphalt • Stone Matrix Asphalt • Asphalt overlays of PCC • Recycled Asphalt Pavement • Polymer Modified Binders
