5. 5 Federal Aviation Administration High Temperature Pavement Test Facility (HTPTF) April 24, 2012 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.
