National Pooled-Fund Workshop on Asphalt Mixture Performance Tester (AMPT).

摘要

Pooled?fund study TPF?5(178) was initiated in 2008 to support the implementation of the Asphalt Mixture Performance Tester (AMPT) for Superpave mix design and for asphalt pavement design and analysis. The study has procured the AMPT and provided technician training for participating highway agencies to perform the standard tests for measuring dynamic modulus (E) and flow number (Fn) of asphalt mixtures. Based on the inputs from the pooled?fund participant agencies collected by FHWA, a national workshop for AMPT users was one of the implementation support activities identified as important tasks within the pooled?fund study. Thus, a national pooled?fund workshop on AMPT was organized in Atlanta, GA, on September 11 and 12, 2012, to support the AMPT implementation effort. The workshop gathered together pooled?fund study participants as well as users and experts in AMPT testing. The workshop provided a forum to discuss the development and implementation of AMPT and relevant test procedures for evaluating the performance of asphalt mixtures and providing inputs for the DARWin?ME pavement design.
