Issue A number of states will (or have) purchased an AMPT – Most recently in the FHWA Pooled Fund study Limited training accompanied the purchase Important for states to have proper knowledge of equipment, test procedures, and data reduction as AMPT moves towards implementation – MEPDG – WMA and RAP mix evaluations – HMA Performance specifications and general research

Main Purpose To provide a forum to educate current and future AMPT users on the proper use and implementation of the AMPT – Similar to what was previously done with the MSCR test by NEAUPG Members would consist of representatives from: – Highway agencies – Industry – Academia

Members Lead Members – 1 each from industry, state agency, and academia Tom Bennert from Rutgers to lead – Help to organize round robin testing and training Members – Any member of NEAUPG using and/or procuring an AMPT for HMA mixture evaluation

Immediate Activities Required Volunteers for Lead Member representation – 1 each from industry, state agency, and academia in the northeast Survey of AMPT Users in the northeast – Some now on order through Pooled Fund; when will they be arriving Volunteers for initial round robin study on dynamic modulus and flow number

Proposed/Future Activities Develop website – AMPT information hub for the NEAUPG – Home to specs, best practices, research, current activities Precision and Bias for current AASHTO TP79 based on Round Robin work – Dynamic modulus – Flow Number Workshops on data reduction and analysis Updates/Workshops on additional tests for AMPT – Continuum Damage Fatigue (Push-Pull) – Dynamic Modulus in IDT Mode
