QUESTIONS AND ANSWERS FOR
Asphalt Mixture Performance Tester (AMPT)
Solicitation No. 69056719Q000026 Updated 6/20/2019 11:59 AM adding question 2
1. Can the two labs tell us who they use for calibration services?
No. This information is irrelevant to the solicitation but will be released to the vendor who receives the contract award.
2. The AASHTO T 378 standard for dynamic modulus testing requires attaining a cooling gain to 4 degrees C within 5 minutes after opening and closing the temperature chamber. Such requirement asks for superior temperature ramping of at least -0.8 degree C per minute between ambient and -5 C. I can't see this criteria…
Refer to paragraph B.3 which states “Fully compliant with NCHRP Report 629 and is capable of performing the three asphalt mixture tests noted in NCHRP Projects 9-19 and 9-
29. Dynamic Modulus, Flow Number and Flow Time, including AASHTO T 378 (formerly TP 79), AASHTO TP 107, and AASHTO TP 116.”
