| 摘要： | The primary objective of National Cooperative Highway Research Program (NCHRP) Project 9-29 was to stimulate the development of commercial testing equipment to perform the three simple performance tests recommended in National Cooperative Highway Research Program (NCHRP) Project 9-1 dynamic modulus, flow number, and flow time. The commercial Equipment developed in National Cooperative Highway Research Program (NCHRP) Project 9-29 was originally called the Simple Performance Test System. The name was changed to the Asphalt Mixture Performance Tester (AMPT) when the Federal Highway Administration (FHWA) assumed responsibility for its implementation. In Phases I and II of National Cooperative Highway Research Program (NCHRP) Project 9-29, a detailed purchase specification for the Asphalt Mixture Performance Tester (AMPT) was developed and two first-article devices were procured and evaluated. This evaluation concluded that the Asphalt Mixture Performance Tester (AMPT) is a reasonably priced, user-friendly device for testing stiffness and permanent deformation properties of asphalt concrete. |
