摘要: The project evaluated previously recommended aggregate tests related to hot-mix asphalt (HMA) performance and, based on the results of laboratory tests and accelerated tests of full-scale pavement sections, developed recommendations for a set of eight performance-based aggregate tests and provided guidance on using these tests for evaluating and selecting aggregates for use in specific mixture applications. The properties of coarse and fine aggregates used in HMA mixtures significantly affect the performance of the highway pavements in which they are used. Despite their obvious importance, little consideration is usually given to the testing of aggregates. Many currently used aggregate tests are empirical--they were developed without establishing a direct relation to pavement performance. Furthermore, some of the most commonly used test methods are not easy to perform and do not yield reproducible results; compliance with these tests does not consistently result in acceptable performance. Thus research was needed to recommend precise tests that measure key aggregate properties related to pavement performance. / Supplementary Notes: uee also Main Report, PB2007-101237.
