| 摘要： | As a result of the research conducted for the Strategic Highway Research Program (SHRP), a set of new testing methods to characterize the rheological, failure, and durability properties of asphalt binders has been developed. These methods use testing devices that either are completely new or that have been used before only for research purposes. The methods also call for measuring mechanical response parameters that are not very common for asphalt pavement engineers or for many asphalt producers. The purpose is to discuss the following points: (a) the viscoelastic nature of asphalts and its relation to pavement performance, (b) the concepts behind selecting the new test methods and the new characteristic properties, and (c) how the new measured properties compare with the conventional properties. These points are addressed by providing a theoretical-conceptual background about the conventional and new tests and by comparing new and conventional data measured for a large number of asphalts that vary in their sources and their grades. The comparison identifies the advantages of the new testing methods and the need to implement the proposed testing and specification system. |
