| 摘要： | WesTrack was the Federal Highway Administration's (FHWA) test facility in Nevada for developing performance-related specifications for hot-mix asphalt pavement construction. It also provided some of the earliest data on the performance of Superpave asphalt mixture designs under high rates of heavy truck loading. When Superpave-designed test sections placed at the track in June 1997 had very rapid rutting failures, the highway community was concerned that the mixture design and construction procedures might be missing important, but unknown, constraints. A forensic team composed of academicians, asphalt industry representatives, and State highway agency engineers was assembled to study the early failures and, if appropriate, to make recommendations for revising the Superpave procedures. Their examination of the failures resulted in Report No. FHWA-RD-99- 134, Performance of Coarse-Graded Mixes at WesTrackPremature Rutting, which is available from FHWA. |
