| 摘要： | A primary objective for the Strategic Highway Research Program (SHRP) A-003A contract was to extend and verify the results obtained by other SHRP contractors on the performance-related characteristics of asphalt binders in paving mixes. This report specifically addresses validation of the following: 1) binder properties proposed by the A-002A contractor to predict asphalt-aggregate mix performance in terms of fatigue, permanent deformation, and thermal cracking; and 2) conditioning procedures that produce binder properties representative of those in a pavement immediately after construction and after several years of service. While water sensitivity requirements are not included in the binder specification, validation efforts in the water-sensitivity area are also described. Materials used in the investigation included 8 to 16 asphalt binders and 2 to 4 aggregates obtained from the SHRP Materials Reference Library. Overall, the findings are encouraging for the SHRP binder properties for thermal cracking and fatigue but are not very definitive for permanent deformation. Moreover, for aging and water sensitivity, the interaction between the asphalt and aggregate affects performance and underscores that these variables must be considered in the mix evaluation. |
