MIX AND MODE-OF-LOADING EFFECTS ON FATIGUE RESPONSE OF ASPHALT-AGGREGATE MIXES (WITH DISCUSSION)

A series of accelerated performance-related tests for asphalt-aggregate mixes was performed under Project A-003A of the Strategic Highway Research Program's (SHRP) asphalt research activity, and methods were developed for anlyzing asphalt-aggregate interactions which significantly affect pavement performance. The fatigue investigation evaluated a number of promising testing systems both under controlled-stress and controlled-strain modes-of-loading. The specific objectives of this paper are to explore mix and test variable effects including those of mode-of-loading, on the fatigue response of asphalt aggregate mixes. Following a brief description of the laboratory test program on which the analyses reported are based, the paper examines the effects of various mix properties on fatigue life. Attention is then turned to exploring the effects of mode-of-loading on in-situ mix performance.
