FATIGUE OF ASPHALT CONCRETE MIXTURES-SUMMARY OF EXISTING INFORMATION

DATA ARE PRESENTED ON THE FATIGUE BEHAVIOR OF ASPHALT CONCRETE MIXTURES BASED ON A REVIEW OF THE LITERATURE, AS WELL AS RESEARCH, WHICH ILLUSTRATE THE EFFECTS OF A NUMBER OF MIXTURE VARIABLES ON FATIGUE RESPONSE AND INCLUDE AN INDICATION OF THE INFLUENCE OF: MIXTURE STIFFNESS, AIR VOID CONTENT, AGGREGATE GRADATION, AGGREGATE TYPE, ASPHALT CONTENT, AND ASPHALT TYPE. A LITERATURE REVIEW INDICATES THE VARIATION TO BE EXPECTED ON TYPICAL CONSTRUCTION PROJECTS. THIS INFORMATION TOGETHER WITH THE FATIGUE DATA PRESENTED PREVIOUSLY ALLOWS THE ENGINEER TO ASSESS THE RELATIVE IMPORTANCE OF THESE MIXTURE VARIABLES ON PREDICTING THE PERFORMANCE OF PAVEMENTS. ASPHALT CONTENT AND TEST TEMPERATURE APPEAR TO BE MORE CRITICAL THAN THE VARIATION ASSOCIATED WITH AGGREGATE GRADATION, ASPHALT HARDNESS, AND AIR VOID CONTENT. /DOT/
