Abstract:

A SYSTEM FOR PREDICTING THE STIFFNESS HISTORY OF AN ASPHALT CONCRETE PAVEMENT LAYER THROUGHOUT ITS DESIGN ANALYSIS PERIOD HAS BEEN DEVELOPED. THE SYSTEM USES STANDARD MATERIAL PROPERTIES AND ENVIRONMENTAL INPUTS TO PREDICT THE DAILY CHANGES IN STIFFNESS DUE TO TEMPERATURE VARIATIONS AND ALSO THE LONG-TERM CHANGES IN STIFFNESS DUE TO HARDENING OF THE ASPHALT CEMENT GINDER. THIS SYSTEM WAS DEVELOPED AS PART OF AN OVERALL SYSTEM FOR THE PREDICTION OF LOW-TEMPERATURE AND THERMAL-FATIGUE CRACKING IN FLEXIBLE PAVEMENTS. THE FOLLOWING PROCEDURES AND MODELS WERE DEVELOPED FROM ACTUAL PROJECTS AND OTHER RESEARCH RESULTS: MODELS TO ESTIMATE THE ASPHALT CONCRETE STIFFNESS FROM THE ORDINARY LABORATORY MEASUREMENTS, PROCEDURE TO ESTIMATE THE LOADING TIME FOR TEMPERATURE, AND MODELS TO PREDICT THE INSERVICE AGING OF ASPHALTS. THE SYSTEM HAS BEEN USED IN PREDICTING LOW-TEMPERATURE AND THERMAL-FATIGUE CRACKING AND HAS SHOWN A GOOD DEGREE OF RELIABILITY.
