Development and Verification of the Overlay Tester Based Fatigue Cracking Prediction Approach (With Discussion)

The purpose of this paper is to present the overlay tester (OT) based fatigue cracking prediction approach in which the OT is used to determine fracture properties (A and n) of Hot-Mix Asphalt (HMA) mixtures. This approach was developed based on fracture mechanics. However, not only was the fatigue crack propagation characterized by Paris’ law fracture concepts, but the crack initiation was described by traditional fatigue model (Ni=k1(1/ε)k2) was also included in this approach. For this approach, the fundamental HMA fracture properties (A and n) were used to estimate fatigue life of asphalt pavements including crack initiation and crack propagation. Note that the traditional fatigue (crack initiation) model parameters: k1 and k2 were also estimated from the fracture properties (A and n) through a quantitative relationship which was established based on theoretical investigation and historical bending beam fatigue test data (1348 data sets). Field verification of this OT based fatigue crack prediction approach was demonstrated with performance data collected from the Federal Highway Administration’s Accelerated Loading Facility (FHWA-ALF) test program. The proposed approach has been successfully verified by analyzing five FHWA-ALF fatigue test lanes. The ranking of the predicted fatigue life for the ALF test lanes had a very good agreement with the measured fatigue performance data under the ALF loading. However, further field validation using other data sets is still needed.
