This paper presents a discussion of the use of Mechanistic-Empirical (ME) analysis to simulate Accelerated Pavement Testing (APT) results in order to overcome problems with using APT data, such as differences in underlying conditions, construction quality, loading, and environmental control. This is particularly important when APT results are used for comparison studies between different pavement alternatives. In the process presented, APT results are first used to calibrate ME models so that

The APT results are then simulated with ME, this time assuming uniform conditions in the APT, to produce a ranking of the alternatives tested without the bias of differences between APT sections. Extrapolation of APT results to field conditions using ME analysis is also discussed. The paper presents a demonstration of this process from an experiment to compare different asphalt overlay treatments for reflective cracking and rutting performance.
