AASHO Road Test Effect on Pavement Design and Evaluation After 50 Years

The AASHO Road Test construction and testing occurred from 1956 to 1961. Significant results from the Road Test still influence pavement design worldwide, including: Equivalent Single-Axle Loads (ESALs); the serviceability–performance concept; effects of layer thickness and strength; and effectiveness of dowels and joint spacing. The AASHO Road Test results are the basis for pavement design still widely applicable and currently used. It also changed the way that people conduct pavement research by illustrating the power of factorial experiments, high-quality data, and statistical analyses.
