Abstract : Four highway pavement test sections were built at CRREL in July 1971. Two sections were designed using the Asphalt Institute full-depth criteria in which the pavement is placed directly upon the subgrade with no granular base course, and the other two were based on similar traffic volumes using the Corps of Engineers reduced subgrade strength criteria which incorporate a granular base course. The sections were constructed to compare and evaluate the performance of the two different concepts under freeze-thaw conditions. The first three years' observations are reported.
