Abstract : The U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) conducted various laboratory tests on pavement materials fromthe Mn/ROAD facility. The tests helped to characterize the behavior of materials under season frost conditions, and to provide input necessary for modeling the mateirals with the Mechanistic Pavement Design and Evaluation Procedure under development at CRREL. This report describes test results that define the physical characteristics, such as grain size, specific gravity, Atterberg limits, organic content, and compaction, as well as hydraulic properties, such as moisture retention and hydraulic conductivity, frost susceptibility, and unfrozen mositure content of two subgrade samples and two base materials from Mn/ROAD.
