13. ABSTRACT (Maximum 200 words)
The U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) conducted various laboratory tests
on pavement materials from the Mn/ROAD facility. The tests helped to characterize the behavior of materials
under season frost conditions, and to provide input necessary for modeling the materials 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 moisture content of two subgrade samples and two base materials from Mn/ROAD.
