Data and conclusions from a 6 yr field study of subgrade moisture under highways are presented to show the effects of soil, climate, and highway design on moisture. Effects of subgrade moisture conditions on expansive subgrade volume change and overall highway performance are described. Moisture contents were found to increase, over a 2 yr interval, from original conditions to an equilibrium value of 1.1 times to 1.3 times the subgrade plastic limit.
