MULTIAXIAL TESTING OF SUBGRADE

A unique testing apparatus consisting of a low-pressure multiaxial device has been applied to resilient testing of subgrade soil. Tests were conducted by applying dynamic loading under constant confining pressure. Soils from seven Ohio sites were evaluated. Laboratory results indicate that resilient behavior of the subgrade was dependent on moisture content, stress level, soil type, and density. Critical sensitivity of the resilient modulus to the moisture content was demonstrated by experiments. The testing procedure and results are discussed.
