Behavioral Characteristics of Gravelly Sand and Crushed Limestone for Pavement Design
Repeated load triaxial compression tests were conducted to develop and establish laboratory equipment and procedures for determining the resilient properties and rutting potential of cohesionless soils. Materials tested were a crushed limestone and gravelly sand, which were used as base and subbase course layers, respectively, in prototype pavement test sections at the U. S. Army Engineer Waterways Experiment Station. The resilient properties were determined by subjecting single specimens to 100 load repetitions at various stress states (i.e., multistage tests), whereas the rutting potential was determined by subjecting comparison specimens to up to 100,000 load repetitions of a single stress state. The rutting potential of the two materials was about the same at lower stress ratios; however, at higher stress ratios, the rutting potential of the gravelly sand exceeded that of the crushed limestone. The rutting potential of both materials was found to be very small.
