This paper presents results of triaxial compression tests on samples of medium uniform sand before and after stabilization with bituminous binders. The test procedure was designed to obtain basic shearing strength characteristics of sand and sand-bituminous mixtures at varying initial void ratios. Specimens were tested at two different strain rates. The equipment and methods used in preparing and testing specimens are discussed. A technique whereby the Mohr rupture envelope can be obtained using one test specimen is described. Test results are analyzed to show: The effect of initial density on the peak and ultimate strength of cohesionless soils. The merits of an open triaxial test procedure whereby the stress conditions are varied during testing in order to obtain the Mohr rupture envelope using one specimen. The effect of bituminous binder addition on the shearing strength characteristics of sand-bituminous mixtures.
