Behavior of asphalt concrete mixtures in triaxial compression

Abstract

The triaxial compression test is one of the most common standard tests for determining the stress-strain behavior and strength parameters of soils under drained and undrained conditions. This paper describes the use of the triaxial compression tests for asphaltic mixtures for determining their engineering properties such as the friction angle Φ, the cohesion, c, and the elastic compression modulus, E. Effects of test temperatures, strain rate, and confining pressures on the compressive behavior of asphalt concrete were studied.
