Conference Paper

The Stellenbosch University in South Africa has recently undertaken a research project on selected cold mixes. The focus of this paper is on the behaviour of these mixes in the monotonic and repeated loading tri-axial test. The test matrix included both bitumen emulsions and foamed bitumen mixes. The results of the monotonic tri-axial tests were explored for useful information other than the standard shear parameters. This includes tangent and secant moduli and strain-at-failure from the engineering stress-strain diagram. For the repeated load tri-axial tests the initial strain, strain rate and combinations of strain and strain rate that lead to failure were investigated. A strain rate threshold as function of the strain is provided. © 2007 Taylor & Francis Group, London.
