Uniaxial Tension Tests on Cement-Stabilized Granular Materials
This paper presents details of tests to evaluate the suitability of a double scissor friction grip system, initially developed for conventional concrete, for determining uniaxial tensile strength of cement-stabilized granular materials suitable for use in roadbase construction. The system is examined in terms of the variability of the results, the significance of fracture location, and the distribution of strain, and is judged to show promise. Test results on a cement-stabilized gravel, typical of roadbase materials used in the United Kingdom, are given, including the stress-strain characteristics in tension, the moduli of elasticity in tension and compression, and the strengths in tension, compression, and flexure.
