    Abstract

    This paper presents the results from an experimental study on the characterisation of lightly stabilised granular base materials by monotonic load/displacement flexural beam testing which was carried out on two granular base materials lightly stabilised with 1 % to 3 % cement—fly ash. Effects of the loading/displacement rate on the flexural properties (i.e., flexural strength and stiffness modulus) of the lightly stabilised granular base materials were investigated and they were found to be loading/displacement rate-dependent. The suitability of an improved (newly developed) flexural beam testing setup with internal deflection measurements, which was employed to determine these flexural properties, was also examined. Test results indicate that this improved flexural beam testing setup can be used reliably for characterising lightly stabilised granular base materials.
