The development and evaluation of protocols for the laboratory characterisation of cemented materials

The study involved a laboratory assessment of two cemented materials to assess their strength, modulus and fatigue properties. The cemented materials consisted of a hornfels crushed rock and a quartzite siltstone bound with general purpose cement at 3 per cent and 4 per cent addition rate by mass respectively. The laboratory testing involved unconfined compressive strength, indirect tensile testing and flexural beam testing. Samples were prepared in the laboratory and from field placed cemented material and cured for a variety of periods from 7 days to over 500 days prior to testing. The study showed that the flexural beam test was a suitable means for assessment of the modulus and fatigue of cemented materials and that load damage exponents for the cemented materials varied between about 6 and 8. The laboratory results are to be compared with full scale accelerated pavement test results as the next stage in the overall research project. (a)
