    Abstract

    Fatigue life of cement treated crushed rocks is one of the most complex concept in pavement engineering. From the testing regime, structural model and finally to the measurement criteria, there are a multitude of variables that can affect the fatigue response of the material. In asphalt testing, the four point fatigue bending test has gained general acceptance as a material characterisation tool capable to predict the fatigue life of asphaltic pavement layers. Its applicability to cemented basecourse materials is however arguably uncertain and widely untested. A laboratory regime which includes flexural beam testing and the four point beam fatigue test is thus undertaken. The flexural beam test investigates the flexural behaviour of cement treated crushed rocks under static loads, while the four point beam fatigue test seeks to extend the results into the fourth dimension - time. The four point beam fatigue test is completed by varying the mix design and loading frequency. The paper presents the challenges and results achieved from the test.
