A laboratory study of the influence of multiple axle loads on the performance of cement treated material: interim findings
A laboratory investigation of the effects of different multiple-axle load groups on the performance of cement treated materials was conducted. In the Austroads flexible pavement design process the performance of cement treated materials is expressed as their resistance to flexural fatigue due to application of repeated loads. The flexible pavement design process considers these materials to be the most sensitive to changes in load magnitude. Using samples extracted from a test pavement, the study used an established laboratory test process for assessing the flexural modulus and fatigue characteristics of cement treated materials. Simulations of multiple-axle loads were applied during the tests, and the relationship between fatigue performance and load level for each simulated load shape was determined. The high stiffness of the materials, and the variable nature of the samples hampered the drawing of conclusive findings. Additional analysis and limited laboratory testing are recommended.
