The Mechanical Properties of Foam Asphalt Mixture
The mechanical properties of foam asphalt mixture are investigated, including indirect tensile strength (ITS), moisture resistance, rutting resistance and fatigue resistance. The test results indicate the 40°C3d curing mehod can stimulate the 30d or 60d natural environment temperature (25°C) curing procedures, which can quickly evaluate the long term ITS of foam asphalt mixture with cement or without cement. Cement can obviously improve the ITS, moisture resistance and fatigue test. The paper recommends proper cement content of foam asphalt mixture should be in between 1.5% to 2.5%.
