This method covers procedures for preparing compacted asphalt samples and conditioning the samples to determine the potential of moisture damage using hydrostatic pore pressure. Conditioned sample can be tested for tensile strength, to determine the change in bulk specific gravity or percent air voids and/or change in percent saturation.
It is important for design and quality control of asphalt pavements to test asphalt materials for moisture sensitivity by creating pore pressure. Pore pressure is one of the major causes for moisture damage on pavements. This practice provides the industry with a conditioning method that better simulates traffic affect on wet pavements.
