Abstract:

This research project evaluated the effect of blending Vanport limestone and other aggregates on the frictional surface characteristic properties of constructed trial road surfaces. The study undertook the evaluation of the performance of different mortar fractions and aggregate concentrations to determine the effect of coarse aggregate usage in the top mortar layer on pavement friction performance, as well as the effect of the substitution of different aggregates in place of Vanport limestone. The project developed a test matrix to evaluate the effect of the changes in these factors on portland cement concrete using state-of-the-art laboratory test equipment for assessing surface characteristics and using accelerated wearing for the evaluation of long-term pavement surface performance.
