LABORATORY TESTING TO PREDICT FRICTIONAL PERFORMANCE

Aggregate properties, when properly determined in the laboratory, can be effectively utilized to predict the frictional performance of bituminous pavements. Recent research in friction aggregate testing has shown a strong correlation between the laboratory and field friction measurements. The effectiveness of the correlation is greatly dependent upon the user's understanding of the purposes and limitations of the test procedures. Refinement of these procedures is needed in order to better relate the aggregate properties to the macro-and micro-texture, as well as understanding how these parameters relate to the overall pavement friction. To attain a desired level of pavement friction, it is essential to maintain a necessary balance between the micro- and macro-texture, as it may be represented by polish value, 5-cycle magnesium sulfate soundness, and differential wear test results. Pavement friction prediction and aggregate qualification should be drawn from the results of adequate laboratory and field procedures.
