FRICTIONAL RESISTANCE OF PAVEMENTS

This publication is a final report on an HP&R Part II multi-year research project designed to study frictional variation of roadways in the State of Maine. Specifically, the report addresses the magnitude of frictional fluctuation, both transversely and longitudinally. The effects of time on frictional characteristics and the effects of varying amounts of water during testing. Climatic parameters were also monitored during the study in an attempt to establish a relationship in terms of influencing frictional behavior. The results indicate that frictional fluctuations are relatively uniform over the entire wearing surface. The overall statistical average, at 95 percent probability, of the error around the mean of the individual locations of transverse sections was plus or minus 4.4 FN compared to plus or minus 4.7 for the longitudinal test sections which dealt with only the wheelpaths. Climatic variables which included pavement and air temperatures and accumulative rainfall five days prior to testing did not provide any significant correlation with frictional resistance either singularly and/or collectively. Long-term frictional behavior profiles were obtained on 35 wearing surfaces. The results indicated slight reductions in the frictional levels over a 10 to 11 year period. However, the frictional levels are still considered excellent, indicating an overall excellent resistance to wear. Significant variations in test water film thickness (25 percent lower to 50 percent higher) from the recommended output ASTM E 274-77 produced negligible effects on frictional levels. (FHWA)
