DESIGN PREDICTION OF PAVEMENT SKID RESISTANCE FROM LABORATORY TESTS

The objective of this research has been to develop and refine methods for pre-evaluating aggregates and paving mixtures so that predictions can be made covering skid resistance properties of proposed and in service pavement types. The equipment used during the testing included a K.J. Law Locked Wheel Pavement Friction Tester, a British Portable Tester, a North Carolina type small wheel circular tack wear and polish machine built by KsDOT personnel. a device for plotting a linear traverse profile of a pavement sample, and stereophotography equipment. A usable correlation was established between the field testing using the data from the British Portable Tester and the Locked Wheel Pavement Friction Trailer at speeds of 40 and 55 mph. To extend this correlation, core samples were extracted from the Locked Wheel Tester Skid Path and were subjected to wear on the small wheel circular tack with periodic surface friction testing using the British Portable Tester. The final step was to remix and remold the cored pavement samples or make samples with new materials to obtain an "as new" surface and again subject these samples to wear on the small wheel circular track with periodic testing using the British Portable Tester to find the British Pendulum Number (BPN). Other segments of the project included efforts to correlate Stereo-Photography Number (SPN) vs. Locked Wheel Pavement Friction Tester SN, Stereo-Photography Number (SPN) vs. BPN on the wear and polish machine and Linear Traverse Number (LTN) vs. BPN on the wear and polish machine. Some research was conducted with various chat (chert)/limestone mixtures in an attempt to establish a blend offering good resistance to skid and wear and polish. Results from the study indicate that predictions can be made of the surface friction and possibly the durability properties of pavement design by laboratory testing. (FHWA)
