Abstract:

The objective was to develop and refine methods for preevaluating aggregates and paving mixtures so that predictions can be made of properties of proposed and in-service pavement types. A usable correlation was established between the field testing by 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 track with periodic surface friction testing by using the British portable tester. The final step wa to remix and remold the cooled pavement samples or make samples with new materials to obtain an "as-new" surface and to subject these samples again to wear on the small-wheel circular track with periodic testing by using the British portable tester to find the British pendulum number (BPN). Other segments of the project included efforts to correlate (a) the sterophotography number (SPN) with the locked-wheel pavement friction tester skid number, (b) the SPN with BPN, and (c) the linear traverse number with BPN on the wear and polish machine. Research with various chat (chert) and limestone mixtures shows that the blend offers good skid resistance. (Author)
