Frictional Properties of Highway Surfaces
The purpose of study was to evaluate effects of differential friction; compare experimental and standard texturing techniques of Portland cement concrete pavements; determine if Mu-Meter is capable of measuring frictional effects of grooving and develop wet pavement accident analysis system for use in Arizona. Results have shown that differential friction can cause extremely hazardous conditions for braking vehicles. There is a strong indication that differential friction may be as important in causation of wet pavement accidents as low friction levels. All burlap drag textures tested produced poor, non-uniform finishes that were significantly less durable than other textures tested. Nylon bristle broom texture produced best overall results, while magnesium fluted float produced unusual texture that definitely has merit.
