A STUDY OF VARIABLES ASSOCIATED WITH WHEEL SPIN-DOWN AND HYDROPLANING

An evaluation of the wet weather properties of a portland cement concrete pavement and a bituminous surface treatment is presented. The study uses wheel spin-down as the criterion and considers the effect of water depth, tire inflation pressure, tire tread depth and wheel load. A hydroplaning trough 800 ft. long, 30 in. wide and 4 in. deep was used in obtaining the data. The results indicate that the bituminous surface treatment requires a considerably higher ground speed to cause spin-down than the concrete pavement. Further, even though a single critical speed does not exist for the range of variables selected, a reduction of speed to 50 mph is recommended for any section of highway where water can accumulate to depts of 0.1 inch or more during wet weather periods.
