DECAY OF TINE-TEXTURED GROOVES IN RIGID PAVEMENTS

This is the second and final report on a project to determine the effectiveness and durability of tined grooves on portland cement concrete pavements. This report updates and reinforces the statistical relationships between friction decay and traffic volume, and between texture wear and traffic volume after the passage of 2 years of additional traffic. Based on the initial groove depth requirement of 0.050 in. as determined in the first report, and the updated mean groove wear rate of 0.010 in. per million vehicle passes, the current tining specification minimum of 2/16 in. should provide life-long friction for about 54 percent of New York's rigid pavements. If the intial requirement were 3/16 in., 78 percent of roads would have adequate friction. (FHWA)
