FRICTIONAL RESISTANCE OF PAVEMENT SMOOTH VERSUS RIBBED TIRES

This publication is a final report for an HP&R, Part II Federally sponsored, multi-year research project. The report addresses the relationship of frictional values obtained with the ribbed (E-501) and the smooth (E-524) test tires. The equipment used in the study was in conformance with E-274 specifications and all values were obtained at 40 mph. All wearing surfaces used by the Maine Department of Transportation were incorporated in the study but the emphasis was placed on the three primary types; "C" mix, a dense graded bituminous mix, "G" mix, a coarse open graded bituminous mix and Portland Cement Concrete. The results indicated that the coarse open graded mix was greatly superior to all other pavements in minimizing frictional loss resulting from smooth tire testing. On all pavement type there were large variation in the percent of frictional loss from the use of smooth tires. Therefore, predicting frictional levels for either the smooth or ribbed tires based upon values obtained with the other cannot be considered valid. (Author)
