Book Description
A correlation has been established between skid resistance measurements with the newly adopted test tire (ASTM E501) and the previous standard test tire (ASTM E249). The correlation is based on a large scale field test program, supported by laboratory tests on a high speed facility. Both tires respond in a similar way to changing test conditions, but tire E501 is expected to measure about 4 percent higher than tire E249 under standard test conditions at 40 mph. Prediction equations and the associated estimated variances are given for an all-inclusive correlation, as well as separate equations for three speeds (20, 40, and 60 mph) and separate equations for each of the four pavements used in this program. Limited tests on dry pavements also show generally higher readings with tire E501.

Book Description
This synthesis report will be of interest to pavement design, construction, management, and research engineers, highway safety officials, and others concerned with pavement friction characteristics. It describes the current state of the practice and discusses the methods used for evaluating wet pavement friction characteristics of new and restored pavements. This synthesis reviews models used for measuring and evaluating friction and texture, causes for friction changes over time, and aggregate and mix design to provide adequate friction. Also presented are construction and surface restoration practices for providing good pavement surface characteristics. In addition, considerations of noise and ride quality are discussed when compromise may be required.
