CORRELATION OF DATA FROM TESTS WITH SKID-RESISTANT TIRES

A standard test tire is generally used for skid resistance testing. The American Society for Testing and Materials (ASTM) Committee on Skid Resistance has recently adopted a new standard tire (ASTM E 501) to replace the first standard tire (ASTM E 249). The new tire is somewhat larger than the first tire and has a bias-belted construction instead of the bias-ply construction of the first tire. The Federal Highway Administration has conducted a test program to establish a correlation between skid resistance measurements of these two tires. A large-scale field test program was held at the Texas Transportation Institute and was supplemented by a small laboratory study at the Tire Research Facility of CALSPAN Corporation. A range of values for the major variables in skid-resistance testing was used. These included four different pavements, three speeds, two water film thicknesses plus some dry tests, maximum and minimum tire groove depths, and, to the degree possible, low and high temperatures during testing. The results show that both tires respond in a similar way to changing test conditions but that tire ASTM E 501 is expected to measure about 4 percent higher than tire ASTM E 249 under standard test conditions at 64 km/h (40 mph). Similar conclusions hold for dry pavements although the difference is somewhat greater. Effect of groove width, which was too narrow in the first production batch but was rectified, has been found to be insignificant under the stated test conditions. /Author/
