Description
| Summary: | Tennessee has been continuously engaged in skid resistance and corrective action research since 1952. A new program was initiated in July 1970 as a specific effort of inventorying the present skid resistant level of the State's primary highway system. The skid resistance level is measured with the University's two-wheel skid trailers that essentially meet the requirements of ASTM designation E 274 using the standard ASTM E 249 tire. The skid tests are performed on wetted pavements at a constant speed of 40 mph. Tests are conducted at intervals of approximately one-half mile or less in the inner wheel path of both lanes of the pavement. To date, 66 counties of the 95 counties within the State have been surveyed. This amounts to about 48 percent of the total rural highway mileage. For each test section base data on roadway goemetry, pavement surface characteristics, pavement type and date of construction, and the length of the test section are recorded for future evaluation
