SKID RESISTANCE MEASUREMENT TESTS AT THE FHWA EASTERN FIELD TEST CENTER

The measurement of the skid resistance of highways, under wet weather conditions, is part of the Federal Highway Administration (FHWA) skid accident reduction program. To standardize and to improve the precision of the measurements, the program includes national and regional reference systems to which the highway measuring systems may be systematically related. This report describes evaluation tests conducted at the FHWA Eastern Field Test Center (EFTC) which included the use of the Eastern Area Reference System (EARS) and the Interim Reference System (IRS) maintained by the National Bureau of Standards. The performance characteristics of the EARS, its subsystems and a correlation equation between the EARS and the IRS are presented. A method of quantifying sources of dispersion is applied to the measurements made by the IRS on the EFTC reference surfaces. Recommendations for modifications to the EARS, the test procedures, and EFTC facilities are made.
