NATIONAL PRIMARY ROUTES: SKID RESISTANCE (1981)
The authors discuss skid resistance measurements on national roads in Ireland and the presentation of the results, and examine the factors causing surface deterioration. It was found that the principal factor is the volume of heavy good traffic, and a mathematical expression is derived expressing this relation. The cost of improving the skid resistance of primary roads is evaluated for a critical level of 40 sfc (sideways friction coefficient). Costs are also shown for the case where the level chosen is 50 sfc. The cost of putting each national primary route into a satisfactory condition is based on an estimate for surface dressing of per square meter. (TRRL)
