SKID RESISTANCE OF INDIANA PAVEMENTS: 1. HIGH ACCIDENT LOCATION PHASE; 2. PORTLAND CEMENT CONCRETE PHASE; 3. BITUMINOUS CONCRETE PHASE
A three-phase study was conducted using skid resistance as the unifying factor to isolate unsafe pavement surface, to select desirable aggregates, to study surface textural properties of P.C.C. pavements, and to evaluate bituminous surface mixes. The investigation found that a determination of a criterial level of skid resistance depends upon many factors. No signle skid number could be identified as a minimum requirement for safety under all existing pavement conditions. The skid testing system is not a precise enough method for isolating individual surface textural properties. Initial skid resistance, however, is directly proportional to the degree of texturing. In P.C.C. pavements, once the surface mortar is worn by traffic, skid resistance becomes a function of the properties of the exposed coarse aggregate. A significant finding of the Bituminous concrete Phase was that HAC Type B surfaces exhibit the greatest loss of skid resistance. On the other hand, HAE Type II surfaces were superior due to high initial skid values and an acceptable rate of wear. /Author/
