Abstract
The increasing volume and speed of vehicular traffic on the highways today has necessitated studies concerning the development of safer roadways. Since sliding and skidding are of major concern, the surface texture has become the target of considerable research. To this end, a study was conducted to determine which of four concrete finishes under study, exhibited the best surface "toughness", as a function of the change in the surface texture depth, and wearability, as a function of the ability of the surface to maintain an adequate skid resistance (as determined by the British Portable Skid Resistance Tester). Test specimens were prepared utilizing three coarse aggregate types (a siliceous gravel, a crushed limestone and a mixture of siliceous gravel and crushed limestone), two fine aggregate types (a siliceous sand and a lightweight fine aggregate), Type 1 portland cement, and an air entrainment admixture. Standard laboratory tests were performed on all aggregates to determine their properties.
