Abstract

RESULTS on an evaluation of two sets of full-scale experimental concrete test sections are summarized. Eighteen experimental concrete finishes were evaluated in terms of skid resistance under standard trailer water conditions and under simulated rainfall conditions. In addtion the changes in texture depths and skid values with time were measured.

RESULTS indicate that (a) texture depths of 0.15 cm (0.06 in) or greater can be constructed easily and economomically with 0.32-cm (1/8-in) metal tines spaced closer than 1.27 cm (1/2 in) apart; (b) under normal traffic conditions, all concrete textures can be expected to wear down approximately 25 to 35 percent during the first half year and then remain relatively unchanged for a prolonged period; (c) skid measurements made under standard trailer water conditions may not be indicative of real-life conditions in wet weather; (d) low skid values could be obtained in almost any rainfall in which the pavement is completely wetted regardless of texture; and (e) under simulated rain condition, deep transverse texturing will result in the greatest improvement in skid values.
