Book Description
This paper reports the results of a laboratory test program conducted to study the variations of microtexture-related skid resistance of concrete materials with moisture condition, measurement temperature, and surface polishing. The materials used for concrete pavement construction in Singapore were studied. Surface wetting was found to produce a surface-wet frictional resistance considerably lower than the initial surface-dry value. However, neither the surface-wet nor surface-dry measurement was affected by the degree of moisture saturation of the materials tested. Surface temperature had a strong influence on the results of surface-wet tests, but not the surface-dry tests. The temperature-dependent variations was highly correlated to either measurement temperature or viscosity of water, always showing a coefficient of correlation exceeding 0.94 in absolute value. Polishing had the effect of reducing both surface-wet and surface-dry resistance. However, cement mortar specimens were found to respond differently from granite and steel slag aggregates due to differences of their surface wear behaviors in the process of polishing.
