Abstract:This paper presents a case study for examining the in-place performance of pervious concrete in a medium-size parking lot in Denver, CO. Of interest are the surface characteristics and hydraulic properties of the concrete dependent upon the degree of deterioration. Test results include pavement texture depth, skid resistance, surface profile, infiltration, and traffic volume. A statistical approach, analysis of variance, is conducted to evaluate the distinct surface properties of various locations in the parking lot. Mutual independency between the surface texture depth and skid resistance is discussed. A practice-oriented predictive model is proposed to estimate an international roughness index of pervious concrete using a texture depth value and skid resistance. A relationship between the infiltration of the pervious concrete and traffic attributes is established. The performance reliability of the parking lot is evaluated in conjunction with critical rainfall intensity.
