PAVEMENT THICKNESS DESIGN FOR NO-FINES CONCRETE PARKING LOTS

A uniformly graded coarse aggregate and a cement-water paste comprise no-fines concrete. No-fines concrete is beneficial in areas that receive frequent or excessive rainfall because of its excellent drainage properties. This paper discusses thickness design of no-fines concrete parking lot pavements. Based on its engineering properties, traffic conditions, and subgrade characteristics, a determination about thickness of no-fines concrete pavements is made. Two design procedures were used for the thickness evaluation of no-fines concrete parking lots--American Association of State Highway and Transportation Officials (AASHTO) and Port Cement Association (PCA). Laboratory results indicate that if proper proportioning and densification occurs, no-fines concrete can be successfully employed as a surface paving material for parking lots. The thickness design tables reveal that the PCA design procedure is more appropriate for thinner pavements, while AASHTO yields a more conservative outcome for thicker pavements. Both design methods offered similar thickness results for intermediate traffic categories.
