Literature Review of Curing in Portland Cement Concrete Pavement
Curing of concrete has an effect on hardened concrete properties and overall long-term performance of portland cement concrete (PCC) pavement. A significant amount of research has been conducted to evaluate curing effectiveness and its effect on concrete properties. This report synthesizes the findings from the literature review, including the relative humidity measuring techniques. The most frequently measured concrete properties are strength and permeability. They are important properties; however, in portland cement concrete pavement, volume change potential affected by curing effectiveness is as important for its performance. Not much information has been found in this regard. It appears that the curing effect is confined to the surface of the pavement, which is called curing-affected zone (CAZ). The extent of this zone varies, depending on the concrete properties and curing effectiveness, with average values varying from 14 in. to 12 in. CAZ has a significant effect on the performance of PCC pavement. Further evaluation is needed to investigate the effect of curing on CAZ and overall pavement performance. Other state departments of transportation (DOTs) specifications for curing concrete pavement were investigated and all are nearly identical. They are prescriptive and method-type specifications and no compliance testing is required.
