Project description

The curing of concrete is widely recognized as a critical step for achieving high-quality long-lasting concrete pavements. While the most common curing practice is the application of mem-brane-forming curing compounds, the compound specifications, including application rates and the quality control/quality assurance (QC/QA) practice, differ among state departments of transportation (DOTs). The timing of the curing application—which is critical to the success of the curing process—also differs among state DOTs. State DOTs may also adopt additional curing measures during adverse weather conditions. The objective of this synthesis is to document state DOT practices for curing pavement concrete including procedures, materials, application rates, timing, QC/QA procedures, and specific measures adopted when paving under adverse weather conditions. Information will be gathered through a literature review, a survey of state DOTs, and follow-up interviews with selected agencies for the development of case examples. Information gaps and suggestions for research to address those gaps will be identified.
