Project description

The Nebraska Department of Roads (NDOR) began to explore various sealer applications for pavements susceptible to Alkali Silica Reaction (ASR), this research was launched with the cooperation of the City of Lincoln to prevent deterioration to those pavements that have not mitigated ASR. NDOR occasionally uses concrete sealers on bridge deck applications; however, not for concrete pavements. Therefore, this investigation will analyze if concrete sealers may be used in the future as a preventative maintenance tool in order to delay deterioration in pavements that are susceptible to ASR. This is the first evaluation of concrete sealers for PCC pavements performed by NDOR Materials and Research. The most common concrete sealers are film formers, such as acrylics and thermoplastics; and penetrating sealers including silicones, siloxanes, silanes and silicates. All Types will be studied in this investigation.
