Comparison of Hot Poured Crack Sealant to Emulsified Asphalt Crack Sealant: A Summary
An important element of pavement maintenance is crack sealing and filling. Hot pour materials are the most commonly used, providing good performance in most cases. The performance history and costs of cold pour asphalt emulsion crack sealants are not well known or well documented in comparison to those of hot rubber crack sealants. This report concludes a four-year research project intended to compare the cost-effectiveness, performance, and life-cycle costs of hot pour rubber asphalt crack sealant and cold pour asphalt emulsion crack sealant. A survey of Texas Department of Transportation (TxDOT) districts and state DOTs was conducted on crack sealants, and the long-term performance of seven different sealants were monitored. Installation and lifetime costs were analyzed for the different types of sealants, and recommendations were made to modify TxDOT specifications.
