摘要：	The objective of this project was to evaluate existing literature regarding the practice of pavement crack sealing and crack filling. Crack sealing and crack filling consist of the placement of specialized materials into the cracks in pavement surfaces in order to prevent the intrusion of water and foreign objects. It has been suggested that this process extends the life of a pavement surface and can therefore reduce an agency's pavement replacement and rehabilitation costs. The following topics were identified in previous studies, including some conducted in Connecticut, and are discussed in this report: benefits of crack treatment; roadway evaluation; procedures and equipment selection; material placement; treatment materials evaluations; and traffic safety issues. Overall, the previous literature suggests a great deal of variability in opinion regarding the benefits of crack treatment. There is much inconsistency with results from previous studies with respect to location, circumstances and materials employed.
