The goal of the Town’s annual crack sealing program is to extend the life span of the existing roadway. Cracks naturally develop in asphalt due to oxidation and pavement deterioration. Crack sealing is a necessary maintenance procedure in order to prolong the life of a roadway. Crack sealing prevents excess water from penetrating the roadway surface and migrating into the sub-base material, which is a major cause of pavement failure.
The 2021 Crack Sealing Contract has been awarded to Superior Sealcoat, Inc. of Willington MA. This contract includes 31 streets comprised of approximately 11.5 miles of roadway. Construction will be commencing throughout the summer months, with all streets being completed by early fall.
Scope of work
First all cracks will be cleaned to remove vegetation and other impediments to crack sealing. Cracks are then sealed using hot-applied rubberized joint sealant, and a light aggregate material is then applied to the hot rubber to improve adhesion to the pavement surface.
