The City of Andover has an annual maintenance program that it completes on local city streets and parking lots. One of the maintenance procedures is crack sealing. Crack sealing is completed approximately 2 years after a road has been paved, or on an approximate 10 year rotating basis.
What is Crack Sealing
Crack sealing involves routing and cleaning new pavement cracks so they are free of weeds, dirt, debris and other incompressible material. The cracks are then filled with a sealant and covered with a paper product to reduce tracking of the material. Crack sealing prohibits water and incompressible material from entering the pavement structure, which in turn extends the life of the street. This work is contracted out to an independent contractor, but is supervised by city staff to ensure that the work is completed according to city specifications.
