Public Works crews have rolled out the crack sealer to help prolong the life of streets that have been resurfaced in the last five years. Crack sealing is the process of placing an adhesive sealant into cracks on the pavement surface, preventing the infiltration of moisture and non-compressible materials into the pavement. Crack sealing can be used for cracks wider than ⅛” but not more than 1.5”, including block, edge, longitudinal, reflective, thermal or transverse cracking. It is a cost-effective pavement preservation treatment that can slow pavement’s deterioration and extend pavement life by three to five years. This method of road maintenance is typically performed in the spring or fall when temperatures at least 40 degrees Fahrenheit and when cracks are not completely open (as in winter) or closed (as in summer).
