Most Crack Sealing operations can be conducted year-round; however, they often take place during cool or moderately cool weather (2 to 13 ℃). At these temperatures, cracks are mostly or completely open, and more material can be applied.
Crack Sealing operations can be preventive or routine in nature, depending on the highway agency’s approach to treating the cracks. Like sealing operations, preventive Crack Sealing maintenance should be conducted shortly after non-working cracks have developed adequately. Depending on the type of cracks to be filled by Crack Sealing Machine, this may occur as early as between 4 and 8 years after construction or resurfacing.
Durable filler materials should be used to reduce the number of repeat applications. By filling cracks shortly after they are fully developed, further growth is delayed.
