Pavement cracks and joints are not the same. Cracks are caused by deterioration of the pavement. Obviously, pavement is best when it is first constructed. As sunlight oxidizes the pavement and seasonal temperature changes expand and contract the pavement, cracks form. Water, impurities, and debris infiltrate the cracks and continue to degrade the pavement and put the pavement’s subbase as risk.
Joints, in contrast to cracks, are not developed by deterioration but instead are built by design. Pavements are known to crack as they age, therefore joints are created when the pavement is constructed to control where cracking may occur.
Doan focuses on quality and long-term performance and therefore manufactures products that have a significant service life like hot-applied asphaltic-based crack sealant and cold-applied silicone joint sealant that have demonstrated in independent studies to provide the longest service life available.
