Crack sealing is the primary target in a pavement maintenance program. If done correctly, it can add 5-7 years or more to a pavements life cycle. Crack sealing is the preventative measure used to extend and maintain the life of our roads. It’s one of the most effective ways to keep the roads safe from weather related issues. The main objective of crack sealing is to keep water out of the road – helping to avoid potholes and erosion.
Proper application is essential for this process. Studies indicate that the longest lasting method is performed in 3 steps:
1. Prep the Crack with either a router or random crack saw. This opens up the crack, creates a reservoir and preps the edge for better bonding. Rout or Saw? The most common approach is Saw Concrete, Rout Asphalt.
2. Clean the crack with dry, clean compressed air or for the best results, use a Heat lance. A heatlance removes not only dirt but moisture and vegetation. The heat lance also heats the old surface which helps in bonding with the new sealant.
3. Seal the crack with a quality Polymer modified brand name rubberized hot-pour sealant. Hot-pour sealant is proven to last up to 10 times longer the cold applied products in flexible pavements.
