Why seal asphalt cracks in the winter?
Crack Sealing is your first defense against significant pavement deterioration brought on by wet weather and temperature changes. Expansion and contraction is most damaging during the winter. Crack fill can be applied even in cold weather as it is heated to 275 degrees prior to installation.
Crack fill, a mix of asphalt and rubber is installed in cracks between 1/8” and 1” wide. It seals cracks to prevent water from damaging the sub base. It also serves to create a more uniform surface for future seal coating. Properly applied seal coating will fill cracks less than 1/8” wide.
Integrity uses Spec Plus, an upgrade crack fill product from Neyra Industries. It contains higher rubber content for improved bonding and expansion. Spec Plus includes UV inhibitors to protect against damaging sunlight. It is considered non-hazardous by the EPA and designed to expand and contract with the asphalt it is protecting.
Crack filling preserves the pavement adjacent to the cracks; preventing sand, stone, and dirt from making its way into open cracks causing compressive stresses. Crack filling also extends pavement life by minimizing crack expansion.
Proper attention to cracks prevents problems from spreading. Pavement repair in the early stages of deterioration pays dividends later by delaying costly asphalt repairs.
Periodic and preventative maintenance is the key. A few hundred dollars invested each year in crack filling could save you thousands in future repairs.
Areas breaking up (alligatoring) with loose blocks that can be dislodged requires removing damaged asphalt, installing compacted base as required and replacing with hot mix type D asphalt. A section of pavement with large connecting cracks requires asphalt replacement.
