Scrub Seal Requirements

Scrub seals bridge the gap between when chip seals are no longer effective and performing a mill and fill asphalt overlay is too expensive for the current budget. The expectation is that by employing a simultaneous apply and scrub method, one can eliminate mass cracking and improve the quality and durability on roadways in high distress. Scrub seals are at their best when the correct site selection is employed and best practices are followed. Scrub seals are able to extend the life of a severely distressed roadway by roughly 6-7 years.
