Research

The objective of this study is to determine if the scrub seal is more cost effective than microsurfacing, chip seals and the 1" hot mix overlay. Scrub seals were placed at 10 different locations and reviews of each section were made to determine the usefulness of the seal. Most of the scrub seals are very promising although it has been determined they should be limited to areas of less than 7500 ADT. Most of these scrub seals are about 1 year old and we are hoping to get a life span of 3 to 4 years from them.
