Asphalt-Rubber Chip Seal (SAM and SAMI) applications have been “Main Stream” since 1985!

Asphalt-rubber binder and asphalt-rubber pavement preservation systems have been utilized by various city, county and state DOT’s since the early 1970’s. After years of consistent use and verified long term performance asphalt-rubber systems have become a standard for many of these agencies. This use pattern is especially true in Arizona and California as agencies in these states have established their own standard use criteria and continue to include asphalt-rubber systems in their pavement preservation efforts.
