Eastern Region HMA Conversion Chip Seal - Complete November 2011

To preserve the roadways and to improve the driving surface, a Bituminous Surface Treatment (BST), also known as a chip seal, was applied. It is a flexible, protective surface of asphalt emulsion and gravel that is applied to existing or repaired pavement.

How You Benefit
Dollar Sign Glyph Economic Incentive
The chip-seal layer preserves the underlying roadway structure thus avoiding the high-cost of rebuilding the highway.
