Asphalt surface treatments (AST) are a cost-effective pavement preservation technique on low-volume roads. The AST is constructed by spraying an asphalt mixture onto the pavement surface, then spreading chips of fine rock into the mixture. The chips are embedded into the surface by rubber-tired rollers, and the surface is then swept to remove excess chips.
This treatment seals fine cracks in the underlying pavement surface, which reduces pavement deterioration by preventing water from intruding into the base and subgrade of the road. This improves wet weather traction, as well as safety.
