NC Department of Transportation developing new method to reduce hydroplaning

RALEIGH, N.C. (WTVD) — The North Carolina Department of Transportation and university research partners are developing a new method to enhance skid resistance along the state’s highways.

The DOT said a ” shotblasting ” strategy is being evaluated and will generate more texture on the pavement surface to allow for better drainage during wet weather and enhance frictional force between the tire and pavement.

According to the department, the shotblasting machine collects dust and contaminants during the process and does not use chemical products or wastewater.
