Project Description
PPC HFST is designed to increase friction on the roadway surface and minimize crashes. California State Route 17 is a mountainous four-lane roadway that serves 60,000 vehicles daily.
High Friction Surface Treatment (HFST) is routinely used to restore and increase friction in critical areas that are prone to crashes. On Highway 17 near Santa Cruz, CA, one such dangerous area exists, nicknamed the “deadly” Laurel Road Curve. This installation utilized Kwik Bond’s Polyester Polymer HFST resin with a broadcast of Calcined Bauxite aggregate. Two courses were installed because the asphalt pavement was an open-graded friction course (OGFC). PPC HFST is designed to increase friction on the roadway surface and minimize crashes.
