• DeAngelo Contracting Services’ HFST application reduces stopping distances by up to 40%

• Up to a 90% reduction in fatalities and serious injuries after its installation

• Full lane width treatments can be applied in hours, with minimal impact to traffic

• Monitoring of mil thickness of the resin binder, volume and spread rate of the bauxite aggregate, ambient and pavement temperatures for a safe and accurate specification compliance requirement

• Low in cost compared to geometric improvements
