Abstract
A method for applying a high friction surface roadway treatment and composition used therein is disclosed. The method comprises the steps of: providing a binder composition, comprising: 10-99.9 wt. % of a resin; 0.1-70 wt. % of an elastomer; heating the binder composition to a sufficient temperature to obtain a molten binder composition; applying a layer of the molten binder composition; and applying a layer comprising aggregate having a nominal maximum size of at least 1 mm, and an embedment depth of at least 30% in the molten binder composition layer. The resin is selected from hydrocarbon resins, alkyd resins, rosin resins, rosin esters, and combinations thereof.
