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.

A method for treating a roadway with a high friction surface, the method comprising the steps of:
- providing a binder composition, comprising:
- 10-99.9 wt. % of a resin, wherein the resin is selected from hydrocarbon resins, alkyd resins, rosin resins, rosin esters, and combinations thereof;
- 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 on the roadway for a thickness of at least 40 mils;
- and
- applying a layer comprising aggregates on top of the molten binder composition, wherein the aggregates have a nominal maximum size of at least 1 mm,
- wherein the layer comprising aggregates is applied on top of the molten binder composition layer within 60 seconds, for the aggregates to be embedded to a depth of at least 30% in the molten binder composition layer.
