Rosphalt® is a dry black polymer additive that is added to the asphalt mix at the asphalt plant. When combined with the heated aggregate and liquid asphalt, the result is a highly polymer-modified asphalt mix that will create a waterproof, rut and crack resistant wearing course that will also provide excellent resistance to flexural fatigue.
Royston® Sheet Membranes are manufactured using prefabricated reinforced laminates consisting of impregnated fiberglass, and a high strength inner core sandwiched between two layers of polymer modified bitumen adhesive. The reinforced rubberized bitumen-based membranes provide excellent tensile strength and puncture resistance.
