Rugosoft (Phonic Asphalt)

Rugosoft is an asphalt type whose macro-texture is designed to lessen the noise made by passing vehicles. It is mainly used in semiurban areas to lower, as much as by half, noise levels produced by high-speed road traffic reaching the vicinity’s inhabitants. Through its unique macro-texture, Rugosoft provides greater adhesion than conventional asphalt which substantially lowers aquaplaning hazards.
