Asphatec surfacing system
AsphaRock
A natural aggregate finish over existing asphalt.
AsphaRock is a decorative asphalt system that incorporates broadcast natural aggregate to produce a rock-finished surface. It is intended for suitable existing pavement where aggregate color and texture are part of the architectural finish. Pavement condition, repairs, traffic, drainage, edge restraint, aggregate compatibility, and maintenance requirements must be evaluated before installation. Aggregate type, gradation, broadcast coverage, retention, detailing, and final appearance should be confirmed through a representative test area. CST supports customer projects with system guidance, sample or mockup work, installation planning, and ongoing technical support.
