What is Stone Mastic Asphalt?

Stone mastic asphalt is a thin yet resistant asphalt surfacing mix with very good rut resistance properties and superior durability. It can be used as a base course mix for all sophisticated building needs and is primarily used for heavily trafficked roads, but it can be used for all types of pavements. It can be used in the Surface and Binder layers of a pavement. The product is a blend of a high proportion of single size coarse aggregate, plus fine aggregate, filler and binder.

Mastic asphalt is waterproof and contains practically no voids. It has three main characteristics:

• it can be poured when hot
• it is waterproof
• it has good wear resistance

Mastic asphalt is used for covering terasses, car parks and pavements, urban roads, public facilities, waterproofing engineering structures and sound insulation.
