Safety

Advantage 73

Safe in the dry

By selection of aggregates with the correct Polished Stone Value (PSV) and Aggregate Abrasion Value (AAV), the surface properties of the pavement can be tailored to provide excellent dry skid resistance. A well maintained pavement provides excellent transverse and longitudinal evenness. The Swedish Road Institute1 highlighted that variations in evenness can lead to greater accident risk. Smooth and even asphalt pavements make safe roads.
