Duralayer® Multi is a dense material design for single layer applications. It is suited to a variety of asphalt surfacing applications where a low textured and deformation resistant one layer treatment is required.
Duralayer® Multi was designed following a request from a local authority for a cost-effective, single layer solution. It utilises locally sourced aggregates and is suitable for a variety of applications including major roads, rural roads, housing estates, car parks, caravan parks and trench reinstatements.
The product’s unique design creates a low surface texture and controlled low air voids. This resists water ingress, providing a more durable surfacing solution. Duralayer® Multi doesn’t segregate like traditional materials, making it also ideal for handlay applications.
Duralayer® Multi is available in 20mm, 14mm, 10mm and 6mm nominal sizes and is laid using conventional paving equipment in line with BS 594987.
Duralayer® Multi+
