Roadstone Duraflex is a Hi PSV aggregate surface course material. The aggregate composition and mix design gives it its inherent strength characteristics and increased resistance to rutting over and above that seen with Hot Rolled Asphalt. Duraflex is a highly durable material with its surface texture meeting the requirements set out by the NRA. The name was appropriately chosen to encompass both the durability and flexibility of the mix providing the customer with a long lasting product. It is primarily used for road surfacing for National and Non-National roads and urban streets
