Coffs Asphalt design and construct professional bitumen driveways in Coffs Harbour. Bitumen is an excellent choice as a lower-cost alternative to asphalt or concrete. Bitumen, sometimes known as spray seal, resembles asphalt in that it is composed of hot liquid asphalt and gravel as the primary structural element. However, in contrast to asphalt, which is pre-mixed, the constituents are delivered individually and combined on-site. In addition, bitumen is nothing new; it has been used successfully to resurface roads, parking lots, and residential driveways worldwide for over a century. As a result, bitumen is a popular choice for Councils in Australia. So, contact our friendly team today and arrange a free, very competitive quote for your bitumen driveway in Coffs Harbour
TWO-COAT BITUMEN SEAL is a process whereby the surface is sprayed with bitumen which has a waterproofing effect, followed by a second coat of aggregate (or gravel). The aggregate size depends on the intended use of the surface. As there are so many different types of bitumen and spray rates, aggregate sizes are usually specified by the engineer to meet council requirements. Overall, it depends on traffic volume, life expectancy and the original surface type. A two-coat bitumen seal is an affordable alternative to brand-new paving and is ideal for longer and rural driveways.
