Bitumen spray seals provide a simple and cost-efficient way to quickly resurface a driveway, carpark or road when compared with using asphalt or other forms of paving.
Bitumen spray sealing represents the most common form of road surfacing in Australia, providing a flexible and functional pavement product that suits an array of applications including:
Bitumen is a highly-viscous, sticky black substance derived from crude oil – it is a semi-solid form of petroleum. It can occur both naturally as well as be refined, and it is known traditionally as “pitch”. Bitumen acts as a binder for aggregate crushed rock, which together forms asphalt.
A bitumen spray seal is a thin layer of bitumen that is sprayed on top of a road surface. It is then covered with an aggregate layer, which is embedded into the underlying bitumen surface using a roller. This results in a low-cost surface solution that is waterproof, free of dust, and resistant to skids.
A bitumen spray seal is designed specifically for the traffic conditions of a road or other surface, and for greater traffic volumes, more coats are applied as required. It is also a great way to rejuvenate an existing driveway or other pavement and extend its lifespan.
The typical lifespan of a bitumen spray-sealed surface is between seven and fifteen years, depending upon usage and weather extremes.
Resealing roads and driveways with bitumen seals is an important part of periodic maintenance and restoration.
