Council undertakes periodic bitumen resealing work on our sealed road network to rejuvenate and extend the life of roads and streets. The bitumen resealing process consists of spraying a thin film of bitumen across the road surface, and then adding small stones on top of the bitumen film. This forms a durable waterproof dust free layer on top of the road, can improve the skid resistance of the road surface, and reduces the occurrence of potholes and cracks forming. Typically, the useful life of a bitumen seal is 10-15 years, after which time bitumen resealing should be undertaken. A copy of the Bitumen Reseal Program - 2020/21 is available here.
