Description	Since its first introduction to South Africa bitumen-rubber has found increasing acceptance in various rehabilitation projects. This material has been used successfully in the prevention of reflection cracking on cracked asphalt and concrete pavements. Although bitumen-rubber has to date been used mainly in stress-absorbing membrane single seals, the use of rubber in asphalt mixes has gained growing acceptance. The study was conducted in conjunction with a rehabilitation project on the N2 Freeway between Cape Town and Somerset West, which was completed in November 1986. This project included a 40-mm bitumen-rubber asphalt overlay.
