The outstanding success of Bitumen-rubber (B-R) asphalt over the past 15 to 20 years in South Africa has revived interest in this product in recent years. This success became prevalent in 1998 with the report on the 12-year service life of bitumen-rubber asphalt on the Buccleuch Interchange [Potgieter et al. 1998].
Overview In June 2024 South Africa's Bitumen and asphalt exports accounted up to ZAR28.3M and imports accounted up to ZAR8.34k, resulting in a positive trade balance of ZAR28.3M. Between June 2023 and June 2024 the exports of South Africa's Bitumen and asphalt have increased by ZAR10.8M (61.9%) from ZAR17.5M to ZAR28.3M, while …

Bitumen-rubber asphalt (BRA) has been used successfully in South Africa since its introduction in the early 1980's. The early mixes were produced using the 'dry' blend method whereby the rubber crumb was added as filler to the aggregates in the hot mix asphalt manufacturing process. The 'wet' blend method has subsequently
