APPLICATIONS OF RUBBER-BITUMEN MEMBRANE SURFACING IN PAVEMENT MAINTENANCE --PROCEEDINGS OF THE FOURTH CONFERENCE ON ASPHALT PAVEMENTS FOR SOUTHERN AFRICA, HELD CAPE SUN HOTEL, CAPE TOWN, REPUBLIC OF SOUTH AFRICA, 12-16 MARCH 1984. VOL 1 & VOL 2.

Rubber-bitumen membranes can be used with significant cost effectiveness (typically 20 to 40 per cent savings) in pavement maintenance and rehabilitation; particularly in the repair of cracking where deformation is not a major problem. The combination of low stiffness, low temperature sensitivity and high elastic recovery which is possible with blends of synthetic or ground rubber and bitumen in a membrane results in very high stress reductions over active cracks or joints and permits the use of much thinner surfacings than may otherwise be necessary. Performance data from field studies in New Zealand and USA, and results from analytical and laboratory studies, are used to demonstrate the behaviour mechanisms and design principles involved. Guidelines are given for the use of surface membranes and full interlayers and partial interlayers in membrane-over-lays.(a) for the covering abstract of the conference see IRRD 815702.
