Mix design of bitumen-stabilised materials – South Africa and abroad

The need for sustainable road infrastructure maintenance has led to a significant growth in pavement recycling and bitumen-stabilisation technology. This, in turn, has created a need for robust mix design and pavement design procedures for bitumen-stabilised materials (BSMs), using either foamed bitumen or emulsified bitumen binders.This paper outlines the research developments in the field of BSM technology and testing and their link to a...
