Abstract

Today, one of the most serious problems of asphaltic surfaced pavements containing a stabilised base course is the occurrence of transverse cracking in the stabilised base and the associated propagation of cracks to the surface, which reduces the effective life of otherwise structurally sound pavements. Compared to cement stabilised bases, Bitumen Treated Bases (BTBs) may be relatively more flexible and more resistant to fatigue cracking. However, although BTBs have been used as structural pavement layers for more than 40 years, research in this area has been scarce. This paper summarises the results of laboratory tests recently carried out on a BTB mix to assess its performance properties in relation to compaction and workability, strength, resistance to rutting and permeability.
