VICROADS EXPERIENCE WITH FOAMED BITUMEN STABILISATION

Foamed bitumen stabilisation is an in situ pavement recycling technique to extend the life of a distressed pavement. Fresh, foamed bitumen is added to existing pavement materials to form a bound layer. This paper documents VicRoads' experience with foam bitumen stabilisation trials conducted on three major roads in Melbourne in 1993. Two of the trials were on heavily trafficked arterial roads, where major rehabilitation of flexible granular pavements was required and a third trial was conducted on a freeway where pavement strengthening was needed to convert the shoulder into an additional traffic lane. This paper discusses the requirements for initial pavement investigation; field and laboratory testing and design criteria; construction aspects of the field trials, such as details of the siteworks and traffic staging; and a recommended specification for future foamed bitumen stabilisation works based on experience gained from the trials.
