REHABILITATION WORKS IN QUEENSLAND USING FOAMED BITUMINOUS STABILISATION

摘要: Adapting foamed bitumen stabilisation is considered as the most cost effective approach in Queensland to expedite rehabilitation works, especially after major flood devastation 2011. This paper presents key changes made well recent practices adapted during a road work increase return from investment. In this process, initially, designed width for subgrade lime has been modified minimize moisture entry into pavement. The dry modulus, three days soaked resilient modulus and retain were used identify suitable base material construction. addition, trail site was examine bulking effect on layer when adding secondary agent, which helped estimate exact depth stabilisation. A few innovative techniques such two-layer compaction effectively condense stabilised subgrade, improve quality of outcome also highlighted.
