Pavement recycling by cement stabilisation - ensuring maximum value from limited funds

Old and deteriorating flexible pavements can be quickly and economically rehabilitated or upgraded by the process of cement stabilisation of the existing material. In this way the existing material is effectively recycled. The process has application to the upgrading of shoulders or individual lanes as well as the all of the pavement across the carriageway, to fully rehabilitate the existing road or to form a new sub-base for reconstruction or overlay. The process of recycling flexible pavements by cement stabilisation has been developed by field practice and experience over the last twenty years or so and is well supported by several documented case studies. The process yields a major service life extension to the pavement typically equivalent to at least 75 per cent of the normal life expectancy of a flexible pavement at 50 per cent or less of the cost of full construction. This has been confirmed by documented case studies over the last decade in at least four States. This benefit to cost ratio confirms the economic viability of the process which allows about twice the length of road to be rehabilitated within a given budget compared with the cost of rebuilding the road.
