PROCESS APPROACH TO IN SITU CEMENT STABILISATION AS A METHOD OF REHABILITATION OF FAILED PAVEMENTS . 28TH ARRB REGIONAL SYMPOSIUM, TOOWOOMBA, QUEENSLAND. PROGRAM AND PAPERS

Substantial cost savings of 50 per cent plus from the conventional reconstruction process has been achieved by the Brisbane City Council in recent years by using a highly streamlined in situ cement stabilisation process for the rehabilitation of failed pavements. Engineers are increasingly faced with the challenge of either large scale reconstruction programs or upgrading existing pavements to meet current serviceability requirements, and to do it as cost effectively as possible. One of the techniques adopted and developed by the Brisbane City Council is the streamlined process of in situ pavement stabilisation. The Brisbane City Council carried out its first pavement rehabilitation trial of failed gravel pavements using the in situ cement stabilisation process in 1967. It was not until 1982 that a substantial stabilisation program was implemented. Initial results were encouraging with cost savings of approximately 35 per cent below conventional reconstruction processes. Since that time, with the continuing refinement of the process further costs savings of 50 per cent and higher are being achieved. This paper reviews the developments that have occurred and the methodology adopted by the Brisbane City Council in achieving an increased strengthening of existing pavement structures coupled with substantial cost savings (A).
