DEEP-LIFT RECYCLING OF GRANULAR PAVEMENTS

Since 1991, the Roads and Traffic Authority NSW has been trialing deep-lift recycling of granular pavements on heavily trafficked pavements in rural NSW. The trials have established the capability of existing equipment to recycle pavements to 300 mm or more in depth, incorporate the cementitious binder and adequately compact the pavement to meet the pavement design criteria. These trials have established the cost savings that can be achieved and have also trialed a draft quality assurance specification for thework. The trials have shown that there are substantial productivity benefits to be gained in the rehabilitation of heavily trafficked rural pavements using these techniques. The paper presents the results of the trials held to date, a summary of the guidelines for deep-lift recycling of granular pavements and a summary of the quality assurance specification that has been developed.
