Optimization of Cement Modified Recycled Base (CMRB) Mixture Design
CMRB has been a successful reconstruction strategy for the South Carolina Department of Transportation (SCDOT), however, minimal changes have occurred to optimize the design and testing parameters or move towards performance specifications. SCDOT leads the nation in the use of reclamation and is in a unique position to lead the industry in improving the process. The current design practices focus on compressive strength and the current field practices focus on depth of treatment, moisture, and compaction, which may not be the most effective factors for assessment of durability and long term performance. The objective of this research is to review the current practices used by SCDOT in reclamation treatments and determine procedures to update that will optimize the planning, sampling, design, and testing of reclamation treatments. Variables that will be studied include chemical stabilization using cement, lime-cement blends, and lime kiln dust (LKD) in both traditional and synthetic reclamation.
