Develop Enhanced Cold Recycling Methods and Specifications
Texas continues to use cold recycling for pavement rehabilitation and performs a significant amount of full depth reclamation (FDR). While cement remains the most widely used treatment, use of asphalt emulsion and foamed asphalt continues to grow. This project will identify and evaluate topics to strategically enhance cold recycling practices in Texas. This project will perform a comprehensive performance analysis of recent as-built projects to identify strengths and opportunities for process enhancement. For cement, this project will evaluate how cement type may influence mixture properties, analyze the Texas Flexible Pavement System (FPS) structural design assumptions based on current mix design and construction practices, and summarize methods to improve early trafficking. For emulsified and foamed asphalt, this project will develop cold-in-place recycling (CIR) applications for Texas and identify, evaluate, and recommend enhanced pavement design procedures for cold recycling with asphalt binders. This project will use all results to develop enhanced cold recycling project selection procedures, recommend updates to Texas Department of Transportation's (TxDOT’s) specifications, and develop and perform training.
