Cold In-place Recycling (CIR) and Cold Central Plant Recycling (CCPR) are two paving techniques that are experiencing increased use as agencies strive to find cost effective, sustainable solutions to rebuild the national roadway infrastructure without compromising performance.
The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 363: Construction Guidelines for Cold Central Plant Recycling and Cold In-Place Recycling details the development and production of proposed AASHTO Construction Guide Specifications for the application of CIR and CCPR that agencies can adjust for local conditions and environment when appropriate.
Supplemental to the document is a presentation on training materials.
