111 The literature review documented information about pavement design, mix designs, performance testing, service life, cost savings, and environmental benefits. The agency survey, discussions with current and former agency staff, and a review of agency reports provided information about project selection, construction procedures and practices, and barriers to increased use of cold recycling.

112 Practice and Performance of Cold In-Place Recycling and Cold Central Plant Recycling Agency Survey and Case Examples According to the survey responses and interviews, most cold recycling programs pave less than 50 lane-miles per year. Cold recycling is frequently used on roadways with annual average daily traffic under 10,000, but more experienced agencies use cold recycling on roadways with AADTs between 10,000 and 25,000.

Conclusions 113 Adequate curing of the cold recycled mix needs to occur before placement of the final wearing surface. This is commonly done by defining maximum allowable moisture content or by setting a limit on the time between recycling and overlay placement.
