Recently published: Feasibility of Cold Central Plant Recycling Asphalt Mixtures for Airports: Task 1 Report

A recently published UCPRC research report examined whether recycled asphalt can be safely and effectively used for airport runways and developed the methods, guidelines, and training needed to make it possible. This Phase 1 study evaluated the feasibility of using cold central plant recycled (CCPR) asphalt mixtures for airport pavements, which included a literature review, laboratory and limited accelerated testing, and the development of design procedures, specifications, and training materials. The study found limited existing literature, confirmed that current FAA design software and pavement design approaches cannot adequately model recycled layers for airport conditions, and determined that new design methods and specifications were needed. As a result, test plans, FAA-compliant specifications, and just-in-time training were developed to support accelerated pavement testing and future implementation.
