Abstract:

This report describes development of an augmentation kit that will give users of the sustainment pavement repair SuPR kit the capability for in-place asphalt recycling. This type of repair has the potential for reducing not only logistics associated with airfield pavement repair, but also the airfield downtime during the repairs. The specific technologies evaluated were infrared heaters, rejuvenator products, and cement stabilization. Different variations of these technologies were combined and evaluated in the laboratory to study the best combination that would produce quality sustainment repairs in asphalt concrete pavement yielding good performance with limited construction periods. The researchers also performed a series of pavement repairs to evaluate the equipment, materials and procedures required for in-place asphalt recycling in terms of the efficiency of the components to reduce repair logistics, equipment footprint, and airfield downtime during repairs. The performance of the repairs was evaluated under simulated F-15 aircraft traffic. Data collected from this study were used to develop guidance for the use of in-place asphalt recycling for sustainment repairs on military airfield pavements.
