Curing of Cold in Place Recycled Asphalt Mixtures: Toward a Standard Test Method

With escalating oil prices, pavement recycling is an attractive choice for road maintenance since it allows considerable savings as compared to new construction. It also mitigates environmental impacts, reduces the use of virgin materials, and minimizes transportation of materials off-site. Recycling of asphalt pavement is based on two different techniques: Hot In-place Recycling (HIR) and Cold In-place Recycling (CIR). Although CIR has significant advantages, the main disadvantage concerns the assessment of the CIR before being overlaid. Traditionally, assessment of the CIR mixes has been done on the basis of moisture content and compaction measurements - both of which require destructive and time-consuming testing. There is a need to develop a reliable test method that rapidly and accurately identifies when the CIR is ready for overlay. To date, a feasibility study has indicated that simple, non-destructive tests can monitor the changes in the moisture content of the mixes and that these measurements can be interpreted to give information about the curing of CIR. A more comprehensive experimental program will be carried out to calibrate the developed test method. This paper presents an overview of the problem, summarizes the major findings of the feasibility study, and describes the proposed methodology.
