Laboratory Evaluation of Workability and Moisture ...

Abstract. Warm mix asphalt (WMA) and recycled asphalt pavements (RAP) are two popularly used sustainable technologies in pavement industry. Because RAP materials contain aged binder, its use is limited to a certain percentage in hot mix asphalt (HMA) as it may affect the workability and, fatigue and thermal cracking performance.
