摘要：AbstractIn Portugal, a low temperature technique for pavement recycling has recently emerged. It consists of the warm mix recycled asphalt (WMRA) with bitumen emulsion. It is considered a very interesting solution in terms of technical, economic and environmental performance. Stiffness and fatigue resistance was evaluated by four point bending test was carried on. Permanent deformation was determined by wheel tracking test. Different asphalt recycled mixtures having different bitumen emulsion content were tested. An economic study for application of such mixtures was also made. It demonstrates the advantages of using WMRA with bitumen emulsion in relation to traditional hot mixes.
