Techniques for the effective use of recycled asphalt pavement material as a civil engineering material

Abstract

From the viewpoint of the effective use of materials and environmental conservation, the recycling of waste materials generated at construction sites has been increasingly required. Asphalt pavement materials that are left after pavement repair are among such waste materials. Thus, for the purpose of effectively using waste asphalt, the applicability of recycled asphalt as a civil engineering material was examined by conducting laboratory tests and the trial construction of embankments. It was found that waste asphalt could be used in embankments and in frost blankets, and could be used for improving unsuitable soil.
