Material Characterization of Cold-mix Recycled Asphalt Pavement

摘要

Reuse or recycling of existing pavement materials is a new rehabilitation technology used by transportation agencies. The increasing interest in and use of recycled pavement materials has created a need for information related to the engineering properties of such materials. First this paper reviews the necessary, feasibility and mechanistic analysis of recycled asphalt mixture, then summarizes the findings of a laboratory study to characterize and design recycled asphalt concrete mixtures using different tests. The laboratory tests carried out on the material were conventional test methods including unconfined compressive strength, cleavage strength, resilient modulus and shrinkage properties tests. The results of the laboratory can be taken as reference in design, engineering and further research.
