Application Technology of Thin Asphalt Concrete Overlay on Old Pavement

摘要

Application technology of thin asphalt concrete overlay on old pavement is an important measure to keep pavement structural bearing capacity and its service performance. This paper is mainly focus on the characteristics application technology of thin asphalt concrete overlay on old pavement and the flaws of existing studies, discusses the concept of thin asphalt concrete overlay, introduces the design principle and applicable condition of thin asphalt concrete overlay, and researches the structure and thickness design of thin asphalt concrete overlay. This paper also summarizes the design method and construction technique for thin asphalt concrete overlay on old pavement. The results can provide a basis for construction and rational design of thin asphalt concrete overlay on old pavement.
