Development of A Base Course Material Produced from Second Time Pavement Recycling Materials Modified with Asphalt Emulsion

Abstract

This paper presents the development of pavement materials through the process of recycling old pavement materials for reuse. The material developed in this research is the first grade with cement for the second improvement with asphalt emulsion and cement. from the test results of unconfined compressive strength, flexural strength and water absorption of this developed sample material compared with the control material with the same cement content. It was found that mixing asphalt emulsion with cement was able to improve the mechanical properties and anti-water absorption properties compared to cement-only blends. The test results show the potential for further application of the old roadway material recycling process through the second quality improvement with asphalt emulsion combined with cement. The improved material can be used as a prototype material for further application in road repair and construction in Thailand.
