Introduction to a Sustainable Pavement Construction using Foamed Cold Mix Asphalt Technology

Abstract

This paper introduces a sustainable pavement construction using foamed cold mix asphalt (FCMA) technology in order to achieve a better understanding of its road material properties. It is important because the use of cold mix asphalt lags behind hot mix asphalt applications. The methodology used in this paper is by characterisation into FCMA technology based on literature review and experimental studies. The experimental study covers a laboratory investigation of FCMA properties. The closure can be drawn in four issues, i.e. foamed bitumen characteristics, the use of foamed bitumen in road construction, the role of mixing in the process of generating foamed asphalt material, and the considerations for selecting foamed bitumen properties in order to achieve an optimised FCMA
