Functional and field performance of epoxy asphalt technology – state-of-the-art

Abstract

There is an increasing demand for high strength and more durable materials in the asphalt technology market. In response to the demand, epoxy asphalt mixture (EAM) is one relatively new technology for use as a paving material in flexible pavements. There are various research works carried out on the laboratory and field performance of EAM. However, comprehensive research covering functional and field (F&F) performance of EAM is lacking. The main purpose of this review is to bridge this gap via the analysis of the functional properties of EAM. Consequently, the field performance of EAM in different case studies is reviewed and the serviceability of EAM in various transportation infrastructure is investigated. This paper also reviews the life cycle cost and maintenance of EAM. The major findings indicate that EAM shows superior F&F performance compared to the traditional hot and warm asphalt mixture. Additionally, the use of EAM is beneficial in the structure of pavements in tunnels and on bridge decks. In conclusion, the higher F&F performance of EAM supports the development of better performing pavements for various applications.
