Feasibility of Utilization of ECC Mix in Pavement Construction

Abstract

Engineered cementitious composites are a class of high-performance fiber-reinforced cementitious composites with strain hardening and multiple cracking properties. The specialty of engineered cementitious composite is its tensile strain carrying capacity to be 300–500 times that of conventional concrete. Analysis results suggest that engineered cementitious composite can greatly extend the service life of the structure due to its high fatigue and ductility performance. This has led to the wide acceptability of engineered cementitious composite and has the potential to be used as an overlay, interlayer, and even as a surface course in pavement construction. The present paper discusses the advantages and disadvantages of engineered cementitious composite in comparison to conventional concrete in terms of strength and durability characteristics, life cycle costs, and field applications. It has summarized the performance of engineered cementitious composite in different courses of the pavement. In this study, an empirical relation has been derived for a relation between flexural strength and compressive strength of the engineered cementitious composite.
