The Effects of Using Nano-Silica in Cold-In Place Asphalt with Emulsified Bitumen

Abstract

Because hot mix asphalt (HMA) is both costly and harmful to the environment, the use of cold in-place recycled (CIR) asphalt is important to highway pavement. But, because CIR pavement properties are not as effective as HMA, addition of additive materials to the mixture is required to improve the pavement characteristics. Effects of using nano-materials on the mechanical properties of CIR asphalt are assessed in this chapter. The results show that the use of nano-materials improves the mechanical properties of CIR.
