Investigating Filler Characteristics in Upgrading Cold Bituminous Emulsion Mixtures

TL;DRAbstract

Abstract Cold Bituminous Emulsion Mixtures (CBEMs) could offer significant advantages in contrast to traditional Hot Mix Asphalt (HMA). These advantages are redaction of energy consumption, reduction of emission of pollutants, and reduction of total costs. To date, researchers have attempted, intensively, to upgrade CBEMs’ engineering characteristics to gain their whole advantages. Adding active filler materials such as Ordinary Portland Cement (OPC) develop these characteristics. In this paper, selected waste or by-product materials are investigated as alternatives to OPC. Although OPC alone or with activator has proven successful in improving curing time and mechanical properties, the successful use of waste or by-product alternatives could represent a unique environmental and economic achievement. Thus, for the first time, waste or by-product materials (PFA, PSA, GGBFS, APC, and BFA) were investigated individually and not as Supplementary Cementitious Material (SCM) for improving th
