Cold Asphalt Mixtures Characteristics with Cement and Sugar Industry Waste Material as Mineral Filler

Abstract

Cold mix asphalt is bituminous material that produced at ambient temperatures. Many advantages can be obtained from cold mix asphalt especially, economic and environmental aspects this come from no need to heat of aggregate and bitumen for purpose the production and laying mix which are remain necessary demand to hot mix asphalt production. However, cold mix asphalt show inferior performance at early life and high porosity. This lab investigation focuses on improving the Cold Bitumen Emulsion Mixtures (CBEMs) containing 2% ordinary Portland cement (OPC) by adding Sugar industry Waste (SW) with different percentages i.e. 2, 4, 6 by total mass of aggregate. The optimum SW content was selected based on Indirect Tensile Strength (ITS) test which was 4%. ITS for the modified mix increased significantly to more than 55% and 32% in comparison with the untreated mixtures and CAEM with 2% OPC, respectively. On the other hand, the results of tests for Marshall Stability (MS), Marshall flow (MF) and index of retained strength (IRS) tests were encouraged. The value of MS and MF for mixtures with 4% SW increased about 140% and 38% respectively while, IRS improved about 45% in comparison with untreated mix. Finally, this research has gave highly improved cold bituminous emulsion mixtures (CBEMs) with SW in addition to environmental and economic benefits.
