Karakteristik Campuran AC-WC Menggunakan Aspal Emulsi pada Berbagai Variasi Substitusi Filler Abu Ampas Tebu Sesuai dengan Tata Cara PT Izza Sarana Karsa (Characteristics of AC-WC Mixtures Using Asphalt Emulsions in a Wide Variety of Substitution of Bagasse Ash Filler According to the PT Izza Sarana Karsa)

Abstract

The diversification of pavement construction materials and the road pavement materials technology is one of steps being pursued by our government. Asphalt emulsion is asphalt which mixes with water in the form of emulsion. The merger of asphalt and water is possible since there is a catalyst additive. In this study, the presence of stone dust as a filler would be replaced by bagasse ash as an alternative. This study aimed to find out the advisability of the bagasse ash in replacing the filler in the mixture of Asphalt Concrete Layer AC-WC with Asphalt Emulsion and seek the influence of the addition of bagasse ash over the characteristic of Marshall, Indirect Tensile Strength, and Permeability. The study was conducted in five stages. The first stage was the testing of material characteristics consisting of agregrate, asphalt, and bagasse ash tests. The second stage was determining the optimum bitumen content on the proportion of alternative filler 0%, 25%, 50%, 75% and 100% bagasse ash. The third stage consisted of the Marshall and Indirect Tensile Strength tests. The fourth one was to conduct Permeability test. The fifth stage consistedof the analysis, discussion, and conclusion of the testing results. The result showed that Clereng bagasse ash as an alternative filler in the mixture of grade asphalt concrete layer AC-WC with asphalt emulsion met the specified requirements so that it could be used as an alternative filler. The mixture of grade asphalt concrete layer AC-WC with asphalt emulsion using bagasse ash as the alternative filler had a change in Marshall characteristic at KAO stability was decreased, the flow increased. MQ value increased, Density value increased, VITM value decreased, VFWA value increased, and VMA value decreased. As the proportion of the bagasse ash filler was increasing, the Indirect Tensile Strength of the mixture of grade asphalt concrete layer AC-WC with asphalt emulsion was increasing. On the permeability test, it showed that the mixture had a poor drainage characteristic towards water after being varieted by the proportion of bagasse ash filler. The permeability value of the mixture of grade asphalt concrete layer AC-WC with asphalt emulsion using bagasse ash as the filler caused a decrease.
