Abstract

Plastic waste has become an urgent global issue. The volume of plastic waste increases every year, making Indonesia one of the world’s largest contributors to plastic waste. On the other hand, Indonesia faces challenges with highway pavement that is affected by weather conditions such as rainfall, as well as vehicle loads. This study aims to analyze the effect of asphalt content on porous asphalt mixtures. The method used in this study was trial and error, beginning with testing of materials including aggregates, PG 70 asphalt, and fillers, all in accordance with the 2018 Revision 2 specifications of the Ministry of Public Works and Public Housing. The study continued with an evaluation of the Marshall stability, Cantabro loss, and asphalt flow-down parameters with asphalt content variations of 4%, 4.5%, 5%, 5.5%, and 6%. The results showed that all percentages met the requirements (>500 kg), with the 6% asphalt content exhibiting the highest Marshall stability value. The Cantabro loss results met the requirements (<35%) at asphalt contents of 4.5%–6%. Meanwhile, the AFD met the requirements (<0.3%) at all percentages; however, as the asphalt content increased, the AFD value also increased.

Abstract

Porous asphalt emerges as an innovation in flexible pavement that allows water to flow vertically and horizontally into the base layer, while also providing skid resistance, reducing the risk of aquaplaning, and minimizing traffic noise. This study uses 60/70 penetration asphalt as a binder and investigates the addition of mill scale steel waste as a filler in porous asphalt mixtures. Mill scale is a by-product of the steel industry in the form of metal oxide, formed through the hot-rolled process at temperatures of 700–900 °C. The utilization of this waste as a filler is considered strategically valuable as it can reduce environmental pollution while supporting the principles of sustainable development. The purpose of this study is to analyze the characteristics of porous asphalt mixtures with the addition of mill scale filler from steel waste, in order to determine the mixture's performance and its potential application in road infrastructure in Indonesia.
