Abstract

Good highway construction depends on one factor, namely aggregate quality. Cubic, flaky and elongated aggregates are usually obtained from crushing large stones with a stone crusher. Cubic aggregates are the best form for their use because they have many sides to bind each other. This study aims to see the effect of using flat aggregates on flexible pavements of highways. This study uses a mixture of Hot Rolled Sheet Wearing Course (HRS-WC). This study compares standard mixtures that meet specifications (coarse aggregates using 10% flat aggregates) with several combinations of flat aggregate use in coarse aggregates. From the results of this study, the percentage of safe use of flat aggregates is 13.33%, which if the use of flat aggregates exceeds this value, the marshall parameters obtained are no longer in accordance with the specifications of the HRS-WC mixture.

Abstract

The increase in traffic in Indonesia is in the form of increasing volume and weight of vehicles. Good road construction quality is needed, namely high stability. Additives in asphalt mixtures are used to improve the quality of the mixture. One form of additive that can be used is cellulose fiber found in cigarette filters. Cigarette filters produce waste that has an impact on the environment. This study aims to determine the effect of cellulose acetate fiber from cigarette filters and its optimum content in the AC-WC (Asphalt Concrete Wearing Coarse) mixture. The Marshall method was used in this study. Cigarette filter waste of 3%, 5%, 7%, and 9% was added to the asphalt. The results of the study were an optimal percentage of cigarette filter waste of 7%, with a stability value of 2804.14 kg and an MQ value of 477.26 kg / mm. The addition of cigarette filters to asphalt resulted in an increase in the specific gravity value and a decrease in the asphalt penetration value.
