Abstract
Abstract—Asphalt Concrete-Wearing Course is a layer that is located at the top of flexible pavement structure. Types of damage that often occur in the AC-WC layer are rutting and slippery. AC-WC modification with masterbatch SIR20 is a system that improves AC-WC performance in reducing deformation in pavement structure and improving crack and skid resistance. The method that is used in this study is an experimental method that compares and analyzes the performance of the modified AC-WC layer with variations of masterbatch content are 2%, 4%, 6% and 8% and 0% as a control. The 4% of masterbatch content in the AC-WC modification layer is an effective and efficient option to be applied as a surface layer of a pavement structure.
