Analisa Sifat Stabilitas dan Durabilitas Aspal Beton – Lapis Aus Permukaan (Ac-Wc) dengan Material Pengisi yang Berbeda (Penelitian)

Abstract

Directorate General of Highways issued specifications in planning surface wear layer Asphalt-Concrete Wearing Course (AC-WC). This layer is the wear layer 2 of the layer of asphalt concrete type which is the topmost layer in flexible pavement. In a mixture of AC-WC which typically use stone dust filler in this paper compared using portland cement filler. Cement used was portland cement type I, which is commonly used as a mixture in concrete construction and are often found on the market. Before testing the stability and durability of the mixture, first performed testing on the nature of portland cement and stone dust. After testing both the nature of the filler material, the testing done to get OAC (optimun asphalt content). OAC obtained will have fulfilled the requirements, while Marshall properties VIM and VFA as limiting. The whole nature of Marshall on testing performed already meet the required specifications well in 2x75 and 2x400 blows. Testing at optimum bitumen content with both kinds of blows are a long relationship with the immersion Marshall parameter which is the time period 24, 48, 72 and 96 hours. The highest value of the three comparative stability was found in 100% of cement filler content with value stability 1914,92. While the percentage of the highest durability is also found in 100% filler cement with 96,96 durability value.
