Abstract

Aggregates have an important role in asphalt-concrete mixtures,namely as a contributor to considerable structural strength in the mixture, reducing pavement shrinkage and affecting pavement quality.
The purpose of this study was to determine the quality of Britas River Stone as Coarse Aggregate against the Marshall test value whichwas focused on the stability and flow values in the AC-WC asphalt mixture (Asphalt Concrete – Wearing Course) in road pavement construction. Variations made in this study are variations of 100%, 75%,50% and 25%.
From the analysis of the design asphalt content, the optimum asphalt content value is 6% and in variations of 100%, 75%, 50%, and 25% the stability value meets the minimum standard of Bina Marga, which is 800 kg but has decreased when compared to standard specimensand for melting variations of 100%, 75%, 50%, and 25% the melting value also meets the minimum standard of Highways, which is at least 2 mm-4 mm and compared to standard specimens, it has increased. Based on the results of the Marshal test and the results of calculations on the correlation method, the Stability values of all variants of Kali Brittany 100%, 75%, 50%, 25%, decreased. At the value of the melt (flow) all variants of Kali Britas 100%, 75%, 50%, 25% experienced an increase.
