Experimental study on stability of (ac-bc) made with asbuton modification (retona)

Abstract

Using of asbuton modification asphalt is another alternative to increase mixing quality. Usually, asphalt the aim of asbuton modification to decrease asphalt penetration. For that, it is needed to see the benefit of using asbuton modification as the natural asphalt. In this research mix using 5 asphalt content variation that was 4.5%, 5%, 5.5%, 6%, 6.5%. 15 specimens made using asphalt penetration 60/80 with each asphalt content three specimen. Using asbuton modification (Retona) asphalt mix which was Marshall characteristic to determine the optimum asphalt content, VMA, VFA, VIM, stability, flow and Marshall Quotient. The experiment for optimum asphalt content result of asbuton modification (Retona) asphalts it was 5.5% the test result value in accordance with specifications of the effective asphalt content determination by the Department of Public Works 2006. According to optimum asphalt content for asbuton modification (Retona) asphalt obtained stability 2251.01kg, for the result above it can be stated that asbuton modification asphalt retona mix it can use to develop the quality of pavement course and increasing the stability of the asphalt that used in road pavement.
