Volumetric Characteristics of HRS-WC Mixed Using Petroleum Bitumen Grade 60/70 as Binder

Abstract

This study aims to determine the volumetric values consisting of VIM, VMA and VFB on the binder layer mixture using HRS-WC gradation using petroleum bitumen as a binder. The method used in this research is experimental method in laboratory. In this study, variations of asphalt content used were 5.5%, 6.0%, 6.5%, 7.0% dan 7.5%. These variations were obtained from the calculation of effective asphalt level of 5.9%. The results show that the VIM values decreases along with the increase of bitumen content used. VIM values obtained were 6.69%, 5.82%, 5.18%, 4.42% and 3.34%, respectively. The VMA values obtained were 18.12%, 18.38%, 18.84%, 19.21% and 19.30% for each bitumen content. Besides that, the value of VFB is also taken into account and the values obtained for each quality of bitumen content are 63.10%, 68.41%, 72.57%, 76.99% and 82.71%.
