Abstract

The opportunity to use crumb rubber for pavement layers is still minimal, while the waste generated is increasing, one way to reduce and utilize the tire material is to add asphalt-concrete mixture - binder course (AC-BC). To increase flexibility, one of them is by using Crumb Rubber from waste tires that pass the No. filter. 4 (4.75 mm) as additive. This study aims to determine the effect of Crumb Rubber as a material and the use of laterite stone as a substitute for coarse aggregate on asphalt mixtures based on the properties of the Marshall mixture. In this study, Marshall test specimens were made with variations of laterite stone as a substitute for coarse aggregate at a level of 50% and the addition of Crumb Rubber at a level of 1%, 2%, 3% and the planned asphalt content was 4%, 4,5%, 5%, 5.5%, and 6% which will then determine the optimum asphalt content, stability, flow, VIM, VMA, VFA and MQ in the Asphalt Concrete – Binder Course. Based on the research results obtained. The best variation isthe use of Crumb Rubber as an additive to Asphalt Concrete – Binder Course by 1% and the addition of Crumb Rubber and the value of Optimum Asphalt Content is 5.58% with Marshall characteristics including stability values of 1082 kg, flow 2.91%, VIM 4.83%, VMA 14.82%, VFA 65.80% and MQ 438 kg/mm. The results showed that the mixture of AC-BC with a substitute for coarse aggregate using 50% laterite stone and Crumb Rubber the requirements for the Asphalt Concrete - Binder Course.
