Abstract

The aim of this research is to know characteristic of Marshall Stability and Marshall Immersion value of the old asphalt mixing that recycling by rejuvenating diesel oil. The old Asphalt mix from asphalt pavement deteroration on Jalan Soekarno Hatta, Palu Central Sulawesi.Result of extraction test of old asphalt mix was to found the asphalt content 4,6%. This scenarios of recycling asphalt in this research were five varieties of asphalt content and five varieties of rejuvenating agent. Varieties of asphalt content are 4,6% (without added of new asphalt), 5,1%, 5,6%, 6,1% and 6,6%. Varieties of rejuvenating agent are 0%, 5%, 10%, 15% and 20%. Specimen of asphalt pavement recycled testing by Marshall stability testing machine and volumetric analysis.The result of Marshall testing on Optimum Bitumen Content was found that increasing of rejuvenating agent content in asphalt recycling mix caused Marshall stability ,Marshall Immersion and Density Values were decrease. From Marshall stability value, maximum content of rejuvenating agent still required specification is 35,29% and from Marshall immersion value, maximum content of rejuvenating agent is 46,18%

Abstract

Asphalt Concrete Binder Course (AC-BC) Pavement is a type of asphalt pavement located between base layer and wearing course.  The study was conducted describing the the effect of the use of rice husk ash onthe characteristics of asphalt concrete AC-BC mixtures. The purpose of this study was to determine thecharacteristics of the asphalt concrete binder course mixtures (AC-BC) which uses rice husk ash as filler,determine the optimum percentage of rice husk filler in AC-BC pavement mixtures. Research materials include coarse aggregate, fine aggregate and rice husk ash. Coarse and fine aggregateobtained from Stone Cruiser of Taipa and Palu River, while rice husk ash obtained fromBiromaru area in Sigi Regency. Asphalt used in this study is Asphalt pen. 60/70 produced by Pertamina.Investigation and testing of these materials has been carried out in the Laboratory of Transportation andHighways, Department of Civil Tadulako University of Palu.Research has been carried out by using rice husk ash filler variation of 0%, 25% and 50%. The datacollected includes characteristics of volumetric and Marshall test characteristics of AC-BC pavementmixture on each rice husk ash content. The data include density, VIM, VMA, VFB, Stability, flow, MarshallQuotient value and residual stability of the mixture. The data is processed and displayed in graphical form,  then do a comparative analysis between the characteristics of the AC-BC mixture that uses rice husk ash andwithout rice husk ash.The results of the study found that increasing the percentage of rice husk ash content in the mix AC-BC tendsto increase the use of bitumen content. It can be seen from the increasing value of Optimum Bitumen Content(OBC) on rice husk ash variation of 0% - 50%. The results also gain an increase in the durability of the ACBCmixtureofricehuskashonthevariationof0%- 5%asindicatedbytheincreasedtheresidualstabilityvalueofthe AC-BC pavementmixtures.Maximum stabilityoccursinrice huskashcontentof25%.Keywords: Asphalt Concrete Binder Course (AC-BC), rice husk ash
