Abstract

Asphalt mixture for highway pavement consists of aggregate, filler, and asphalt. Materials commonly used as fillers are cement, sand, lime, and rock ash. These materials have limited availability, are relatively expensive, and are nonrenewable materials. One of the alternatives to the filler is oil palm bunch ash which is a waste of the palm oil processing industry and is a renewable natural resource. The purpose of this study was to determine the effect of peat water on the characteristic value of the Marshall AC-WC mixture with oil palm bunch ash as filler. This study used the asphalt content used in the determination of KAO of 5.5%, 6%, 6.5%, 7%, and 7.5%. While the variations filler used were 0%, 2%, 4%, 6%, and 8%. This research was conducted under the General Specifications of Bina Marga 2018. The results of this study show that the AC-WC layer mixture when immersed in peat water has an increased KAO value in the range of 6.08% 7.30%, for variations of filler 6% and 8%. not obtained because the characteristic parameters Marshall do not meet the specifications and the value of stability and durability has decreased. The filler 4%with immersion time of 0.5 hours gave the highest stability value of 919.93 kg, while the lowest yield was obtained at filler 0% with 24 hours soaking time of 513.80 kg. For Variations of filler 0%, 2%, and 4% with soaking time of up to 3 hours, the IKS value is more than 90% so that it meets the specifications. Keywords: Palm Bunch Ash, Filler, Peat Water, AC-WC

Abstract

Fly ash and bottom ash (FABA) is one of the residues produced from the coal burning process which is included in hazardous and toxic waste. However, the content of FABA is one reason for the utilization of the waste has been used. The purpose of this study was to determine the utilization of fly ash and bottom ash in the subbase on the carrying capacity of the road and with the appropriate proportions to optimize profit utilization. This research is based on laboratory testing by testing the CBR of immersion by the 2018 Bina Marga standard. The subbase layer mixture was made in four variations. Variation I was without fly ash and bottom ash. In variations II and III fly ash and bottom ash were used as substitutes, and in variation IV fly ash and bottom ash were used as additives. Variation I with 0% fly ash and bottom ash content resulted in a CBR value of 64%. Variation II and variation III with 22% and 25% fly ash and bottom ash content resulted in CBR values of 93% and 84%. Variation IV with 25% fly ash and bottom ash content results in a CBR value of 73% so that all CBR values are fulfilled on the 2018 Bina Marga standard and fly ash and bottom ash are suitable for use in the mixture of road pavement layers.

Abstract

The filler in a concrete asphalt mixture that is commonly used is Portland cement which is relatively expensive. It is expected that the filler is replaced with cheaper materials. Flying ash is a relatively cheaper material because fly ash is waste material. The purpose of this study was to determine the effect of the use of fly ash fillers in ACWC asphalt mixtures. This study used the percentage of optimum asphalt content (KAO), namely 5%, 5.5%, 6%, 6.5% and 7%. The proportion of fly ash used is 0%, 2%, 4%, 6% and 8%. The specifications used follow the 2018 Bina Marga Standard using the Marshall method. The results of this study indicate that the AC-WC mixture using fly ash filler has a better stability value than not using fly ash filler. The recommended level of fly ash for AC-WC mixtures according to specifications is 6% because it has better values of KAO 6,58% stability, flow, VIM, VMA, VFA, and MQ and meets the 2018 Bina Marga standards. Keywords : Fly ash, Filler, AC-WC, Bina Marga Specification 2018

Abstract

In Indonesia, flexible pavements quite often occured prematurely. A good quality of pavement needs materials that fulfill a specification, and sometime also requires additional modifier. Rubber can be used to modify and increase of asphalt concretes quality. The addition of rubber is able to improve shear resistance at high temperatures, prevent cracks, bleeding, stripping, and permanent deformation of asphalt concretes. This study try to investigate the effect of natural rubber latex addition on a binder course typed asphalt concrete (AC-BC) based on volumetric properties of Bina Marga Specification Revision 3. The latex contents used as bitumen substitution were 0%, 4%, 6% and 8% of bitumen content. The results showed that the addition of rubber latexdecreased the optimum asphalt content and increased mixture densities. A maximum of 6% latex content could be used as bitumen substitution, where its Marshall characteristics still met the specification.Keyword : Rubber Latex, Laston AC-BC, Marshall characteristics, Specification ofBina Marga 2010 Revision 3.

Abstract

Asphalt concrete wearing course (AC-WC) is the top layer in flexible pavement. Asphalt concrete is a mixture of asphalt, coarse aggregate, fine aggregate and filler. Many types of filler have been used to improve asphalt concrete performance. In this research, a combined of brick ash and rice husk ash was used as filler. As wasted products, this mixed filler can be used as an alternative replacement of Portland cement due to their similar chemical compounds. The objective of this research is to analyze Marshall characteristics (stability, flow, volumetric properties and Marshall Quotient) of an ACWC mixture containing a combination of Portland cement and a mixed of 40% brick ash and 60% rice husk ash as filler. Ratios of cement and the mixed ash used were 100:0, 50:50, and 0:100. After obtaining the optimum asphalt content for each different filler variation, Marshall test were performed to obtain flow, stability and density values. The result of tests showed that the composition of filler 50:50 gives Marshall characteristics with stability value of 1250,5 kg and air void of 4,846%. The composition of filler 0:100 gives Marshall characteristics with the highest stability value of 1692,9 kg and the smallest air void of 4,533%, which satisfied the specifications of Bina Marga 2010 Revision 3. Keywords: rice husk ash, brick ash, AC-WC, filler
