Utilization of palm shells fly ash as filler on the mixture of Asphalt Concrete Wearing Course (AC–WC)

Abstract

The scarcity of natural component of road construction, such as river sand, gravel and rock; against high market demand causing the increased of material market prices. Therefore, there is a call for innovations of substitutes to reduce the demand of natural resources use. Aceh Barat is boastful of palm plantation supplying the palm oil industry. Palm oil production generates waste including fly ash. This study aims to investigate the physical properties of fly ash to be used as filler in asphalt concrete mixture AC WC. The study also inspects the Marshall characteristics of the mixture of Asphalt Concrete Wearing Course (AC- WC) used palm shells fly ash. Results of the study displays that there are characteristics value of the AC-WC mixture which is compliant with the Specification for Asphalt Concrete Mix by Department of Public Work 2010. KAO 5.51% for palm shells fly ash filler. The stability value of the AC-WC mixture used palm shells fly ash as filler is 1279.54 kg; flow 3.5 mm; MQ 362.18; Density 2.4 gr/cm3; VIM 4.18%; VMA 15.55% dan VFB 74.21%. This research benefits is sought to realize the cooperation of the agricultural industry in the field of road transportation which is environmentally friendly and sustainable.
