Sustainable construction is expected to create a quality environment so that environmental sustainability is maintained. The use of coal as fuel for PLTU have a negative impact on the environment, because it produces waste in the form of fly ash and bottom ash. Lokan freshwater is widely used as a food ingredient. This research study a mixture of AC-WC asphalt using coal fly ash and lokan shell ash as a filler. Research is needed to determine the durability and performance of the pavement that uses these waste materials by using asphalt pen 60/70 as a binder. This study uses Marshall Method and using three variations in the percentage of coal fly ash and lokan shell ash to the total filler. The highest stability obtained at V1 with a value of 1,389.158 kg. Marshall test conducted on the AC-WC blend on OAC for the mixture variation of V1, V2, V3, disclosed that Stability, flow, MQ, VMA and VFB values were acquiescent to the required specification. For the value of VIM on V1 and V3 were not acquiescent to the required spesification. The coal fly ash and lokan shells as filler recommended for alternative material on a mixture of AC-WC.

Porous asphalt is asphalt mixture using open gradation dominated by coarse aggregate to produce a large enough cavity. Bottom ash waste produced by a boiler used in the extraction process of palm oil into crude palm oil. Shells and pulps that has been burned at high temperature between 500°C to 700°C will later become of boiler bottom ash. The aim of this study was to inspect the performance of Porous Asphalt Mixture characteristics which combining bottom ash boiler and cement as filler using Retona Blend 55 as a binder. The specimen preparation were designed by the Australian Asphalt Pavement Association (AAPA) method by parameter of Cantabro Loss (CL), Asphalt Flow Down (AFD), Voids In Mix (VIM), Stability and Marshall Quotient (MQ). The Optimum Asphalt Contain (OAC) obtain was used to prepare specimens within OAC with variation 50 % bottom ash boiler and 50 % cement as filler. The result of study showed that the OAC obtained 6%. Almost all parameter values were meet to the required specification of AAPA (2004). The value of CL is 9.25 %, AFD value is 0.19%, Stability 573.27 kg, flow 4.7 mm and VIM 12.29%. The value of VIM not meet to required specification (18%-25%).

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.

Asphalt is one of the non-renewable natural resources. It is necessary to conduct various studies regarding alternative materials can be used as a substitute for asphalt. Crude palm oil (CPO) has almost the same texture and properties as asphalt, when it is heated it will melt so it can be substituted as a binding agent in the AC-WC layer. Based on the background, this study aims to analyze the effect of 50% CPO substitution and 50% pen 60/70 on the AC-WC layer. This research is based on the Public Works Department General specifications in 2010 using the marshall method by varying 50% CPO and 50% pen 60/70. Variation of 50% CPO and 50% 60/70 pen get Asphalt Optimum Content (AOC) value of 4.5% from the test results of 15 test specimens and 6 specimens using AOC. The results of the test with a 30-minute immersion (stability) all the characteristics meet the marshall parameters that are implied, namely: a stability value of 842 kg, a Flow of 3.1 mm, a VIM of 4.64%, a VMA of 15.30%, a VFB of 69, 67% and the MQ value of 271.51 kg / mm. Marshall testing with a 24-hour immersion (durability) did not meet the specifications required so that this pavement is not durable.
