In this study, the use of fly ash material as substitution material of fine fraction on asphalt mixture of AC-WC Concrete to study Marshall and Durability. Concrete of bitumen is one of plywood type of pavement construction of pavement. In this study will focus on the extent of the effect of Ash ash Effect on Asphalt Concrete Mixture -WC tehadap Stability and density of the concrete mixture of asphalt. and in the end it is hoped that later fly ash of coal which used to be a waste material can be utilized as substitution material of fine fraction and alternative filler in road construction. The conclusion obtained from the analysis of the influence of fineness to the stability and density of AC-Wc asphalt concrete is as follows : Stability: Value stability of the mixture in the review of fineness variation tends to increase substitution of fly ash content variation occurs at the rate of 6% optimum zone 3 is equal to 1.435kg and at the level of 8% zone 3 decreased to 1.421kg.KepadatanNilai Density (Bulk density Standard) the mixture in review of the fineness variations tends to increase. variation of fly ash content substitution occurred optimum at 8% level of zone 3 that is equal to 2,421kg / cc. Some suggestions that can be submitted to improve the results performance of concrete asphalt mixture (AC-WC) using subtitution smoothness and fly ash content are: a) for subsequent research in order to analyze the optimum asphalt content to the optimum ash content as the greater the use of fly ash content, the Marshall parameter value tends to be less than optimal andb) It is advisable to combine other types of substitution materials with fly ash to obtain more economical results.

The road is an infrastructure that plays an essential role in the development of a region which is a connection between one region and another. The concrete asphalt layer (laston) is the most commonly used road violence in the Indonesian region consisting of asphalt, aggregate and filler. In an effort to add substitutes of fine material that can be used as a material in asphalt mixture, then easy-toobtained rice husk ash are used in research as an alternative to fine material in asphalt mixture. The asphalt used in this research is the rubber asphalt sir 20 (Standard Indonesian Rubber) which is derived from PT. MBS (Modifikasi Bitumen Sumatera). This research was conducted with the aim of knowing the optimum value of the mixture rice husk ash as a fine material replacement against AC-BCNR coated laston and to find out how much the effect of the smoothness of rice husk ash as a fine material replacement against AC-BCNR coated laston is reviewed from stability and density. The percentage of rice husk ash used in this research is 4 %, 6 % and 8 % for zone 0, Zone 1, Zone 2 as well as zone 3 as substitution of fine materials in a mix of AC-BCNR and normal test objects without rice husk ash. The research used marshall testing methods by reviewing the effects of rice husk ash on the value of stability and density. Based on the results of testing the marshall parameter, reviewed by the variety of zones and the percentage of the level of substitution of rice husk ash it can be concluded that the optimum value of the use of the rate of rice husk ash exists in the zone 2 percentage 4 %. Marshall standard optimum stability value is located in zone 2 percentage 4 % by 1301 kg while in zone 2 percentage 6 % there is a drop back to 1285.6 kg. Optimum density value (bulk density) lies in zone 2 percentage 4 % of 2,297 gr/cc whereas in zone 2 percentage 6 % there is a drop back to 2,291 gr/cc.Keyword: Rice husk ash, Rubber asphalt, AC-BCNR, Stability, Density

Asphalt concrete is a flexible pavement structure mixed with asphalt concrete which is composed of fine aggregate, coarse aggregate and filler material, with asphalt also as a binder. Rice husk ash is the result of burning rice husk waste. Rubber asphalt is a natural polyterpene synthesized through the enzymatic polymerization of isopentyl pyrophosphate. SIR 20 solid natural rubber is made from coagol (used latex) with an impurity content of 0.2 or processed products such as lamps, sitangin. The aim and objective of this research is to determine the effect of fly ash (rice husk ash) on the stability and density of AC-WCNR and to determine the optimum mixture value of AC-WCNR. The research method is a quantitative method that collects data from the results of experimental research in the form of numbers and can be calculated and is in numerical form. The fineness of rice husk ash to AC-WCNR asphalt increases the stability and density of the mixture up to zone 2 with a percentage of rice husk ash of 4%. The standard Marshall stability value increased in zone 2 with a rice husk ash percentage of 4%, amounting to 1294.9 Kg. The density value increased by 2.287 gr/cc in zone 2 with a percentage of 4%. The optimum value for using rice husk ash content is in zone 2 with a percentage of 4%.Keywords: Asphalt Concrete, Rubber Asphalt, Rice Husk Ash, Stability, Density

This research aims to investigate the impact of variations in coarse aggregate mixtures on concrete compressive strength and to compare the effects of using split and coral aggregates on the resulting concrete compressive strength. The experiments were conducted at the laboratory of Bina Darma University, Palembang, South Sumatra, using 54 test specimens in the form of 10 x 20 cm cylinders, divided into 27 test specimens for each split and coral aggregate mixture. The research results indicate that a 10% split aggregate mixture has a significant effect on concrete compressive strength, while a 30% coral aggregate mixture also has a substantial impact on concrete compressive strength, with an inverse relationship to the split aggregate mixture. Furthermore, this study achieved optimal concrete compressive strength test results at 28 days of age, with a 10% split aggregate mixture reaching a compressive strength of 61.34 MPa and a 30% coral aggregate mixture reaching a compressive strength of 47.88 MPa.Keywords: Concrete, Variation of Mixture, Compressive Strenght

Roads are the most important infrastructure in the land transportation system in Indonesia. Guaranteeing a good pavement structure will ensure the continuity of a good transportation system as well. In Indonesia, there is a lot of waste from factories that has not been utilized optimally. The large amount of waste will cause problems in its disposal because apart from the large costs that must be incurred in building disposal facilities, this waste can also pollute the environment. Coal ash becomes waste, so using it as a filler in the AC-WC mixture is one solution to reduce the amount of coal waste itself. In this research, coal waste in the form of bottom ash will be used which will be used as a filler for the stability and density of asphalt concrete (AC-WC). The objectives of this research are as follows: To determine the effect of the bottom ash mixture as a filler on the characteristics of the resulting asphalt concrete marshall. And knowing how much optimization the use of Coal Waste has on the stability of the AC-WC Asphalt Concrete mixture. Based on the results and discussion in the previous chapter, it can be concluded that the effect of bottom ash coal ash substitution on the stability and density values of AC-WC asphalt concrete can be concluded as follows:Based on the results of testing the marshal parameters in terms of the substitution of bottom ash coal ash, it can be concluded that the influence of the stability value on the optimum bottom ash coal ash is at a percentage of 4% in zone 0 with a value of 1,499kg and meets the 2018 Bina Marga specifications Revision 2. Then , the influence of the optimum density value (Bulk Density Standard) is located in zone 2 at a percentage of 4% with a value of 2,352kg. and Based on the results of Marshall parameter testing in terms of variations in bottom ash coal ash substitution, it can be concluded that the use of a mixture of bottom ash coal ash content for asphalt stability and density (AC-WC) lies in a mixture of 4%.
