UTILIZATION OF RECYCLED ASPHALT TO MAKE NEW AC-BC LASTON BASED ON 2018 AND 2019 BUILDING SPECIFICATIONS

Metode daur ulang menggunakan RAP merupakan salah satu cara dalam kegiatan rehabilitasi. Keutungan pemanfaatan RAP yaitu mengurangi penumpukan material dan mengurangi penggunaan sumber daya alam. Pada penelitian ini yang ditinjau yaitu pengaruh pemanfaatan RAP (Reclaimed Asphalt Pavement) sebagai penambahan campuran agregat pada pembuatan laston AC-BC dengan menggunakan filler abu batu sebagai bahan campuran, terhadap karakteristik marshall berdasarkan Spesifikasi Umum Bina Marga Devisi 6 Tahun 2018 dan Spesifikasi Khusus Interim Bina Marga Tahun 2019. Metode penelitian yang digunakan adalah analisis deskriptif kuantitatif. Persentase variasi kadar aspal yang digunakan dalam pembuatan benda uji yaitu sebesar 2.5%, 3%, 3.5%, 4%, 4.5%, 5%, 5.5%, 6%, 6.5% dari total berat campuran. Dari hasil uji marshall menunjukan bahwa nilai kadar aspal optimum yang dihasilkan dari penggunaan RAP 25% pada campuran variasi C komposisi 2, berada kadar aspal 6.00% yang memberikan nilai stabilitas 1721.7 Kg, nilai Flow 3.87 mm, nilai VIM 4.44%, nilai VMA 18.31%, nilai VFA 75.76% dan MQ 446.0 kg/mm, nilai tersebut dianggap lebih baik karena memberikan suatu campuran yang sangat elastis namun tetap stabil sehingga campuran ini masih diatas batas minimal Spesifikasi Bina Marga 2018 maupun Spesifikasi Bina Marga 2019.
 

The method of recycling using RAP is one of the ways in rehabilitation activities. The advantage of RAP utilization is to reduce the accumulation of material and reduce the use of natural resources. In this study, the effect of the use of RAP (Reclaimed Asphalt Pavement) as the addition of aggregate mixtures in the manufacture of AC-BC laston by using rock ash filler as a mixture, to the characteristics of Marshall based on General Specifications of the Bina Marga Division 6 2018 and Special Specifications for Interim Community Development Marga 2019. The research method used is quantitative descriptive analysis. Percentage variation of asphalt content used in the manufacture of test specimens is 2.5%, 3%, 3.5%, 4%, 4.5%, 5%, 5.5%, 6%, 6.5% of the total weight of the mixture. The results of the Marshall test show that the optimum asphalt content resulting from the use of RAP 25% in a mixture of variation C composition 2, are 6.00% asphalt content which gives a stability value of 1721.7 Kg, Flow value of 3.87 mm, VIM value of 4.44%, VMA value of 18.31% , VFA value of 75.76% and MQ 446.0 kg / mm, the value is considered to be better because it provides a mixture that is very elastic but remains stable so that this mixture is still above the minimum limit of 2018 Bina Marga Specifications and 2019 Bina Marga Specifications.
