Abstract

Pavement recycling technology, as an alternative technology in road pavement construction and maintenance, is continuously developed. The aim of this study is to modify recycled material by adding a polymer that is able to improvethe physical properties and performance of asphalt and recyled mixture. Asphalt mixture used in this study was Aspahlat Concrete-Wearing Course (AC-WC) containing Reclaimed Asphalt Pavement (RAP), fresh materials, asphalt Pen 60/70, and SBS polymer. The proportion of RAP used was 20% and 30% of the total weight of the mixture. For each RAP variation, asphalt Pen 60/70 was mixed with 0%, 2.5%, and 5% of SBS polymer. Fatigue performance of mixture was, then, measured using 4-Point Bending Test Apparatus. The results show that RAP asphalt has lower penetration and higher viscosity values. Fatigue test shows that the increase in the proportion of RAP will improve the fatigue resistance of the mixture.Keyword: Reclaimed Asphalt Pavement, SBS Polymer, fatigue performance.

Abstract

Abstract Pavement Flexural Stiffness Modulus and Phase Angle tend to bend due to over load of vehicle. Using Reclaimed Asphalt Pavement (RAP), in this case asphalt recycling will decrease deformation endurance of asphaltic mixture. The lower deformation endurance of asphaltic mixture, the worse asphaltic mixture quality is. Therefore modified of asphalt recycling, must be done to improve deformation endurance of asphalt. This research using Styrene-Butadiene-Styrene (SBS) which is elastomer polimer as asphalt modifier. Variation of SBS polimer are 2.5% and 5% of asphalt weight and variation of RAP are 20% and 30% of mixture weight. The value of Flexural Stiffness Modulus and Phase Angle was determined by Fatique testing using Four Point Loading Apparatus. According to the result, the highest Flexural Stiffness Modulus is 5,763.67 MPa which found in variation RAP 30% and SBS 5%. This mixture composition also have the lowest Phase Angle that is 23.33°. The result showing that the stiffness will be increase by adding Reclaimed Asphalt Pavement (RAP) and SBS Polimer. Keywords: Flexural Stiffness Modulus, Phase Angle, Reclaimed Asphalt Pevement (RAP), SBS polimer  Abstrak Nilai Modulus Kekakuan Lentur dan Sudut Fase campuran beraspal memperlihatkan kecenderungan material untuk mengalami deformasi akibat beban yang diterimanya. Penggunaan perkerasan daur ulang, dalam hal ini aspal daur ulang, akan menurunkan tingkat ketahanan campuran beraspal terhadap deformasi akibat beban yang diterimanya. Makin rendah tingkat ketahanan campuran terhadap deformasi yang terjadi, makin buruk mutu campuran tersebut. Untuk itu diperlukan modifikasi terhadap aspal daur ulang sehingga dapat memperbaiki tingkat ketahanannya terhadap deformasi yang terjadi. Pada penelitian ini digunakan modifikasi aspal dengan tambahan polimer elastomer, yaitu polimer Styrene-Butadiene-Styrene dengan persentase 2,5% dan 5% terhadap berat aspal. Kandungan material daur ulang yang digunakan adalah sebesar 20% dan 30% terhadap berat campuran. Nilai-nilai Kekakuan Lentur dan Sudut Fase diperoleh dari pengujian kelelahan campuran menggunakan Four Point Loading Apparatus. Hasil yang diperoleh menunjukkan bahwa nilai Modulus Kekakuan Lentur tertinggi diberikan oleh campuran dengan kandungan material daur ulang 30% dan Styrene-Butadiene-Styrene 5%, yaitu sebesar 5.763,67 MPa. Komposisi campuran ini juga memberikan nilai Sudut Fase yang terkecil, yaitu 23,33°. Hasil analisis menunjukkan bahwa penambahan polimer SBS pada material daur ulang meningkatkan kekakuan. Kata-kata kunci: Modulus Kekakuan Lentur, Sudut Fase, material daur ulang, polimer SBS
