Abstract
Permasalahan kelembapan (moisture) dapat menimbulkan kerusakan dan penurunan kualitas pada struktur perkerasan jalan lentur seperti munculnya raveling dan stripping. Untuk mengatasi permasalahan akibat kelembapan aspal modifikasi polimer digunakan sebagai teknologi yang memberikan tingkat adhesi yang lebih baik pada agregat dan aspal (Debatosh Roy, 2013). Tujuan dari penelitian ini adalah untuk mengetahui kadar polimer optimum terhadap tingkat adhesi pada campuran aspal panas. Penelitian dilakukan dengan penambahan polimer Superplast dari Iterchemica dengan kadar polimer 0%, 4%, 5%, dan 6%, dan dengan kadar aspal 6,1%. Metode yang digunakan dalam mengevaluasi tingkat adhesi adalah Boiling Water Test yang ditentukan dalam standar ASTM D3625, dan menggunakan image processing software yaitu Image J untuk pengolahan datanya. Untuk mengidentifikasi pengelupasan yang terjadi digunakan fitur threshold dimana pada gambar 8-bit grayscale dapat memberikan 256 tingkat pencahayaan (threshold) mulai dari 0 (hitam sempurna) hingga 255 (putih sempurna). Hasil penelitian menunjukkan bahwa penambahan polimer pada campuran aspal mampu meningkatkan adhesi campuran aspal panas dengan melihat parameter berupa coating ratio. Nilai threshold 20, 25, 30, dan 35 digunakan untuk merepresentasikan pengelupasan yang terjadi. Campuran aspal panas dengan kadar polimer 5% merupakan kadar polimer optimum karena menunjukan peningkatan nilai coating ratio rata-rata tertinggi dibandingkan dengan benda uji tanpa polimer yaitu sebesar 3,258% pada rentang threshold 20-255, sebesar 3,682% pada rentang threshold 25-255, sebesar 4,037% pada rentang threshold 30-255 dan sebesar 4,283% pada rentang threshold 35-255./Moisture susceptibility can cause damage and decrease the quality of the flexible pavement structure such as raveling and stripping. To overcome the problems caused by moisture, polymer modified asphalt is used as a technology that provides a better level of adhesion to aggregates and asphalt (Debatosh Roy, 2013). The purpose of this study is to determine the optimum polymer content on the level of adhesion to hot mix asphalt. The research was conducted with the addition of Superplast polymer from Iterchemica with a polymer content of 0%, 4%, 5%, and 6%, and with an asphalt content of 6.1%. The method used in evaluating the level of adhesion is the Boiling Water Test specified in the ASTM D3625 standard, and using image processing software, namely Image J for data processing. To identify the stripping that occurs, the threshold feature is used, which in 8-bit grayscale images can provide 256 levels of illumination (threshold) ranging from 0 (perfect black) to 255 (perfect white). The results showed that the addition of polymer to the asphalt mixture was able to increase the adhesion of hot mix asphalt by looking at the parameters in the form of coating ratio. Threshold values of 20, 25, 30, and 35 were used to represent the stripping that occurred. Hot asphalt mixture with a polymer content of 5% is the optimum polymer content because it shows the highest average increase in coating ratio value compared to the specimen without polymer, which is 3.258% in the 20-255 threshold range, 3.682% in the 25-255 threshold range, of 4.037% in the 30-255 threshold range and 4.283% in the 35-255 threshold range.
