Abstract
Asphalt is a binding material in road pavements that is highly sensitive to temperature changes. Modifying asphalt with Ethylene Vinyl Acetate (EVA) effectively increases its resistance to temperature. EVA, a copolymer of ethylene and vinyl acetate, provides strength and flexibility to asphalt. This study examines the effect of EVA plastic asphalt on temperature sensitivity and chemical elements through Fourier Transform Infra-Red (FT-IR) testing. The hot-cold mixing method was used with EVA levels of 0%, 3%, 5%, 7%, and 9%. Results show that adding EVA decreases penetration value, increases viscosity and softening point, and reduces asphalt density. Infrared spectra reveal that 60/70 penetration asphalt and EVA-modified asphalt have similar absorption patterns at specific wavelengths, indicating moderate absorption for C-H stretching in alkanes and C-H bending in methyl alkane groups. EVA addition reduces asphalt's temperature sensitivity, improves penetration index, and enhances thermal stability, making asphalt stiffer and more resistant to temperature changes without significantly altering its basic characteristics. However, its rigidity makes it more susceptible to cracking when overloaded. Despite this, asphalt remains stable at extreme temperatures and does not undergo much change in physical properties.

| Additional Information: | Aspal adalah bahan pengikat dalam perkerasan jalan yang sangat peka terhadap perubahan suhu. Untuk meningkatkan ketahanan aspal terhadap suhu, modifikasi dengan Ethylene Vinyl Acetate (EVA) menjadi solusi efektif. EVA adalah kopolimer dari etilena dan asetat vinil yang memberikan kekuatan dan fleksibilitas pada aspal. Penelitian ini bertujuan untuk mengetahui pengaruh aspal plastik EVA terhadap kepekaan suhu dan unsur kimiawi melalui pengujian Fourier Transform Infra-Red (FT-IR). Metode pencampuran panas-dingin digunakan dengan variasi kadar EVA 0%, 3%, 5%, 7%, dan 9%. Hasil penelitian menunjukkan bahwa penambahan EVA dapat menurunkan nilai penetrasi, meningkatkan viskositas, meningkatkan titik lembek, dan menurunkan berat jenis aspal. Spektrum inframerah juga menunjukkan bahwa aspal penetrasi 60/70 dan aspal plastik EVA memiliki pola absorpsi serupa pada bilangan gelombang tertentu, menunjukkan absorpsi sedang untuk peregangan C-H pada alkana dan pembengkokan C-H pada gugus metil alkana. Penambahan EVA mengurangi sensitivitas aspal terhadap suhu, meningkatkan indeks penetrasi, dan stabilitas termal, hal ini mengindikasi aspal lebih kaku dan tahan terhadap perubahan suhu tanpa mengubah karakteristik dasarnya secara signifikan. Namun, kekakuannya membuat lebih rentan terhadap retak bila mendapatkan beban berlebih. Meskipun demikian, aspal tetap stabil pada suhu ekstrem dan tidak banyak mengalami perubahan sifat fisik. | |||||||||
