Abstract

Salah satu cara untuk mengatasi permasalahan lingkungan akibat limbah plastik adalah memanfaatkan limbah plastik sebagai campuran aspal. Limbah plastik telah digunakan untuk peningkatan daya tahan dan ketangguhan aspal. Pada penelitian ini dilakukan analisis karakteristik campuran aspal dengan limbah plastik menggunakan metode numerik dan darinya bisa didapatkan komposisi campuran yang optimum. Karakteristik mekanik yang dianalisa adalah stabilitas, deformasi vertikal (flow), dan Marshall Quotient (MQ). Hasil penelitian menunjukkan bahwa semakin tinggi kadar plastik yang ditambahkan, nilai stabilitas, flow, dan MQ meningkat, tetapi mengakibatkan menurunnya rongga udara dalam campuran aspal. Peningkatan kadar plastik juga berpengaruh pada peningkatan temperatur lembek dari campuran aspal sehingga tingkat kekuatan dan kekerasan aspal juga meningkat. Kadar plastik optimum dalam campuran aspal sebesar 5,361% memberikan stabilitas, flow, dan MQ masing-masing sebesar 2340,65kg, 5,603mm, dan 546,481kg/mm. Ketiga nilai tersebut memenuhi standar Bina Marga 2018. =========================================================== One way to overcome environmental problems due to plastic waste is to use plastic waste as a mixture of asphalt used to increase its durability and toughness. The analysis of the characteristics of asphalt mixtures with plastic waste was conducted using numerical methods and from it the optimum mixture composition can be obtained. The mechanical characteristics taken into account are stability, vertical deformation (flow), and Marshall Quotient (MQ). Based on the results of the study, the higher the amount of plastic added, the value of stability, flow, and MQ increased, but air void in the asphalt mixture decreased. It affected the increasing of the softening temperature maintaining the level of strength and hardness of asphalt. Optimum plastic content of 5.36% affects the optimal stability, flow, and MQ, each of which is of 2340.65 kg, 5.60 mm, and 546.48 kg / mm. All three values have met 2018 Bina Marga standards.
