Abstract


ABSTRAK
Volume lalu lintas yang tinggi seringkali mempercepat kerusakan jalan, yang mengakibatkan masalah struktural seperti retak, alur, gelombang permukaan, dan jenis kerusakan lainnya. Salah satu pendekatan yang umum diterapkan untuk meningkatkan kualitas aspal adalah dengan menambahkan material adaptif seperti plastik. Penelitian ini menggunakan metode eksperimental, dengan kinerja dievaluasi melalui parameter uji Marshall yang meliputi stabilitas, aliran, VIM, VFA, VMA, dan Marshall Quotient (MQ). Hasil uji limbah plastik (kresek) yang ditambahkan ke dalam lapisan aspal beton (AC-WC) menunjukkan berat jenis 0,915 g/cm³ dan titik leleh 110 °C. Untuk lapisan aspal beton tanpa aditif, kadar aspal optimum (KAO) ditemukan sebesar 5,49%, dengan stabilitas 1.194,89 kg, flow 3,63 mm, VIM 4,45%, VFA 83,71%, VMA 17,36%, dan nilai MQ 329,17 kg/mm. Sementara itu, campuran dengan limbah plastik menunjukkan kadar plastik optimum sebesar 2,48%, menghasilkan stabilitas 1.287,41 kg, flow 2,78 mm, VIM 4,12%, VFA 73,34%, VMA 16,93%, dan MQ 463,10 kg/mm.

 

ABSTRACT
High traffic volumes often accelerate the deterioration of road conditions, leading to structural issues such as cracks, rutting, surface waves, and other types of damage. One approach commonly applied to enhance asphalt quality is by incorporating adaptive materials like plastic. This study employed an experimental method, with performance evaluated through Marshall test parameters including stability, flow, VIM, VFA, VMA, and Marshall Quotient (MQ). The test results of plastic waste (kresek) incorporated into asphalt concrete wearing course (AC-WC) indicated a specific gravity of 0.915 g/cm³ and a melting point of 110 °C. For the asphalt concrete wearing course without additives, the optimum asphalt content (OAC) was found to be 5.49%, with stability of 1,194.89 kg, flow of 3.63 mm, VIM of 4.45%, VFA of 83.71%, VMA of 17.36%, and an MQ value of 329.17 kg/mm. Meanwhile, the mixture with plastic waste showed an optimum plastic content of 2.48%, producing a stability of 1,287.41 kg, flow of 2.78 mm, VIM of 4.12%, VFA of 73.34%, VMA of 16.93%, and an MQ of 463.10 kg/mm.
