Abstract

Lombok Island is one of the earthquake-prone areas, located between two earthquake generators. Based on these conditions, it is expected that construction in earthquake-prone areas can meet the standards. Shear walls are one of the earthquake-resistant structural systems used to resist lateral forces. Three alternative shear wall shapes will be analyzed using the numerical method: the L, I, and T shapes. The types of loads to be analyzed are dead loads, live loads, and earthquakes. Drawing from the findings of the conducted analysis, it is discovered that the most effective shear wall position in resisting lateral forces is the shear wall located at the corner of the building, based on the values of the drift that occur in the x and y directions. In addition, increasing the number of shear walls can reduce the internal forces that structural components experience. The optimum drift value is obtained from alternative 1, the L-shaped shear wall (elbow), with a drift value of 0.000495 mm in the x direction and 0.000883 in the y direction.

Abstract

The increasing volume of multilayer plastic waste, which is difficult to recycle, has encouraged the exploration of alternative applications in road construction materials. This study aimed to analyze the effect of multilayer plastic waste content on the Marshall characteristics of Asphalt Concrete–Binder Course (AC-BC) mixtures and to determine the optimum plastic content that provides the best mixture performance. An experimental laboratory method was employed using the Marshall test on AC-BC mixtures with an optimum asphalt content (OAC) of 5,15% and multilayer plastic waste contents of 3%, 4%, 5%, 6%, and 7% by asphalt weight. The evaluated parameters included stability, flow, Void in Mix (VIM), Void in Mineral Aggregate (VMA), Void Filled with Bitumen (VFB), and Marshall Quotient (MQ). The results indicated that all multilayer plastic variations produced stability values ranging from 1076 to 1262 kg, flow values from 3.10 to 3.53 mm, and Marshall Quotient values from 309 to 386 kg/mm, all of which satisfied the 2018 Bina Marga General Specifications. The VMA values ranged from 16.57% to 17.57%, while VFB values ranged from 67.43% to 72.39%. The VIM values ranged from 4.57% to 5.72%, with the 5%, 6%, and 7% mixtures slightly exceeding the maximum specification limit. The 4% multilayer plastic content exhibited the best performance, producing the highest stability value of 1262 kg while satisfying all Marshall parameters. These findings demonstrate that multilayer plastic waste has strong potential as an alternative additive in AC-BC mixtures to improve pavement performance while supporting sustainable plastic waste management.
