Abstract

This study evaluates the performance of Asphalt Concrete-Wearing Course (AC-WC) mixtures incorporating shell waste and waste glass as additives for sustainable pavement applications. The optimum asphalt content was determined at 5.8% using the Marshall method, producing balanced volumetric and mechanical properties that satisfy heavy traffic specifications. Waste glass addition without shell waste increased mixture stiffness but did not consistently achieve optimal stability due to volumetric imbalance. A synergistic effect was observed when shell waste and waste glass were combined. The mixture containing 5% shell waste and 5% waste glass demonstrated the most favorable performance, characterized by higher stability, proportional Marshall Quotient, controlled air void distribution, and improved structural integrity. Increasing shell waste content to 7.5% and 10% did not enhance performance and tended to reduce volumetric balance. Economic evaluation indicates a material cost reduction of approximately 1.72% per kilometer compared to conventional mixtures, without compromising mechanical performance. The findings confirm that the optimal incorporation of shell waste and waste glass is technically feasible and economically beneficial for sustainable AC-WC pavement construction.

Abstract

This laboratory-based quantitative experimental study evaluated the performance of Asphalt Concrete Wearing Course (AC-WC) modified with wood ash as filler and Expanded Polystyrene (EPS) styrofoam as asphalt additive. The research verified the base binder through penetration testing, yielding an average penetration value of 69.4, confirming the use of 60/70 penetration grade asphalt. Asphalt content was validated using extraction testing, resulting in an average binder content of 5.80%, ensuring consistency between design and actual mixture composition. Marshall testing was conducted to assess mechanical and volumetric characteristics, including stability, flow, Marshall Quotient (MQ), VMA, VIM, and VFB. The results demonstrated that EPS dosage significantly influenced volumetric balance and load resistance within the mixture. Among the evaluated combinations using 4% wood ash and EPS levels of 0%, 0.5%, 1%, and 1.5%, the optimum performance was achieved at 1.5% EPS, which satisfied key Bina Marga 2018 Revision 2 requirements for VIM, VMA, VFB, stability, and flow. However, MQ values remained below specification for all mixtures, indicating limitations in stiffness–deformation ratio and the need for further optimization and durability testing.

Abstract

Asphalt Concrete Wearing Course (AC-WC) road pavement functions as a crucial wearing layer to maintain its performance and service life, but conventional asphalt still faces problems with its high cost and dependence on non-renewable natural resources. Therefore, this study analyzes the use of palm kernel shell waste and dammar resin as a modified AC-WC mixture, looking at its Marshall characteristics and suitability to Bina Marga specifications. The method used is an experimental laboratory with variations of palm kernel shells of 0%, 2.5%, 5%, 7.5% plus dammar resin of 0%, 2%, 4%, and 6%. Marshall tests check stability, flow, VIM, VMA, VFA, and MQ according to SNI and Bina Marga. The results show that the addition of both has a positive effect, with the optimum at 7.5% palm kernel shells and 6% dammar resin increasing stability and meeting technical standards, making it highly potential as an environmentally friendly and cost-effective alternative

Abstract

The growth of urban activities in Semarang City has led to an increase in traffic movement, particularly along Jalan Majapahit, which serves as a primary corridor connecting the city center with residential and industrial areas. Road rehabilitation works on this segment caused lane narrowing, resulting in reduced road capacity and affecting overall traffic performance. This study aims to analyze traffic characteristics and road performance on Jalan Majapahit before and during the road rehabilitation period. The evaluated parameters include traffic volume, side friction, road capacity, degree of saturation (DS), and level of service (LOS), based on the Indonesian Road Capacity Guidelines (PKJI 2023). The research method involved field surveys consisting of vehicle volume counts, side friction observations, and geometric road measurements. The collected data were then analyzed to determine road capacity and degree of saturation under both conditions. The results indicate that before rehabilitation, the degree of saturation reached approximately 0.736, representing relatively stable traffic conditions. However, during the rehabilitation period, the DS increased to 1.192, indicating that traffic demand exceeded road capacity, leading to congestion, reduced vehicle speeds, and traffic queues. Consequently, the level of service deteriorated from category C before rehabilitation to category E during rehabilitation
