Abstract

Sama Guna Village is a division village located in Tanjung District, North Lombok Regency. By the formation of a new government institution, it is certainly not immediately supported by adequate facilities and infrastructure. One of them is the Village Office. In this case, Sama Guna Village wants to make a design related to the needs of the Village Office. However, this has become a quite tough activity for the Village based on: budget constraints, optimizing the utilization of Village funds and Village apparatus human resources. As a developer in the field of Civil Engineering and active in the field of development, as well as a form of scientific service to the community, assistance is needed to assisting activities for the engineered of the Village Office Detail Engineer Design (DED). Starting from activities: measurement; brainstorming with village and community officials; deliberations and assistance in the manufacture of DED, a design was found that is effective, strong and economical. The resulting building area is 313.96 m2.

Abstract

In Indonesia, many infrastructure development projects are underway, particularly in the transportation sector, including roads and bridges. Road construction typically uses a variety of materials, with asphalt functioning as the binder, while pavement layers often rely on non-renewable resources. This study investigated the effect of incorporating lightweight brick as filler on the properties of AC-WC mixtures. Test specimens were prepared using an Optimum Asphalt Content (OAC) of 6% and varying proportions of cement (S) and lightweight brick (BR) as fillers: 1% S: 0% BR, 0.25% S: 0.75% BR, 0.50% S: 0.50% BR, 0.75% S: 0.25% BR, and 0% S: 1% BR. The Marshall test was conducted to evaluate key parameters, including flow, stability, Marshall Quotient (MQ), Voids in Mix (VIM), Voids Filled with Asphalt (VFA), and Voids in Mineral Aggregate (VMA). The results indicated that the highest stability was achieved in the first variation (1% S: 0% BR) at 1,315 kg, whereas the lowest stability occurred in the fifth variation (0% S: 1% BR) at 1,191 kg. Flow values for all mixtures met specification requirements, ranging from 2 mm to 4 mm. VIM values were within the standard range of 3%–5%. The highest VMA was observed in the fifth variation (18.73%), while the lowest was in the first variation (17.83%). All mixtures also met the minimum VFA specification of 65%. These findings demonstrate that lightweight brick waste can be used as a filler in AC-WC mixtures without compromising the mixture’s quality, making it a viable and sustainable alternative in asphalt concrete production.
