Abstract

Roads play a crucial role in local economies, supporting the distribution of goods and the mobility of citizens, but are often damaged by heavy traffic loads, poor drainage and inadequate infrastructure. Asphalt pavement is a popular choice due to its durability and affordable construction costs. Building waste includes construction and demolition waste, containing recyclable to toxic materials. Management of this waste is effective to reduce costs and support industry sustainability, in Indonesia, granite stone waste is widely generated. Analysis of Marshall characteristics in AC-WC mixtures using granite stone powder as a substitute for filler with a variation of 30% resulted in a stability value of 2487 kg, a VMA value of 36.51%, a flow value of 3.35 mm, a VIM value of 26.19% and an MQ value of 742 kg/mm that meets specifications. The VFB test value of 28.27% does not meet the 2018 Bina Marga specifications. While the granite stone powder with a variation of 60% produces a stability value of 2568 kg, a VMA value of 37.31%, a flow value of 3.4 mm, a VIM value of 27.12% and an MQ value of 756 kg/mm that meets the specifications. Meanwhile, the VFB test value of 27.31% does not meet the 2018 Bina Marga specifications. The presentation results of the mix design on cement filler are hot bin I by 17%, hot bin II by 45%, hot bin III by 32%, cement filler 6%, asphalt 6%.

Abstract

Roads as transportation infrastructure play an important role in regional development and are used to transport basic necessities. Certain materials with specific durability are used for road construction, but damage can occur due to natural phenomena, excessive pressure, or material quality. This damage can endanger drivers and often causes accidents. The Bina Marga Road Maintenance Manual lists various types of damage, but this study only focuses on inspections to detect cracks. In Muara Angke, Central Jakarta, one ton of fish bone waste is produced every month from the fish cracker making process. This waste, which produces an unpleasant odor and contains BOD, COD, and TSS, pollutes the environment and makes the 400 m² industrial area unhealthy. Due to lack of skills and technology, local communities have not been able to process or utilize this fish bone waste effectively. The results of Marshall testing on the composition of AC-WC asphalt using fish bone powder waste with variations of fine aggregate substitution of 0%, 25%, and 50%, and asphalt content of 5%, 6%, and 7% did not meet the 2018 Bina Marga specifications for Stability, Void in Air, Marshall Quotient, and Void in Material values. The Marshall characteristics obtained from the mixture with fish bone powder waste are not comparable to the regular AC-WC mixture without waste. In addition, the VIM value for the mixture with 6% asphalt content and waste variations of 0%, 25%, and 50% also did not meet Bina Marga standards. However, all VMA and VFA levels still meet the asphalt and aggregate specification criteria according to Bina Marga 2018.

Abstract

Waste, the residue of production that has lost its primary purpose, including garbage and wastewater, is a global problem due to its potential for contamination and the spread of disease. In Indonesia, it is estimated that around 21.88 million tons of waste will be produced in 2021. To address this problem, it is important to find ways to reduce waste, such as using it in asphalt production. In an effort to create a more durable road pavement, researchers have experimented with mussel waste as an additive to improve asphalt quality. This study examined the use of mussel waste to replace fine aggregate in asphalt concrete layers, in the hope of extending the life of the road. When mussel waste powder was substituted for 25% filler in the Asphalt Concrete-Wearing Concrete mixture, Marshall characteristic analysis resulted in a stability value of 2487 kg, VMA 36.51%, flow 3.35 mm, VIM 26.19%, and MQ 742 kg/mm, all of which met the requirements. However, the VFB value of 28.27% does not meet the requirements of Bina Marga 2018. The combination produces a stability value of 2568 kg, VMA 37.31%, flow 3.4 mm, VIM 27.12%, and MQ 756 kg/mm ​​in the variation of green mussel powder waste 50%, all of which meet the requirements. However, the VFB value of 27.31% does not meet the requirements of Bina Marga 2018. The mixture design with the results of the cement filler presentation shows the following composition: 17% for hot bin I, 45% for hot bin II, 32% for hot bin III, 6% for cement filler, and 6% for asphalt.

Abstract

Laston, commonly known as AC (Asphalt Concrete) in Indonesia, is a type of asphalt concrete with continuous gradation designed to handle large traffic volumes. According to Waani (2013), stability is the main characteristic that makes laston a vital component. This study examines the use of coconut shell charcoal, previously considered waste, as an environmentally friendly additive. Coconut shells and rock ash are used as fillers in asphalt mixtures. It is important to test asphalt containing coconut shell charcoal to evaluate changes in its properties. The performance of asphalt mixtures, including flow, stability, VIM, VMA, Marshall Quotient, VFA, and durability values ​​are expected to increase with the addition of coconut shell charcoal. The results of the Marshall characteristic analysis of the AC-WC mixture with a filler variation of 25% substituted with coconut shell charcoal powder are 2487 kg for stability, 36.51% for VMA, 3.35 mm for flow, 26.19% for VIM, and 742 kg/mm ​​for MQ, all of which have met the specifications. However, the 2018 Bina Marga standard was not met by the VFB value of 28.27%. On the other hand, the variation of 50% coconut shell charcoal powder produced a stability value of 2568 kg, an MQ value of 756 kg/mm, a VMA value of 37.31%, a flow value of 3.4 mm, and a VIM value of 27.12%, all of which were still within the acceptable range. However, the VFB value of 27.31% did not meet the 2018 Bina Marga requirements. The findings of the mixture design presentation for cement filler are as follows: 17% for hot bin I, 45% for hot bin II, 32% for hot bin III, 6% for cement filler, and 6% for asphalt.

Abstract

The number of new road constructions is increasing, with the main focus on the repair of old roads. However, these roads often deteriorate before reaching their intended service life due to excessive vehicle loads, lack of maintenance, and problems with the asphalt mixture. Research on additives to asphalt mixtures, such as red brick waste, is needed to improve the quality and durability of roads. The red brick industry, which is largely traditional, often produces defective products that contribute to the failure rate in brick making. The addition of red brick debris to asphalt is expected to not only improve the quality of the pavement but also offer a low-cost solution to the waste problem. Marshall characteristic analysis on AC-BC mixture using red brick powder as a substitute for fine aggregate with variation 0 or normal produces a stability value of 1202.04 kg, for variation 1 with 20% red brick powder waste replacing sand, produces a stability value of 1074.39 kg, for variation 2 with 40% red brick powder waste replacing sand, produces a stability value of 1021.2 kg, while for variation 3 with 60% red brick powder waste replacing sand, produces a stability value of 914.83 kg. These values ​​meet the 2018 Bina Marga specifications.

Abstract

Concrete is the main material in building construction made from a mixture of gravel, sand, cement, and water. This material is the most commonly used in construction. The development of concrete technology brings various innovations to improve its quality, including the addition of additional materials or substitutes such as bamboo reinforcement. Bamboo reinforcement is an alternative because of its abundant availability, easy to obtain, and economical price, thus offering a more affordable construction solution. Research has explored the use of bamboo as a substitute for steel reinforcement, considering that bamboo has a strong mechanical structure. In Indonesia, Petung, wulung, tali, and Ori bamboo are the most commonly used types. Concrete design standards and compressive strength testing are regulated by SNI, with the quality of concrete tested according to SNI 1974-2011 and the increase in concrete flexural strength measured based on SNI 4431-2011. Bamboo reinforced beams at the age of 7 days reached 25 KN, at the age of 14 days reached 28 KN and at the age of 28 days reached 29 KN. Where it can be concluded that the compressive strength of concrete increases at the age of 7 to 28 days. The bagasse reinforced beam at the age of 7 days reached 20 KN, at the age of 14 days reached 23 KN and at the age of 28 days reached 24 KN. Where it can be concluded that the compressive strength of concrete increased at the age of 7 to 28 days but the results at the age of 28 days did not reach 100%. The iron reinforced beam at the age of 7 days reached 26 KN, at the age of 14 days reached 30 KN and at the age of 28 days reached 33 KN. Where it can be concluded that the compressive strength of concrete increased at the age of 7 to 28 days. Based on the results of the study, it was found that the beam with the addition of bamboo and iron reinforcement experienced an increase in the percentage of flexural strength testing while the beam reinforced with bagasse at the age of 28 days did not reach the desired target.

Abstract

Modern construction technology has developed with the principle of environmental concern, integrating natural materials into construction materials to support environmentally friendly practices. Green construction includes processes that minimize the use of hazardous materials, do not disturb the peace of the population, limit waste production, maintain the balance of nature, and avoid the use of hazardous chemicals. In industry, rapidly developing technology often produces negative waste. Population growth increases the need for construction materials from natural and artificial sources. One solution is the utilization of local resources, including waste and garbage, which not only reduce pollution but also as an alternative to conventional building materials, such as the use of bagasse waste in construction. Based on data analysis and conversations that have been described in the previous chapter regarding the use of bagasse waste with variations of 0%, 10%, and 15%, the results of the flexural test of fc'25 concrete, namely after 28 days, the strength of ordinary concrete is 3.67 MPa, while variation 1 with 10% bagasse reaches 4.06 MPa, while for variation-2 with 15% bagasse reaches 4.49 MPa. The test results appear to meet the minimum requirements of 14% of the planned concrete compression test. The increase with the addition of sugarcane pulp was an average of 10%.

Abstract

Infrastructure development is a top priority in Indonesia due to economic growth and demographic changes. With a budget of 149.81 trillion in 2021, infrastructure development is prioritized for economic recovery from COVID-19. Increased construction activities, including buildings, roads, and bridges, increase the demand for materials such as concrete, which is chosen for its strength and affordable cost. However, excessive sand mining for concrete has a negative impact on the environment. In addition, the increase in construction waste emphasizes the importance of waste management. This study explores the use of lightweight brick waste as a partial substitute for sand in concrete, focusing on its effect on the compressive strength of concrete. The following are the conclusions that can be drawn based on data analysis and discussion regarding the utilization of lightweight brick powder waste with variations of 0%, 12%, and 17% that have been explained in the previous chapter, the results of the compressive strength test on normal concrete at the age of 28 days reached 440 kN (fc'24.91), while variation 1 with 12% lightweight brick substitution reached 345 kN (fc' 19.53), and variation 2 with 17% lightweight brick substitution reached 309 kN (fc'17.49).

Abstract

Flexible pavement is a road construction that uses aggregate and asphalt as a binder to create a strong road layer. This pavement is able to withstand and distribute vehicle loads to the underlying soil layer and is often used on roads with reduced loads and traffic. This study used AC 60/70 penetration asphalt, which is suitable for hot climates and high traffic. With the large amount of red brick waste in Indonesia, this study utilizes the waste as a partial substitute for fine aggregate in the laston mixture. The title of this study is "The Effect of Using Brick Waste on Asphalt Concrete Wearing Course Mixture". The Marshall test characteristics on the AC-WC mixture using red brick powder as a filler substitute with a variation of 40% resulted in a stability value of 2487 kg, a VMA value of 36.51%, a flow value of 3.35 mm, a VIM value of 26.19% and an MQ value of 742 kg/mm ​​already meeting the specifications. For the VFB test value of 28.27%, it does not meet the 2018 Bina Marga specifications. Meanwhile, red brick powder with a variation of 80% produces a stability value of 2568 kg, a VMA value of 37.31%, a flow value of 3.4 mm, a VIM value of 27.12% and an MQ value of 756 kg/mm ​​already meets the specifications.
