Plastic Waste (PW) is one of the primary sources of pollution, leading to drainage system blockages, thereby causing floods and road pavement damage. One of the major ways to reduce pollution due to plastic waste and excessive exploitation of natural resources is through the development of HDPE. It is also important to reduce damage to road pavement structures by improving the quality of the asphalt used during construction. Therefore, this research aims to analyze the effects of using HDPE shale, an ecologically friendly material, and the addition of Wetfix-Be to asphalt pavements in tropical climates. The study results showed that 5.75% of the OAC asphalt using plastic waste raises the stability value and meets the specification requirements. Specimens of AC-WC concrete asphalt mixture were also tested by immersing them in fresh and seawater for 0.5, 24, 72, and 96 hours. In conclusion, using HDPE plastic waste and Wetfix-Be keeps the AC-WC concrete asphalt mixture stable. Doi: 10.28991/CEJ-2022-08-08-010 Full Text: PDF

ABSTRACT: Road infrastructure is crucial in supporting economic growth and community mobility. Good road conditions are essential for comfort, safety, and transportation efficiency. However, road damage is a common problem, including on Jalan P. Aji Iskandar, Juata Laut, Tarakan, and North Kalimantan. This research aims to develop a WebGIS application to visualize road surface roughness, hoping to improve infrastructure management and decision effectiveness. Road damage in Tarakan is exacerbated by the increase in heavy truck traffic related to the construction of PT Phoenix Resources International’s pulp mill, as identified in the Environmental Impact Analysis (EIA). Therefore, monitoring road conditions is essential. This study measures the International Roughness Index (IRI) as an indicator of road roughness, and IRI data is processed and integrated into WebGIS. The developed WebGIS application presents spatial visualization of road roughness through colour representation to facilitate the identification of improvement areas, detailed information on IRI values per segment, and query and data analysis features. The utilization of WebGIS offers the advantages of accessibility, interactivity, and the ability to display complex spatial data intuitively. The study results show the effectiveness of WebGIS applications in mapping and visualizing the roughness of the road surface. This information can be used by relevant parties, such as local governments and public works offices, to plan road maintenance efficiently and data-driven. It is hoped that this can improve the quality of road infrastructure in Tarakan, reduce the negative impact of industrial development, and improve the safety and comfort of road users. The development of this application also opens up opportunities for further research related to integrating other data, such as traffic data and visual road damage.

Corrosion in bridge girder beams frequently leads to significant structural damage, such as concrete spalling and reduced reinforcement, which directly impacts the bending capacity. This study experimentally assessed the efficacy of a combined repair strategy of grouting and Glass Fiber Reinforced Polymer (GFRP) reinforcement on simulated damaged reinforced concrete beams. Twelve beams were tested with various repair configurations, including a standalone grouting repair and a combination of grouting with GFRP in strip and U-wrap configurations. The primary objective was to comprehensively evaluate the enhanced flexural capacity and failure modes of these repaired beams. The results indicated that GFRP reinforcement, particularly the U-wrap configuration, significantly improved the beams' flexural capacity. Beams with the GFRP U-wrap configuration achieved an average maximum load of 32.50 kN, surpassing the control beam's 29.74 kN by 9.27%. Conversely, a standalone grouting repair drastically decreased the load capacity to 14.49 kN, highlighting its inefficiency in strength restoration. Debonding failure at the grout-concrete interface was identified as the primary cause of this reduction. The U-wrap configuration outperformed the strip configuration, likely due to its enhanced shear resistance and confinement. The GFRP strain analysis showed linear behavior at low loads but significant deviations at higher loads, which indicates debonding. All beams exhibited a dominant flexural cracking failure mode, with the addition of GFRP reducing the number of cracks. In conclusion, the combined grouting and GFRP reinforcement, especially the U-wrap configuration, proved to be an effective strategy for repairing damaged RC beams. However, achieving strong adhesion between the repair materials and the concrete is crucial to prevent debonding and optimize structural performance. Further research on enhancing adhesion and optimizing GFRP configurations is recommended.
