Abstract

HRS is a mixture consisting of hard asphalt and coarse, fine aggregate, and filler. One of the wastes that have not been used optimally is glass powder. When viewed physically, glass powder has small particles and, material weight is large enough to complete the requirements as a filler for asphalt mixtures. This study aims to determine the effect of glass powder on marshall characteristics, namely density, stability, VMA, VIM, VFB, flow, and MQ. This research method includes the preparation of materials and tools followed by testing of coarse aggregate, fine aggregate, and filler. After asphalt mix design for marshall testing to obtain the Optimum Asphalt Content (KAO) that will be used for the test object is 9 pieces with a ratio of 25%, 50%, and 75% glass powder filler from a total weight of 3% as a partial replacement of cement in the HRS-WC mixture. The results showed that the flow value of 3.7 mm had completed the requirements for using 50% glass powder filler. The use of 75% glass powder filler produces an MQ value of 369,124 Kg/mm. Whereas VIM and VFB values in the use of a combination of 25%, 50%, 75% glass powder filler don’t comply with the requirements specifications of Bina Marga 2018 revision 2. In general, the glass powder cann’t use as an alternative to cement filler

Abstract

High water content, water saturation, and low carrying capacity are characteristics of clay soils. The road body may have an uneven surface. On the other hand, in the dry season it will harden and have a high  carrying capacity so that a lot of dust is scattered on the road and blocks the driver's view. As a result, the neighborhood can experience traffic jams and accidents. Check the CBR and PI values to see if there is an increase in clay after stabilization using a mixture of Palm Oil Fuel Ash and cement with variations (0%  POFA + 2% Cement), (3% POFA + 2% Cement), (5% POFA + 2% Cement), and (7% POFA + 2% Cement). Test method Sieve Analysis, Atterberg Limit, Specific Gravity, Moisture Content, Compaction and CBR. Cement and palm oil bunch ash produced a CBR value of 7.4% compared to a natural soil CBR value of 1.59%. The CBR value of the soil will increase, the dry unit weight value will decrease, and the plasticity  value will decrease with the higher proportion of Oil Palm Bunch Ash and cement

Abstract

The issue concerning the retaining wall revolves around the potential risk of landslides triggered by soil displacement, primarily observed in the main drainage channel within Mendawai's trading district. Despite the installation of retaining walls along the channel, persistent issues have led to structural failure or even collapse. In response to this challenge, researchers aim to investigate the impact of retaining wall usage on slope stability in the construction project of drainage channels in Mendawai, Palangka Raya, Central Kalimantan. This study will utilize manual calculation methods alongside analysis using geotechnical software, specifically Plaxis 8.6. Analysis of manual calculations reveals a significant discrepancy in safety factors. Manual calculations yield a slope stability value of 1.463 and a shear stability value of 0.834, both falling below the safety standard of 1.5. Meanwhile, Plaxis 8.6 analysis indicates a retaining wall bearing capacity value of 1.599, also below the safety standard set at 3. This indicates that the retaining wall experiences failure and fails to meet the anticipated safety standards.

Abstract

Clay soil has high plasticity and low shear strength characteristics, making it a challenge in construction projects, especially in areas with high water content, such as Bereng Bengkel District, Palangkaraya City. To address this issue, polymers and biopolymers have been used as stabilization materials to enhance the shear strength of the soil. This study aims to evaluate the effect of adding polymers and biopolymers on the mechanical parameters of clay soil, particularly cohesion (CC) and internal friction angle (ϕ). Laboratory experiments were conducted following SNI 2825:2015 standards for direct shear testing. Clay soil samples were collected from Bereng Bengkel and mixed with polymer (polyacrylamide) and biopolymer (xanthan gum) at concentrations of 0.5%, 1.0%, 1.5%, and 2.0%. Shear strength parameters were analyzed to determine the effectiveness of each stabilization material, with the optimal concentration determined based on maximum cohesion and internal friction angle values. The results showed that the addition of polymer could increase cohesion by up to 70% and the internal friction angle by up to 130% at concentrations of 1.0% to 1.5%, while biopolymers could increase cohesion by up to 39% and the internal friction angle by up to 313% at concentrations of 1.0% to 2%, compared to the initial values. These findings indicate that soil stabilization with polymers and biopolymers significantly improves the shear strength of Bereng Bengkel soil. The study concludes that the optimal combination of stabilization materials can significantly enhance the mechanical properties of clay soil and opens opportunities for further research with other additive materials such as lime or cement.
