Abstract

Hot Rolled Sheet (HRS) is one type of hot asphalt mixture consisting of a mixture of fine aggregate, coarse aggregate, filler, and asphalt. The results of the kandora mountain stone aggregate wear test are 26.78%, the combined specific gravity is 2.59. The design of the HRS-WC mixture uses graphical and analytical methods to obtain the aggregate composition of the HRS-WC asphalt mixture that meets the specifications, so that the optimum plan asphalt content (Pb) is 6.5%. 7%, 7.5%, 8%, 8.5% with KAO value of 7%. The number of test specimens was 30 samples using asphalt penetration 60-70. The results of conventional marshall testing research with Pb 7.5% are density 2.30, VIM 3.29%, VMA 17.53%, FVB 81.22%, stability 880.96 kg, flow 2.93, and marshall Quotient 302.60. Testing fine aggregate variation with KAO using 20% sand mixture obtained density 2.27, VIM 4.85%, VMA 18.41%, FVB 73.66%, stability 653.88kg, flow 3. 37, and marshall quotient 195.69, 50% sand mixture obtained density results 2.27, VIM 4.85%, VMA 18.41%, FVB 73.66%, stability 653.88kg, flow 3.37, and marshall quotient 195.69 The remaining marshall strength index test was obtained at 91.01%.  Based on the results of aggregate characteristics testing and Marshall testing, the Kandora Kandora Mountain stone meets the 2018 Bina Marga specifications for HRS-WCHot Rolled Sheet (HRS) mixtures are one type of hot asphalt mixture consisting of a mixture of fine aggregate, coarse aggregate, filler, and asphalt.

Abstract

Asphalt Concrete – Wearing Course is a layer designed to withstand traffic loads and protect the underlying layers from damage caused by environmental factors such as water and temperature. This research aims to analyze the effect of partial replacement of eggshell ash filler on the properties of AC-WC mixtures with soaking variations. This study used 0%, 20%, 40%, 60%, 80%, and 100% eggshell ash. The sample preparation consisted of no soaking, 3 days of soaking, and  9 days of soaking (the sample is soaked for 24 hours then removed and allowed to stand at room temperature for 24 hours; this is repeated 3 times and 9 times). The tested things were stability, flow, VMA, VFB, VIM, content weight, and 200-pass ratio. The sample testing used the Marshall tool. The test results showed that the best variation was 60% eggshell: 40% cement with 3 days of soaking.

Abstract

The design of asphalt mixtures in Indonesia generally employs the conventional Marshall method, with a compaction of 2x75 blows for heavy traffic and an air void limit of 3%-5%. To assess field compaction, a Core Drill Test is performed using a heavy Tandem Roller, with 18 passes conducted in this study. The research aims to compare the density of the AC-WC surface layer used in the laboratory and in the field, as well as to analyze the thickness and density test results of the AC-WC surface layer according to specifications. The test results showed a slight difference between field density (2.25 g/cc) and laboratory density (2.27 g/cc), with a difference of 0.02 g/cc, which is considered nearly equivalent. However, this density variation should be noted as it can affect the load-bearing capacity and durability of the pavement layer. From STA 2+800 to 3+000, all samples' thickness and density met the specifications. Although this difference does not align with the asphalt mixture design (JMF), it falls within the tolerances specified in the 2018 Revision 2 Bina Marga standards, indicating that the differences in thickness and density are still acceptable.

Abstract

Damage to highways in Indonesia is often caused by the inadequate quality of asphalt compaction, which does not conform to the optimum temperature during on-site construction. Asphalt compaction is highly dependent on temperature to ensure the mix achieves maximum density, which strengthens the durability and service life of the road. This study explores the use of Maiting River stones from North Toraja Regency as materials in asphalt concrete binder course (AC-BC) mixtures, aiming to determine the characteristics and feasibility of the material.The research methods include material sampling, aggregate characteristic testing, mix design planning, specimen preparation, conventional Marshall testing, determining the optimum asphalt content (OAC), compaction temperature variations, and Marshall Immersion testing.The results show that the aggregate characteristics of Maiting River stones from North Toraja Regency indicate that the AC-BC mixture with 60/70 penetration asphalt comprises 58.75% coarse aggregate, 36.99% fine aggregate, and 4.27% filler, resulting in a design asphalt content of 5%. In this study, the optimum asphalt content used was 5.50%, with compaction temperature variations of 150°C, 180°C, and 200°C. The test results show that the optimum compaction temperature for the asphalt mixture (AC-BC) is 150°C, achieving Stability of 1575.89%, Flow of 3.15%, FMA of 15.08%, VIM of 3.12%, VFB of 79.29%, and MQ of 499.94%. These values meet the standards specified in the 2018 Bina Marga specifications.

Abstract

Pavement is an important element in road construction consisting of a layer of aggregate and binder, which serves to support traffic loads and protect the soil layer from climate change and great pressure. Based on the type of binder, pavements are divided into flexible, rigid and composite pavements. This research provides an overview of the planning and quality testing of flexible pavement, and aims to analyze the volume requirements and thickness of flexible pavement in road projects using secondary data from PT Mareraya Multipratama Jaya and Bina Marga 2018 (Revision 2) specifications. The main focus is on flexible pavement that uses asphalt as the main binder, with a 6 cm thick LASTON AC-BC layer and 4 cm thick LASTON AC-WC. The method used is observation through secondary data collection, including analysis of pavement thickness as well as the volume of the mixture of aggregates, asphalt, and fillers. The analysis showed that the total volume of AC-BC and AC-WC mixes were 3302.35 tons and 2104.09 tons, respectively, with bitumen volume of 183.28 tons for AC-BC and 127.93 tons for AC-WC. There was a significant difference in core drill thickness between the self-inspection and inspectorate inspection, the inspectorate inspection showed lower density. Factors such as traffic load, asphalt aging, and environmental conditions may influence the difference in results.
