Abstract

In general, existing bridges in Indonesia that were built in the 1980s do not take into account the morphological shape of the river flow. This has an impact on the bridge that was built at the river's location to collapse due to damaged pillars. Damage to the pillar was caused by scouring of the river flow that occurred during a certain period and the collapse did not occur suddenly. This research was conducted to determine the potential occurrence of river flow scouring on the existing bridge pillars that occurs within a certain time period. Scour depth analysis was carried out using several empirical methods and using the Hydrologic Engineering Center's River Analysis System (HEC-RAS) program. Case studies were carried out on the Cipamingkis Bridge (after retrofitting) and the Cipunegara Bridge. In the case study, the depth of the scour that occurred in each bridge pillar will be compared for the 100 year return period of flooding. Based on the results of the analysis, the scour depth of the Cipamingkis bridge pillars (after strengthening) for the 100 year return period of flooding is 5 m. While the scour depth for the Cipunegara Bridge for the 100 year return period of flooding is 7 meters. The scour depth of the Cipunegara bridge pillar is greater than that of the Cipamingkis bridge. Mitigation technology to avoid the collapse of the pillars of the Cipunegara and Cipamingkis bridges is to construct a river flow protection structure and construct a pillar protection structure. Making rip-rap around bridge pillars is one type of prevention that is done so that the bridge pillars don't suddenly collapse. Reinforcement of rip-rap on the pillars of the Cipunegara and Cipamingkis bridges can reduce the occurrence of scouring processes by 60% for the 100 year return period of flooding. Keywords: bridge, pier, existing, scourings, Hec-ras, rip-rap

Abstract

Toll road infrastructure has shown a significant number in recent years. This condition should be followed by operational service which meet the user expectations, in fact sometimes it doesn’t. A Minimum Service Standard (MSS) has already been set to ensure that users receive adequate services. However, users' needs and expectations are dynamic making it necessary to gather users' opinion and suggestion based on the available services. The aim of this research is to evaluate the service performance by exploring the opinions and expectations of toll road users regarding the service performance and the aspects of safety, security, and comfort regarding to MSS. This paper performed a survey by using online questionnaires, involving toll road users in Indonesia, on February 2018. The questionnaire results were then analyzed by using descriptive statistics. Results were shown that the users tend to 3 prioritize safety, then followed by security and comfort elements, respectively. The indicator of sufficient street lighting determines the fulfillment of MSS according to the perception of the users (1 from 18 indicators). This indicator has been included in the MSS. All indicators that affect users’ satisfaction have been found in MSS, except the indicator about ‘the availability of contacting the call center for users’ assistance’. Therefore, this paper suggest that the indicator mentioned in prior will be suggested to be in further consideration. Key words: Minimum Service Standard, safety, security, comfort, performance indicator

Abstract

The population of bridges on National Road in 2020 has reached 21,054 units with a total length of 587,309 meters. About 10.5% of bridges have a service life of less than 10 years, 68.1% in the range of 10 - 50 years, and 5.3% more than 50 years. As the service life increases, the condition of the bridge will decrease. This bridge condition is obtained from the results of a detailed inspection using the visual method. The accuracy of this method is highly dependent on the objectivity, ability, and experience of the bridge inspector. The large population of bridges, variations in service life and conditions, and limited experienced inspectors are obstacles in conventional bridge inspections. As an alternative, the dynamic test method can be used to check bridge conditions more quickly and accurately. The natural frequency of the dynamic test can be used to determine the integrity condition and the level of structural damage, by comparing it to the theoretical frequency. So far, the theoretical frequency is determined based on calculations or structural modeling. The limited data of technical specifications, design drawings, and as-built drawings are often an obstacle. Experience and special skills are also needed in calculating or modeling this structure. This study aims to analyze the correlation between frequency and bridge span based on bridge dynamic test data in Indonesia. The results obtained a mathematical formula, where the value of the frequency of the bridge is correlated to the span of the bridge with a correlation coefficient of -0.85. This coefficient shows that the relationship between the variables under consideration is very strong and inverse, where the longer the bridge span, the smaller the vertical frequency value of the bridge.

Abstract

The Piket Nol national route is an alternative route across the southern island of Java that connects the Lumajang Regency with the Malang Regency. Landslide-prone areas are starting from KM Turen 53 to KM Turen 59 on this route. The Simplified Bishop method is used in analyzing slope stability and modeling soil nailing reinforcement with numerical modeling. Slope and soil nailing stability control are applied following SNI 8460 2017. The average value of the safety factor for the natural slope's stability at the top of the road is 0.269 or less than 1.07 (unstable). Whereas the stability of the lower slope of the road in most locations shows a stable condition (SF>1.25), except for KM 57+100, KM 58+100, and KM 58+900 with an average SF value of 1,183 (critical). The average value of the safety factor for the top slope stability after reinforcement using soil nailing is 1,728, whereas for the lower slope stability is 1,853. Soil nailing is designed as slope improvement at KM 57+900, other than that in anticipation of the potential for landslides at KM 56+900-KM 57+700 and KM 58+100-KM 59+100. The results of all stability control of slope reinforcement using soil nailing have met the SNI 8460 2017 criteria. Therefore, soil nailing can be an alternative solution in dealing or anticipating with landslides on The Piket Nol national route. Key words: landslide, slope stability, safety factor, soil nailing, soil nailing stability.

Abstract

Porous asphalt is a mixture of asphalt with low levels of fine aggregate with the aim of providing a large air cavity, so that high permeability can drain surface water into the soil but has low stability. One of the value effects of stability is the aggregate characteristics, where Banten province has quite a lot of aggregate availability, this is beneficial in reducing the cost of building and rehabilitating roads and overcoming the limitations of road construction materials. This study used a University of New Hampshire Stormwater Center (UNHSC) gradation with three types of porous asphalt mixtures with local aggregates, namely Lebak, Serang, and Merak with variations in asphalt content of 4.5%, 5.0%, 5.5%, 6, 0%, and 6.5%. Based on the results of testing the characteristics of the porous asphalt mixture material which includes aggregate, filler and asphalt meet the specifications of Bina Marga 2018, then from the Marshall test, the Optimal Asphalt Content was obtained by 5.5% for the three types of porous asphalt mixtures where all parameters meet the AAPA requirements. While the highest stability parameters were porous asphalt mixtures using Merak aggregate with low permeability coefficient values for the three porous asphalt mixtures. Keywords: porous asphalt, local aggregate, Asphalt Content, marshall, permeability.

Abstract

The sustainable development concept encourages industrial and business sectors to manage their waste, one of it is the utilization of tailing as infrastructure raw materials for road, bridge, and building. Tailing is included in the category of B3 waste which requires careful handling related to the safety aspect for environment and living beings for its advance used as regulated in PP No 101/2014 and/or PP No 22/2021. This paper examines the characteristics of ModADA tailing aggregate materials from environmental aspect, as one of the materials mixed with tailing and has potential as a raw material for infrastructure in Indonesia. The environmental aspect testing is carried out through TCLP and total metal test. The test result showed the presence of heavy metal content and mercury metal (Hg) concentration in the ModADA tailings material aggregate of 0.570 - 0.825 mg/kg (as for the quality standard threshold for the total metal content of Hg-TK C in PP 101/2014 and PP 22/2021 by 0.3 mg/kg). Considering the possibility of heavy metal toxicity (acute and chronic), it is needed to create an environmental management policy that regulates the utilization of ModADA tailing aggregate material in the cycle of road construction cycle. Keywords: Tailing, ModADA Tailing Aggregate Material, Environtmental, TCLP, Heavy Metal Toxicity
