Abstract

Slag as waste material of steel-making process has similar characteristics with aggregate that has been widely used in pavement construction. The use of slag as chip seal aggregate to provide skid resistance needs to be analyzed. In this laboratory study, the chip seal samples are made using steel slag and natural aggregate. The bonding materials used are asphalt and epoxy resin. Skid resistance tests for all chip seal samples and also hot rolled sheet pavement without chip seal application are performed using the Portable British Pendulum Tester. The results show the variations of chip seal aggregate weight are inconsistent. The natural aggregate used as chip seal material could produce high skid resistance value of 10.3% higher than that using steel slag. Also the skid resistance of chip seal with the ALD 3 mm are not significantly different with that of ALD 6 mm. Similar results occur on the skid resistance of chip seals using epoxy resin and asphalt.Keywords: steel slag, waste material, chip seal, the Portable British Pendulum Tester, skid resistance.

Abstract

One of the root problems causing early damages on provincial and district roads is road administrators’ and developers’ low compliance against the road standards. To deal with this issue, a systemic logic model has been developed to facilitate the monitoring and the evaluation analyses of road standards implementation. The model was written in Java Runtime Environment version 6 and designed to feature portability, acceptability, applicability, and useability. The model was developed based on expert survey and typology analysis to gather and select the determining variables and their indicators.Model application in the case of SNI 03-2853-1992(guidelines on constructing road foundation using crushed stones) implementation is demonstrated in this paper.The results showed 58.50% of the sample “own” the standard, 61.18% “understand” the standard, 60.52% “implement” the standard, 51.39% “oversee” the implementation of the standard, and therefore the overall implementation score for the said standard was 59.08%. The model developed in this study has the potentials to provide recommendations to road administrators on whether or not a standard needs revision or even abolition.Keywords: evaluation, monitoring, quality standard, provincial and local roads

Abstract

Penjabaran agenda kegiatan Rencana Umum Nasional Keselamatan (RUNK) Jalan Indonesia 2011-2035 mengindikasikan adanya upaya pengelolaan risiko kecelakaan lalu lintas secara terpadu. Sayangnya, proses dan hasil pelaksanaan Inspeksi Keselamatan Jalan, yang adalah salah satu agenda unggulan RUNK cenderung bersifat parsial dan subyektif karena tidak tersedianya kriteria obyektif indikator risiko maupun belum optimalnya kinerja kelembagaan penyelenggaraannya. Studi ini dimaksudkan untuk merekomendasikan strategi dan teknik pengelolaan risiko kecelakaan yang lebih terukur melalui penyediaan berbagai indikator risiko kecelakaan beserta teknik penilaiannya. Data dan informasi tentang indikator risiko maupun cara pengelolaan risiko eksisting dikumpulkan lalu dihitung berdasarkan ketersediaan data sekunder dan ditampilkan dalam bentuk matriks indikator maupun nilai risiko. Hasil studi ini menunjukkan bahwa kuantifikasi risiko dan soluasi pengelolaannya secara obyektif hanya dapat dilakukan apabila tersedia indikator risiko yang terukur. Safety factor dan impact speed merupakan indikator peluang dan konsekuensi yang dapat digunakan untuk menentukan nilai risiko kecelakaan. Indikator dan nilai risiko yang ditampilkan dalam paper ini bersifat acuan alternatif. Strategi dan teknik intervensi perilaku pengguna jalan, kecepatan, kinerja infrastruktur jalan, sistem kendali gerak kendaraan dan kelembagaan pengelolaan risiko agar diterapkan secara terpadu dan berkelanjutan. Agar berdampak kumulatif, cakupan pengelolaan risiko hendaknya melingkupi aspek konservasi; pendayagunaan, pengendalian daya rusak dan pemberdayaan sistem keselamatan; hingga perbaikan sistem informasi keselamatan.

Abstract

Thus far, minimum stopping sight distance (SSD) is determined based on design speed, a minimum reaction time of 1.64 s and a deceleration rate of 3.4 m/s², whereas in certain situations the latter can be shorter than 1 s and higher than 4.5 m/s². Awareness of this can trigger speculative behavior, as can be seen from the choice of speed and/or the critical crossing gap, which is often smaller than the recommended minimum SSD. This study focused on the development of an appropriate minimum SSD model that is suited to risky conditions at an un-signalized intersection and its possible usage in accident risk evaluation, particularly for motorcyclists. The data were taken from direct measurements and related studies. Variables that potentially influence minimum SSD were tested. The results strongly suggest that the speed reduction achieved by downshifting significantly influences both the braking distance and the impact speed. Moreover, the minimum SSD obtained from the proposed model significantly differs from that obtained from a similar model recommended by AASHTO. Therefore, it is worthwhile to consider the application of the proposed minimum SSD as an accident probability indicator parameter.

Abstract

Several causes can cause pavement deterioration; a weak subgrade caused one of them. If the pavement construction was built on the weak subgrade, it could damage pavement construction at the top of the subgrade. Chemical soil stabilization with cement and bitumen emulsion is one of the solutions to improve soil bearing capacity for pavement subgrade construction. The purpose of this study was to analyze the potential use of cement and bitumen emulsion as materials of chemical soil stabilization for pavement subgrade construction. In this study, soil samples were mixed by cement (3%, 6%,9%) and bitumen emulsion (3%,6%) and cured for 0, 3, and 7 days. The mixture of soil, cement, and bitumen emulsion was tested for soil bearing capacity and soil swelling by CBR and soil swelling test based on ASTM D 1883-99. Preliminary test results concluded that the original soil is included in class A-7-5 at the AASHTO classification system, and it is dominated by smectite clay minerals so that the original soil is expansive clay soil. The results of the compaction test reveal that soil stabilization with cement and bitumen emulsion can increase the mass of dry density of the soil. They reduce the optimum moisture content, where the variation of 6% cement and 3% bitumen emulsion can increase the mass of dry density by 1,340 gr / cm3 and reduce the optimum moisture content of 25%. The CBR and swelling test also disclose that soil stabilization with cement and bitumen emulsion increases soil bearing capacity and reduce swelling. The highest CBR values (soaked and unsoaked) are found in the variation of 9% cement and 3% bitumen emulsion cured by seven days, where the value is 56.9% (CBR Soaked) and 44.01% (CBR Unsoaked). The variation of 9% cement and 3% bitumen emulsion also can reduce soil swelling, where the value is 0,13%. CBR values at the variety of 9% cement and 3% bitumen emulsion cured by seven days have met the requirements of the road pavement subgrade based on SNI 03-1744-1989. Based on these tests, the cement and bitumen emulsion can use for soil stabilization material for subgrade pavement construction.

Abstract

Public transportation is important in an urban area to provide better mobility and access to several destinations within the city. Therefore, this research was conducted to improve the Trans Jogja service as an Urban Agglomeration Transportation which is considered appropriate for residents, especially students, to ensure they shift to public transportation. The focus of this study was to develop the plan for the route and bus stop distribution in the educational facility covering high schools and universities in Yogyakarta Urbanized Area (YUA). The bus route network plan was formulated based on the number of student trips, land use, characteristics of the road network, route length, and travel time using multi-criteria analysis while the spatial analytical method was applied to cover the bus stop accessibility to schools and universities through two scenarios. The first was approximately a 200-meters radius while the second scenario was a 500-meters radius of accessibility and the route analysis showed the possibility of having 31 new routes of Yogyakarta Urban Agglomeration Transportation to cover the whole sub-districts in YUA including the Godean and Ngemplak which was not previously served by the Trans Jogja. The new routes consist of three outer city routes (OCR), 23 inner-city routes (ICR), and 5 connecting routes for the suburban and urban areas. Meanwhile, the bus stop was planned to focus on the new route as well as residential land use in a sub-urban area, high schools, and universities and the first scenario with a 200-meter radius has 99 units of the additional bus stop while the second with 500 meters has 66 units. This means the second scenario is better due to its coverage of a larger catchment area and other advantages and both the route network and bus stop addition plan were observed to have the equity concept to increase connectivity and accessibility for students.

Abstract

Negative perceptions about accident are usually associated with speeding behavior. However, risk perception has not been considered in accident risk management. It is accepted as a personality matter, thus the number of accidents per year was used as accident risk tolerance indicator. Consequently, due to insufficient measurable indicators, it would be difficult to prevent the increasing speeding behavior. This paper discusses the improvement of accident risk tolerance indicators, i.e. safety factor and margin of safety, and their possible usage in speed management policies. These indicators were built based on the correlation between the results of interview and braking maneuver test. From this combine approach, using aggregated-individual and expert acceptance models, it was found that risk tolerance arose because motorcyclists accepted both the advantages and disadvantages gained from speeding, obtained through their riding frequency, duration of riding and/or accident involvement experienced. However, inappropriate speed due to miss-perception toward braking capability should be avoided. Inversely, an appropriate speed management should consider their travelling expectation

Abstract

The increase in population and economy is in line with the demand for movement to palu area and also from Palu to other areas using air transportation. Mutiara Sis Al Jufri Airport is one of the gateways to Central Sulawesi. Therefore, runway pavements should be able to receive the largest planned aircraft from the farthest planned route. This study aims to analyze the geometric development of runway pavement of Mutiara Sis Al Jufri Airport. The process of geometric analysis of runways using the ICAO (International Civil Aviation Organization) method using Boeing 737-900 ER as a planned aircraft, the results of the analysis were then evaluated against the existing geometric conditions of runway pavement Mutiara Sis Al Jufri Airport. Based on the results of the analysis obtained the results of the length of the runway with boeing 737-900 ER planned aircraft of 3019 m. Therefore, it is necessary to development on the runway of Mutiara Sis Al Jufri Airport of 769 m in order to serve the plan aircraft optimally without any restrictions on the weight of the aircraft. At runway width, runway shoulder, runway strip, RESA and stopway do not need to be developed because it has met ICAO rules.
