Abstract

Di Indonesia ‘small element’ atau paving block, telah banyak dipergunakan sebagai perkerasan jalan atau perkerasan lainnya. Akan tetapi pemakaiannya kebanyakan hanya pada jalan-jalan perumahan yang tidak mempunyai beban kendaraan yang cukup berat. Hal ini disebabkan adanya pengertian bahwa perkerasan dengan paving block tidak mempunyai nilai struktur dan oleh karenanya jalan akan mudah mengalami penurunan jika dipakai untuk jalan dengan beban yang berat. Pada tahun 1976 dilakukan percobaan pembebanan terhadap paving block oleh J. Knapton, seorang pakar dari Cement and Concrete Association dari Inggris. Terbukti bahwa lapis perkerasan jalan dengan paving block mampu menyebarkan tegangan vertical yang timbul akibat beban lapisan lalu-lintas ke lapisan perkerasan di bawahnya dengan baik. Pengalaman di negara-negara yang telah lama menggunakan paving block seperti Belanda, dengan menggunakan bahan lapis pondasi atas maupun bawah (base dan sub-base) serta tanah dasar yang memadai dan memenuhi syarat perkerasan, paving block dapat pula dipakai di jalan-jalan raya dengan beban kendaraan yang berat dengan tidak mengalami penurunan yang berarti.Keywords: Small element (concrete paving block) as a pavement surface layerPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3888[How to cite: Rusbintardjo, G., 2004, Small Element Pavement Structure and Its Deformation Behaviour, Jurnal Media Komunikasi Teknik Sipil, Volume 12, Nomor 3, pp. 60-74]

Abstract

Abstract Several roads in Indonesia are in bad conditions. It is because maintenance works is not properly conducted because of insufficiently, unsustainably, and inconsistency on allocating budget for maintenance. Insufficient or uncertain budgetary allocations to road maintenance have resulted in road deterioration that has significantly increased production and transport costs. To avoid this problem, highway professionals advocate the establishment of dedicated road funds, managed by independent road boards made up of road user representatives. So far roads maintenance in Indonesia is financed using the government budget allocation. It is difficult to give guarantee to the sustainable road maintenance if the finance for road maintenance takes from the government budget allocation. Therefore in this paper will be introduced road fund, the road maintenance funding system widely used in some countries that road conditions can be well maintained. The conclusion is that the road fund needs to be applied to maintenance the road in Indonesia. Keywords: Road, deteriorate, maintenance, road fund, budget system, sustainable  Abstrak Sebagian jalan di Indonesia dalam kondisi buruk. Hal ini disebabkan karena pekerjaan perbaikan  tidak dilakukan dengan baik karena kekurangan, ketidak berkelanjutan, dan ketidak konsistensi dari alokasi dana untuk pemeliharaan jalan. Kekurangan dan ketidak jelasan alokasi pendanaan untuk perbaikan jalan menyebabkan memburuknya kondisi jalan yang menyebabkan peningkatan biaya produksi dan transportasi. Untuk menghindari masalah ini, professional pengembangan jalan raya didorong untuk menciptakan dana jalan secara khusus dan dikelola oleh badan independen jalan yang terdiri dari pemangku kepentingan para pengguna jalan. Sejauh ini, pemeliharaan jalan di Indonesia dibiayai melalui alokasi dana pemerintah. Hal ini menyebabkan sulit untuk memberikan jaminan keberkelanjutan pemeliharaan jalan. Untuk ini, makalah ini mengintroduksi dana jalan untuk sistem pemeliharaan jalan yang umum digunakan di beberapa Negara yang memiliki jalan dalam kondisi terpelihara dengan baik.

Abstract

Buton Natural Rock Asphalt (BNRA) is the only natural asphalt among several  natural asphalt that still  exist and can be explored in the world..  Geological data show that amount 650 million ton of BNRA are found in Buton island. Yet, those amount have not been extensively and maximally used for pavement materials. This paper reported the using of BNRA to modify bitumen to improved the it properties in order resist  the high temperature rutting, and to stabilized clay soil, to  improve their strenght in order suitable to be used as subgrade material. Amount of 15 to 65% of fine BNRA in increments of 5% was added to the bitumen penetration grade 80/100, while amount of 2%, 4%, 6%, and 8% of BRNA by weight of soil were added to the clay soil. Penetration at 25°C and softening point test were conducted to the seven mixtures of BNRA-Bitumen’s to determine the penetration index (PI), the parameter of temperature susceptibility of binder. The results show that the BNRA-Bitumen’s binder has low temperature susceptibility. Use as binder in HMA mixtures also shown that the BNRA-Bitumen’s binder can improve the performance of the mixtures. Marshall Stability and stiffness of the mixtures is higher compare to that of base bitumen binder, especially BNRA-Bitumen’s binder with 50% of BNRA, Marshall Stability reach 2374kg and stiffness 311kg.mm, while HMA mixtures with base bitumen (0% BNRA) only has 1294kg of Marshall stability and 169kg/mm of stiffness. For clay soil stabilization, some tests such as Atteberg Limit, California Bearing Ratio, and direct shear were conducted on clay stabilized BNRA. From the study, it was found that BNRA can improve bearing capacity of expansive clay soil better than the natural sand.

Abstract

Waste Final Disposal (WFD) in some municipals in Central Java Province of Indonesia have brought environmental problem. Evaluation to the environment quality through assessment index of environment risk or Integrated Risk Based Approach (IRBA) need to be carried out to some WFD to be able to make decision which one of WFD can be rehabilitated or must be permanently closed. Aspects of WFD which have to be reviewed include, technical, environment, and social aspect, especially aspect of impact to the society. There are three categories of parameter in analysing IRBA, namely, location criteria which have 20 parameter, waste characteristic have 4 parameters, and lindi characteristic have 3 parameters. To each parameter is provided grade or value and sensitivity index. Research was carried out to five locations of WFD in five municipals, namely, Semarang, Pekalongan, Tegal, Magelang, and Solo municipal. Assessment result to the three categories shows that four WFD namely WFD Pekalongan, WFD Tegal, WFD Magelang, and WFD Solo have risk index value between 300 – 600 and is categorised in fair level of dangerous evaluation, while WFD Semarang have risk index value >600 and is categorised as high level of dangerous evaluation. It can be concluded that the utilization of the four WFD which have risk index between 300 to 600 can be continued and phase by phase can be rehabilitated to become controlled land fill, while for WFD Semarang must be closed immediately because polluted surrounding environment.

Abstract

The performance of pavements is governed by the strength of the subgrade, because subgrade is roadbed soil where the pavement structure is laid. If bearing capacity of the subgrade high, deformation of pavement will not occur and it is not easy to deteriorate. In the contrary, if bearing capacity of the subgrade low, pavement deformation will occur and pavement will deteriorate. This research have objectives to analysis the pavement structure of using existing subgrade soil and using subgrade stabilized with Buton Natural Rock Asphalt (BNRA).  The road connecting Semarang - Purwodadi where always in worst condition was used for study in this research. Semarang – Purwodadi road is laid over montmorillonite expansive clay with lower bearing capacity or have low CBR value only 1 to 2 %. To analysis the pavement structure, both flexible and rigid pavement, AASHTO 1993 pavement design are used. The result show that flexible pavement structure laid over stabilized soil have thinner pavement structure compare to the one laid over the subgrade of original expansive clay soil. Similarly for rigid pavement, the thick of concrete slab over the subgrade of expansive clay is 30 cm, and if laid over the subgrade of stabilized expansive clay with Buton Natural Rock Asphalt (BNRA) is only 25cm. It can be concluded that Buton Natural Rock Asphalt (BNRA), have significant influence to the strength and bearing capacity of expansive clay soil.  Keywords: asbuton, stabilized subgrade, expansive clay soil, AASHTO

Abstract

In flexible pavement, base course is the layer immediately under the wearing surface layer. Because the base course lies close under the pavement surface, it is subject to severe loading. It follows the materials in a base course must be of extremely high quality. To get high quality of base course, research on treated base course with Buton Natural Rock Asphalt (BNRA) have been conducted. Amount of 10, 15, 20, 25, 30, and 35% BNRA by weight of base course aggregate are mixed in the base course aggregate. California Bearing Rasio (CBR) and direct shear test are performed to the mixed of BNRA-base course and also to the original base course to konw how far the influence of BNRA to improve the strength or quality of the base course. The test results show that with BNRA 25% the CBR value can increase from 52.30% to 98%, and cohesion change from 0.127 for original become 0.199 for base course treated BNRA, as well as angle of internal friction (φ) increase from 210 to 430. It can be concluded that BNRA is suitable to use as material for treated base. Keywords: Buton-Natural Rock Asphalt, Treated, Base Course, Improve, Strength.

Abstract:The natural asphalt in the world which can be explored until today is Buton Natural Rock Asphalt (BNRA). The other natural asphalt like Trinidad Lake Asphalt   Based on survey conducted by Directorate General of Mining Ministry of Energy and Mineral Resources Republik of Indonesia, amount of 650 million ton of BNRA are found in Buton island, yet until 92 years since BNRA in Buton Island discover by Hetzel, a Dutch Geolog, only 3.4 ton  that have been explored to be used for road work. This paper reported the using of  BNRA to modify bitumen to improve their properties in order to resist  the high temperature rutting, and to stabilize clay soil, to  improve their strenght. Bitumen penetration grade 80/100 which will be modified was blend by 15 to 65% of BNRA in increments of 5% by weight of bitumen, and to stabilized clay soil, amount of 2% to 8% in increements of 2% BNRA by weight of soil was added. To determine Penetration Index (PI) of neat bitumen and alsobitumen modified with BNRA,  penetration at 250 Celcius and softening point test were conducted. Penetration Index is the parameter to measure the temperature susceptibility of binder. The test results show that ...
