Abstract

Abstrak: Jalan Kumbang merupakan jalan alternatif dari jalan Padjajaran ke Jalan Sancang dan Jalan Lodaya. Kerusakan jalan diakibatkan oleh tingginya lalu lintas kendaraan, banykaknya kendaraan berat yang melintas, juga akibat saluran drainase yang tidak dapat menampung volume air sehingga air melimpas ke jalan. Proses perawatan (maintenance) berupa penambalan dengan aspal (overlay) sudah dilakukan oleh Dinas Bina Marga Kota Bogor akan tetapi hal tersebut belum maksimal. Solusi terbaik adalah dengan metode rigid pavement berdasarkan perhitungan dengan metode NAASRA (1979). Metode perencanaan perkerasan meliputi pengumpulan data primer seperti hasil pengukuran jalan eksisting dan data pengamatan volume lalulintas harian rata-rata, sedangkan data sekunder seperti: data CBR tanah dan data angka pertumbuhan lalulintas tahunan dari DLLAJ Kota Bogor. Berdasarkan hasil perhitungan dengan metode NAASRA, tebal perkerasan minimum yang digunakan adalah 15 cm, digunakan tebal perkerasan sebesar 20 cm. Penulangan menggunakan D12 mm dengan jarak 250 mm dan tulangan melintang tulangan D16 dengan jarak 300 mm. Dowel atau Ruji yang dipakai dengan diamater 250 mm, panjang 450 mm, dan jarak 300 mm, Penulangan tie bar maksimum yang digunakan sesuai metode ASSHTO bila jarak 3 meter dengan besi D12 maka jarak maksimum adalah 120 mm.Kata Kunci: perencanaan perkerasan, tebal perkerasan kaku, metode NAASRA 1979, data lalu lintas harian.Abstract: Jalan Kumbang is an alternative road from Padjajaran Street to Sancang Street and Lodaya Street. Road damage is caused by high vehicle traffic, the large number of heavy vehicles passing through, as well as the drainage channel that cannot accommodate the volume of water so that water spills over to the road.

Abstract

ABSTRACT: Road is the main land transportation infrastructure to move from one place to another places for every traffic user who passes through it, so the volume of vehicles on these roads must be able to be supported by adequate road pavement. Letnan Sukarna road is the connecting access for Rancabungur and Ciampea sub-districts. The existing condition of the road is in the form of Flexible Pavement, however there are several points that can be categorized as moderate to heavily damaged roads. The damage is in the form of longitudinal cracking and potholes that is caused by excessive vehicle loads, malfunctioning of drainage channels and high rainfall. In this study, a comparison of rigid pavement calculations uses the 1993 AASHTO and Bina Marga 2003 methods on Letnan Sukarna Road, Ciampea District, Bogor Regency. This study aims to obtain data on existing conditions and to find out the comparison of rigid pavement thickness. From the calculation results of the AASHTO 1993 method, the thickness of the pavement is 20 cm with transverse connections using dowels with a diameter of 13 mm, length 635 mm, a distance of 1117 mm, a longitudinal connection using a tie bar with a diameter of 25 mm, a length of 450 mm and a distance of 300 mm. Whereas with the Bina Marga 2003 Method, that is obtained a thickness of 18 cm with a transverse connection using a dowel with a diameter of 25 mm, length of 450 mm, a distance of 300 mm, a longitudinal connection using a tie bar with a diameter of 16 mm, a length of 750 mm and a distance of 700 mm. The difference in pavement thickness is quite small, namely 2 cm. It is influenced by differences in the input parameters of the two methods.

Abstract

ABSTRAK: Jalan merupakan prasarana transportasi darat paling banyak digunakan oleh masyarakat dalam melakukan mobilitasnya. Jalan Dramaga merupakan jalan di Kabupaten Bogor yang mempunyai tingkat kepadatan lalu lintas yang tinggi, telah dilakukan pengembangan ruas jalan pada tahun 2018 yang menghubungkan jalan Dramaga dan jalan Ciomas dalam rangka mengurangi kemacetan. Namun ruas jalan alternatif tersebut pada saat ini mengalami kerusakan, jalan alternatif yang mengalami kerusakan adalah ruas jalan Lingkar Laladon. Kerusakan di akibatkan tidak terpeliharanya lingkungan sekitar dan buruknya saluran drainase. Telah dilakukan beberapa kali penanganan dalam perbaikan kerusakan tersebut, namun hasilnya tidak sampai bertahan lama dan rusak Kembali. Oleh karena itu perlu adanya suatu penanganan yang tepat yakni dengan meningkatkan jalan menjadi perkerasan kaku (Rigid Pavement) yang dapat bertahan lama dan melakukan analisis geometric jalan dalam meningkatkan arus lalu lintas. Dalam penelitian ini dihasilkan tebal perkerasan sebesar 20 cm dari hasil perhitungan menggunakan metode AASHTO 1993, dengan tulangan memanjang dan melintang D12-300, dengan sambungan melintang menggunakan dowel yang digunakan diameter 12 dengan Panjang 450mm dan dari hasil analisis geometrik didapatkan 2 tikungan dengan menggunakan jenis full circle yaitu tikungan PI-1 dengan panjang lengkung tikungan sebesar 198,34m, tikungan PI-2 dengan panjang lengkung tikungan sebesar 139,64m. Kata kunci: Perkerasan kaku (Rigid Pavement), geometric jalan, tebal perkerasan  ABSTRACT Roads are the most widely used land transportation infrastructure by the community in carrying out their mobility. Dramaga Street is a road in Bogor Regency which has a high level of traffic density, a road segment has been developed in 2018 that connects Dramaga road and Ciomas road in order to reduce congestion. However, the alternative road is currently damaged, the alternative road that is damaged is the Laladon Ring Road. The damage is caused by the non-maintenance of the surrounding environment and poor drainage channels. Several treatments have been carried out to repair the damage, but the results did not last long and were damaged again. Therefore, it is necessary to have an appropriate treatment, namely by increasing the road into a rigid pavement that can last a long time and conducting a geometric analysis of the road in increasing traffic flow. In this study, a pavement thickness of 20 cm was obtained from the results of calculations using the 1993 AASHTO method, with longitudinal and transverse reinforcement D12-300, with transverse joints using dowels with a diameter of 12 with a length of 450mm and from the results of geometric analysis obtained 2 bends using the full type. circle, namely the PI-1 bend with a bend length of 198.34m, the PI-2 bend with a bend length of 139.64m.

Abstract

Abstract: The deep foundation is one of the most important elements in the construction of high-rise buildings because the weight of the building will be fully borne by the foundation. This study aims to provide an overview of the prediction of the axial bearing capacity of single piles through a mathematical approach based on the results of the tests performed. The design axial bearing capacity is estimated through analysis of soil investigation results (N-SPT test results, DCPT test results, and laboratory investigation results), while the actual axial bearing capacity is obtained through interpretation of the Static Loading Test (SLT) results using the Davisson, Chin, and Mazurkiewicz, and the results of the PDA (Pile Driving Analyzer) load test were analyzed using the CAP-WAP application. The analysis was carried out on single piles with dimensions of 40x40 cm2, located in the Loftville City Apartment development project, South Tangerang City. Based on the results of the analysis that has been carried out, the planned axial bearing capacity is 131.3 tons, while the average carrying capacity based on the results of SLT interpretation on three tested piles using the Davisson, Mazurkiewicz, and Chin methods are 161.7; 205.4; and 98.8 tonnes. The results of the analysis are compared to the results of the PDA test, which shows a bearing capacity value of 290.1 tons, so the BCR values are 65.70% and 45.26% respectively. The BCR value is based on the results of the interpretation of the SLT test successively -respectively by 55.73%, 70.78%, and 34.06%. The BCR value which is not close to 100% may occur due to an error in determining the planned carrying capacity of 131 tons which is far below the actual carrying capacity value based on the PDA test results. The design carrying capacity value is then corrected to 100 tonnes and used as the 100% design load in the static load test so that the interpretation results also show BCR results that are not very accurate.
