Abstract

Kekuatan tanah dasar memegang peranan penting dalam mendukung suatu konstruksi seperti; jalan, bangunan gedung , jembatan dan sebagainya. Dan untuk menilai kekuatan tanah dasar tersebut, dipergunakanlan nilai CBR (California Bearing Ratio). Tetapi seringkali di lapangan, karena keterbatasan transportasi pada daerah pedalaman dan ketersediaan alat pengujian yang cukup memadai, alat yang paling mudah untuk mendapatkan nilai CBR dari tanah dasar tersebut dapat digunakan alat Dinamic Cone Penetrometer (DCP). Dari data pengujian alat DCP tadi, dengan menggunakan fungsi logaritma tertentu sesuai dengan besaran sudut konus dari alat DCP, yaitu 30o atau 60o, yang kemudian digambarkan dalam grafik hubungan antara besaran penetrasi dan jumlah tumbukan, didapatlah besaran nilai CBR. Grafik hubungan yang digunakan adalah perumusan dari Smith dan Pratt, 1983 untuk sudut konus 300 dengan persamaan Log CBR = 2,503 – 1,15 (Log DCP), dan TRL, Road Note 8, 1990, untuk sudut konus 600 dengan persamaan Log CBR = 2,48 – 1,057 (Log DCP). Sebelumnya sudah ada, grafik hubungan DCP dan CBR, akan tetapi untuk menentukan nilai CBR yang dihasilkan, harus menggunakan cara diterawang menggunakan kertas lain, dan hal ini cukup menyulitkan jika titik yang diuji sangat banyak jumlahnya. Dengan perhitungan logaritma yang diaplikasikan ke grafik dan persamaan fungsi, diharapkan dapat mempermudah dan mempersingkat waktu yang dibutuhkan untuk mengolah data DCP yang diuji. Kata kunci : Tanah dasar, grafik DCP, hubungan DCP dan CBR, logaritma DCP

Abstract

One causes of construction failure on flexible pavement is changed composition of the aggregate gradation in asphalt mixture of the plan due to mechanical or non-mechanical process. Aggregates can occur degradation, ie gradation changes due to aggregate breakage of grains. Aggregate degradation can be caused by both mechanical and chemical processes. The decrease in quality occurring in the asphalt mixture is thought to be due to the aggregate gradation change in the asphalt mixture. To find this out, a study on the degradation level of flexible pavement construction is conducted,from Asphalt Mixing Plant to overlay location. Used mixture are Asphalt Concrete-Wearing Course produced by PT. Manggung Polah Raya for location on Sultan Agung Street, Bandar Lampung, Lampung and PT. Rindang Tigasatu Pratama for location on Teuku Cik Ditiro Street, Bandar Lampung, Lampung. Test of samples performed are extraction test and sieves analysis test. From the research result, it is founded that there is degradation during transport of asphalt mixture from Asphalt Mixing Plant to the location. Average degradation percent of location I, location II and location III PT. Manggung Polah Raya and PT. Rindang Tigasatu Pratama is %CA decreased by 5.17%, %FA increased by 3.67% and %filler increased 1.50%. Factors affecting degradation are due to work execution, specific gravity of aggregate and time of transport.Keywords: Road Pavement, Asphalt Concrete, Degradation

AbstractSoil clay have role that very important for something building civil especially in building and projects in whole indonesia. Development construction in soil clay will experience some obstacles as existence settlement and if soil given loading then will occurrence settlement that significant, will reduced volume soil so water pore exit and cause pressure water pore up so experience settlement on consolidation. Then from that need do research settlement that use box and mattress concrete bendrat without pole as tool land subsidence. For knowing how much big function from tool decline this could proven in laboratory with test soil clay in the box and burdened by concrete mattress bendrat and given loading, then do testing settlement or that called consolidation. Giving loading above surface permeability clay aim for look coefficient consolidation (Cv) compression index (Cc) changes in volume (Av) and the coefficient congestion volume (Mv). Result loading settlement clay that use modeling box and mattress bendrat without pole, soft clay soil experience decline 51% while organic clay soil experience decline 56%. Because of organic clay soil have value water content that more high. Research in prove that organic clay soil more fast experience decline compared with soft clay soil when given loading certain.Keywords : clay soil, concrete mattress box test and bendrat without poles, soil consolidationAbstrakTanah lempung memiliki peranan yang sangat penting bagi suatu bangunan sipil khususnya di gedung dan proyek-proyek di seluruh indonesia. Pembangunan kontruksi ditanah lempung akan mengalami beberapa kendala seperti adanya penurunan tanah dan apabila tanah diberi pembebanan maka akan terjadinya penurunan tanah yang signifikan, akan berkurangnya volume tanah sehingga air pori keluar dan menyebabkan tekanan air pori naik sehingga mengalami penurunan tanah secara konsolidasi. Maka dari itu perlu dilakukan penelitian penurunan tanah yang menggunakan box dan matrasbeton bendrat tanpa tiang sebagai alat penurunan tanahnya. Untuk mengetahui seberapa besar fungsi dari alat penurunan ini dapat dibuktikan dilaboratorium dengan menguji tanah lempung di dalam box dan di bebani oleh matras beton bendrat dan diberi pembebanan, kemudian dilakukan pengujian penurunan tanah atau yang disebut konsolidasi. Pemberian pembebanan diatas permukaan tanah lempung bertujuan untuk melihat koefesien konsolidasi (Cv) indeks pemampatannya (Cc) perubahan volume (Av) dan koefesien kemampatan volume (Mv).Hasil pengujian penurunan tanah lempung yang menggunakan pemodelan box dan matras beton bendrat tanpa tiang, tanah lempung lunak mengalami penurunan 51 % sedangkan tanah lempung organik mengalami penurunan 56 %. dikarenakan tanah lempung organik memiliki nilai kadar air yang lebih tinggi. Penelitian ini membuktikan bahwa tanah lempung organik lebih cepat mengalami penurunan dibandingkan dengan tanah lempung lunak ketika diberi pembebanan tertentu. Kata kunci : Tanah Lempung, Box Uji Dan Matras Beton Bendrat Tanpa Tiang, Penurunan Tanah
