    Abstract

    Teknik penstabilan cerun telah menjadi satu subjek penting dalam bidang geoteknikal. Pada masa ini, terdapat beberapa kejadian tanah runtuh di serata dunia. Dalam usaha untuk meningkatkan kestabilan cerun, begitu banyak jenis tetulang cerun telah dihasilkan sejak kebelakangan ini. Antaranya, tayar sekerap telah menunjukkan beberapa ciri yang dikehendaki untuk teknik penstabilan cerun. Kerana jumlah tayar dihasilkan melebihi jumlah tayar sekerap dikitar semula setiap tahun, ia adalah satu peluang yang baik untuk menyelesaikan masalah alam sekitar ini pada masa yang sama meningkatkan kestabilan cerun apabila ia digunakan dalam bidang geoteknikal. Dalam kajian ini, cerun prototaip diperkukuhkan dengan system 8R telah dibina pada 15 Disember 2014 untuk mengkaji prestasinya. Hamparan 8R ini dihasilkan menggunakan tayar berbentuk lapan. Bagi tujuan analisis, ujian tegangan, tarik keluar dan paksi telah dijalankan ke atas tayar sekerap untuk menentukan sifatnya. Kekuatan tegangan sampel adalah lebih rendah pada sampel jalur membandingkan sampel 8R kerana keadaan wayar yang terganggu. Keputusan menunjukkan bahawa daya Tarik keluar dipengaruhi oleh bentuk, bilangan tetulang, saiz, beban tambahan dan juga bahan isian. Jeleketan ketara menunjukkan peningkatan dengan peningkatan nombor sambungan. Dari hasil analisis cerun, ia menunjukkan bahawa dengan memasang hamparan 8R kestabilan cerun telah bertambah baik. Dari hasil pemantauan, ia menunjukkan bahawa system hamparan 8R akan menghasilkan dinding penahan yang mempunyai pengaliran yg baik, kekuatan tinggi dan ringan. Oleh itu, dengan menggunakan sistem hamparan 8R sebagai struktur penahan akan menghasilkan dinding penahan yang diingini dan pada masa yang sama membantu dalam mengurangkan jumlah tayar sekerap yang ada. ________________________________________________________________________________________________________________________ Slope stabilization technique is become an important subject in the geotechnical field. Currently, there are a number of landslide occurrences around the world. In order to improve the slope stability, so many types of slope reinforcement had been produced lately. Among these, scrap tyre had been showing some desired properties for slope stabilization technique. Since the amount of generated tyre exceeded the amount of scrap tyre recycled annually, it is a good opportunity to solve this environmental problem at the same time enhancing the slope stability when it is used in geotechnical field. In this research, a prototype slope reinforced with 8R mat system was constructed on 15th December 2014 to study its performance. This 8R mat was produced using 8 shape tyre. For the analysis purposes, the tensile, pull-out and axial test were conducted on the scrap tyre to determine its properties. The tensile strength of the sample was lower on strip sample compared to 8R sample due to disturbed wire condition. The result shows that the pull-out force was influenced by the shape, number of reinforcement, size, overburden load and also the fill material. The apparent cohesion shows an increase with the increase of connection number. From the slope analysis result, it shows that by installing the 8R mat the slope stability had improved. From the monitoring results, it shows that the 8R mat system will provide a retaining wall that have better drainage, high strength and lightweight. Thus, by using the 8R mat system as a retaining structure will provide a desirable retaining wall at the same time help in reducing the amount of scrap tyre available.
