Geotekstil ve Palmiye Ağacı Budama Atıklarının Kum Zeminde CBR Değerine Olan Etkisinin Karşılaştırılması

Abstract

In recent years, geosynthetics have been widely used as soil improvement agent. Geotextiles, one of the types of geosynthetics, are mostly used for enhancing the bearing capacity of soils in addition to their functions such as separation, filtration, and drainage. In the current study, the usability of palm tree pruning waste which is inconvenient to store and dispose of as an alternative to geotextile was investigated by conducting a series of CBR tests. Experiments were carried out on geotextile-reinforced and palm-reinforced sand in CBR mould at different burial depths. In addition, an unreinforced test was conducted for comparison purposes. In the light of the test results, an apparent improvement was observed in CBR values as compared with unreinforced case. CBR values obtained in these tests reinforced with geotextile and palm tree pruning waste were found to be close to each other. Therefore, it is understood that palm tree pruning waste is able to be used as an alternative to geotextile by getting rid of waste material. Additionally, its easy applicability makes it more attractive to use palm leaves in soil improvement.
