A Durability Study of Jute Geotextile Treated with Bitumen Emulsion

ABSTRACT

Jute geotextile is considered as one of the vital construction material. It is also considered as an eco-friendly material but exhibits poor resistance against biodegradation. In the present study, bitumen emulsion was selected for the treatment of jute geotextile, as it prolongs the life of jute geotextile. The Sample of compost was prepared by mixing fertile garden soil, cow dung manure and sand in the proportion of 2:1:1. After the application of compost over jute geotextile, prepared samples were buried under the soil for 21 days. It was found that jute geotextile treated with bitumen emulsion at the rate of 0.6 kg/m² and 0.5 kg/m² revealed 14.49% and 17.03% reduction in strength, respectively, as compared to non-biodegradable samples. Along with this, bitumen emulsion treated (BET) jute geotextile treated with the application rate of 0.6 kg/m² was selected for further research work. Scanning Electron Microscopy (SEM) analysis was also carried, and it was found that there was an improvement in the internal structure of BET jute geotextile as compared to non-treated one. BET jute geotextile in two layers reduced Brittleness Index (IB) considerably. This methodology can be used in the severe earthquake zone for reducing the possibility of enormous damage.

摘要

黄麻土工布是重要的建筑材料之一.它也被认为是一种环保材料但对生物降解的抵抗力很差. 本研究选用沥青乳液处理黄麻土工布延长黄麻土工布的使用寿命. 采用2:1:1比例混合肥土、牛粪、沙制备堆肥样品. 在黄麻土工布上施用堆肥后将制备好的样品埋于土下21天. 结果表明与不可生物降解样品相比沥青乳液处理黄麻土工布的强度分别降低了14.49%和17.03%. 在此基础上选择了沥青乳液处理(BET)黄麻土工布施用量为0.6 kg/m2进行了进一步的研究工作。扫描电镜(SEM)分析表明BET黄麻土工布的内部结构比未经处理的有所改善. 两层BET黄麻土工布显著降低了脆性指数(ib). 该方法可应用于严重地震区以减少巨大破坏的可能性.
