Abstract: Use of synthetic geotextile for embankment stabilization, reinforcement of soil, grade separation of road layers is a common practice for many years. Woven Synthetic geotextiles are not environmental friendly and as imported these are often found to be costly. Jute geotextiles (JGT) are indigenous and have got enough potential for use as initial reinforcement and moisture absorption accelerator in road subgrades, for river bank protection via facilitating establishment of inverted filter formation and for top soil erosion control of exposed slope surfaces. By employing different modification techniques, JGTs may be converted into designed biodegradable material without changing its environmental friendly properties. In the present study two types of JGTs (untreated 627gsm and untreated 724gsm) have been used. The samples are supplied by Bangladesh Jute Mills Corporation (BJMC) and Bangladesh Jute Research Institute (BJRI). The most important properties of JGT, i.e., tensile strength and strain at maximum load have been evaluated for both types of samples at different strain rate. This paper presents the rate sensitivity of JGT through the test results of these two types (untreated, 627gsm and untreated 724gsm) of JGTs.
Keywords: Jute geotextiles (JGT), uniaxial tensile strength, strain, strain rate sensitivity.
