Performance Evaluation of Isotropic Spun-bonded Geotextiles for Vacuum Consolidation

In this study, the performance of isotropic spun-bonded geotextiles, which are used in vacuum consolidation, was tested both in the laboratory and in the field. Two kinds of isotropic spun-bonded geotextiles were prepared. One was a matrix/binder structure using low-melting polyethylene terephthalate (PET) copolymer (co-PET) fibers for web bonding. The other consisted of sheath/core (co-PET/PET) fibers. Through the index test, it was seen that the performance of the sheath/core structure isotropic spun-bonded geotextiles was better for use with vacuum consolidation than the matrix/binder structure isotropic spun-bonded geotextiles. However, the drainage performance test, which simulates a construction environment, showed that the sheath/core structure isotropic spun-bonded geotextiles were unstable. The matrix/binder isotropic spun-bonded geotextiles showed better results for the drainage test and the field test results for the matrix/binder isotropic spun-bonded geotextiles showed that they were suitable for use with vacuum consolidation.
