Electronic Vane Shear Testing

Electronic Vane Shear Testing (eVST) is a widely used method for measuring the undrained shear strength and remoulded shear strength of soil. This technique involves pushing the apparatus into the soil and rotating it, using an electronic motor situated above the vanes, at a controlled rate while measuring the torque required to cause shear failure. eVST is a quick, easy, and non-destructive way to measure soil shear strength. Additionally, eVST is a relatively inexpensive testing method that can be performed quickly on-site, reducing the need for laboratory testing and associated costs.
