Oedometer testing system
-
Testing system (equipped with system for oedometer test of dispersive soils samples) is designed for observation of strength and stiffness properties of dispersed soils in accordance with all systems of standards: GOST, MPH, CRS.
-
Testing in accordance with all systems of standards: GOST, MPH, CRS
-
Parameters of linear-elastic (LE), Cam Clay (CC), and Hardening Soil (HS) models
-
Modularity of ASIS systems makes it possible to use equipment for triaxial and shear tests as well
-
Testing in accordance with GOST, ASTM, BS, ISO, DIN, ЕАС, EN using different techniques:
- confined (oedometric) compression
- compression with lateral stress measurement,
- stress relaxation method,
- CRS method (accelerated compression tests with controlled-strain loading),
- testing with pore pressure control,
- subsidence test,
- free swell index test,
- filtration test (single- or dual-sided filtration) -
Implementation of static and kinematic loading (including stress and strain control)
-
Single- or dual-sided filtration
-
Measurement of sample pore pressure
