Home Test Methods Rock Testing RAMP and CYCLE pressure or volume change (Saturation Ramp) Rock Test Equipment RAMP and CYCLE pressure or volume change (Saturation Ramp) Rock Test Equipment Saturation ramp allows you to independently increase or decrease the Cell Pressure and the Back Pressure. The saturation ramp is used to steadily change the pressures in the system either keeping a constant effective stress or change to a desired effective stress. The following rock test equipment can perform the RAMP and CYCLE pressure or volume change (Saturation Ramp) rock test:- Unsaturated Back Pressured Shear Box for ramp and cycle pressure or volume change (saturation ramp) rock test Hydraulic Load Frames for Rock for ramp and cycle pressure or volume change (saturation ramp) rock test 1000kN (1MN) / 2000kN (2MN) Static Compression Only Loadframe for ramp and cycle pressure or volume change (saturation ramp) rock test Back Pressure Shearbox - High Pressure for ramp and cycle pressure or volume change (saturation ramp) rock test Environmental Triaxial Testing System for ramp and cycle pressure or volume change (saturation ramp) rock test Dynamic Back Pressure Shearbox for ramp and cycle pressure or volume change (saturation ramp) rock test Interface Shear Tester for ramp and cycle pressure or volume change (saturation ramp) rock test Environmental Triaxial Automated System for ramp and cycle pressure or volume change (saturation ramp) rock test GDS Small-Strain Hollow Cylinder Apparatus for ramp and cycle pressure or volume change (saturation ramp) rock test GDS Back Pressured Shear Box for ramp and cycle pressure or volume change (saturation ramp) rock test GDS Constant Rate of Strain Cell (CRS in Load Frame type) for ramp and cycle pressure or volume change (saturation ramp) rock test GDS Consolidation Testing System (Rowe and Barden Type) for ramp and cycle pressure or volume change (saturation ramp) rock test Resonant Column Apparatus (Stokoe Type) for ramp and cycle pressure or volume change (saturation ramp) rock test GDS True Triaxial Apparatus for ramp and cycle pressure or volume change (saturation ramp) rock test GDS Large Diameter Cyclic Triaxial Testing System for ramp and cycle pressure or volume change (saturation ramp) rock test Advanced Dynamic Triaxial Testing System for ramp and cycle pressure or volume change (saturation ramp) rock test GDS Enterprise Level Dynamic Triaxial Testing System for ramp and cycle pressure or volume change (saturation ramp) rock test Hydraulic Load Frames for Soil for ramp and cycle pressure or volume change (saturation ramp) rock test Virtual Infinite Stiffness Load Frames for ramp and cycle pressure or volume change (saturation ramp) rock test Triaxial Automated System (Load Frame type) for ramp and cycle pressure or volume change (saturation ramp) rock test Triaxial Testing System (Automated Stress Path type) for ramp and cycle pressure or volume change (saturation ramp) rock test
