Home Test Methods Soil Testing RAMP and CYCLE pressure or volume change (Saturation Ramp) Soil Test Equipment RAMP and CYCLE pressure or volume change (Saturation Ramp) Soil 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 soil test equipment can perform the RAMP and CYCLE pressure or volume change (Saturation Ramp) soil test:- Unsaturated Back Pressured Shear Box for ramp and cycle pressure or volume change (saturation ramp) soil test Hydraulic Load Frames for Rock for ramp and cycle pressure or volume change (saturation ramp) soil test 1000kN (1MN) / 2000kN (2MN) Static Compression Only Loadframe for ramp and cycle pressure or volume change (saturation ramp) soil test Back Pressure Shearbox - High Pressure for ramp and cycle pressure or volume change (saturation ramp) soil test Environmental Triaxial Testing System for ramp and cycle pressure or volume change (saturation ramp) soil test Dynamic Back Pressure Shearbox for ramp and cycle pressure or volume change (saturation ramp) soil test Interface Shear Tester for ramp and cycle pressure or volume change (saturation ramp) soil test Environmental Triaxial Automated System for ramp and cycle pressure or volume change (saturation ramp) soil test GDS Small-Strain Hollow Cylinder Apparatus for ramp and cycle pressure or volume change (saturation ramp) soil test GDS Back Pressured Shear Box for ramp and cycle pressure or volume change (saturation ramp) soil test GDS Constant Rate of Strain Cell (CRS in Load Frame type) for ramp and cycle pressure or volume change (saturation ramp) soil test GDS Consolidation Testing System (Rowe and Barden Type) for ramp and cycle pressure or volume change (saturation ramp) soil test Resonant Column Apparatus (Stokoe Type) for ramp and cycle pressure or volume change (saturation ramp) soil test GDS True Triaxial Apparatus for ramp and cycle pressure or volume change (saturation ramp) soil test GDS Large Diameter Cyclic Triaxial Testing System for ramp and cycle pressure or volume change (saturation ramp) soil test Advanced Dynamic Triaxial Testing System for ramp and cycle pressure or volume change (saturation ramp) soil test GDS Enterprise Level Dynamic Triaxial Testing System for ramp and cycle pressure or volume change (saturation ramp) soil test Hydraulic Load Frames for Soil for ramp and cycle pressure or volume change (saturation ramp) soil test Virtual Infinite Stiffness Load Frames for ramp and cycle pressure or volume change (saturation ramp) soil test Triaxial Automated System (Load Frame type) for ramp and cycle pressure or volume change (saturation ramp) soil test Triaxial Testing System (Automated Stress Path type) for ramp and cycle pressure or volume change (saturation ramp) soil test
