Home Test Methods Soil Testing Constant rate of Loading (CRL) Consolidation Soil Test Equipment Constant rate of Loading (CRL) Consolidation Soil Test Equipment Provides a controlled ramp of load while the back pressure is maintained. There is also the option to limit the rate of strain if a specified hydraulic gradient across the sample is exceeded. The following soil test equipment can perform the Constant rate of Loading (CRL) Consolidation soil test:- Interface Shear Tester for constant rate of loading (crl) consolidation soil test GDS Small-Strain Hollow Cylinder Apparatus for constant rate of loading (crl) consolidation soil test GDS Consolidation Testing System (Rowe and Barden Type) for constant rate of loading (crl) consolidation soil test GDS Constant Rate of Strain Cell (CRS in Load Frame type) for constant rate of loading (crl) consolidation soil test
