The study investigates possible effects of stress path on a series of consolidated-drained triaxial compression and extension tests. Test results of unreinforced and reinforced residual soil simulating the different loading path similar to what is expected in the field. The testing program concentrated on the study of normally consolidated on 100 mm diameter and 200 mm high specimens. Testing was carried out at consolidating pressures ranging between 0.10–0.60 MPa using GDS computer control triaxial apparatus. The Cam-Clay model parameters for unreinforced and reinforced residual soil were determined based on isotropically consolidation and drained shear test results. Computations were performed using the model constant and finite element software SIGMA/W to predict the stress-strain response for different consolidation pressure and stress path tests. Predicted results were compared with measured response to assess the validity of the model parameters. The model prediction was found to yield acceptable results and is quite effective in demonstrating the effects of stress paths, effective stresses and strains of reinforced soil composites.
