SHEAR STRENGTH OF UNTREATED ROAD BASE AGGREGATES MEASURED BY VARIABLE LATERAL PRESSURE TRIAXIAL CELL

The angle of shearing resistance increases significantly as the size of the largest particle (maximum in Fuller graded aggregate mixes) is increased. The presence of flaky particles in a Fuller graded mix is not detrimental to its shear strength and may marginally increase it. Material having the highest angle of shearing resistance, suffered the least deformation while material with the lowest angle of shearing resistance, produced the greatest deformation after trafficking for 5 years.
