Shear Strength of Rockfill, Physical Properties. Engineering Study Number 526.

Abstract

This is a report of the investigation of the relationship between physical properties and two engineering properties; shear strength and consolidation characteristics. Seven rockfill materials were tested using 12-inch diameter specimens with a maximum particle size of 3 or 2 1/2 inches. There was good correlation of shear strength with abrasion loss, hardness, and compressive strength. Strength was proportional to compressive strength and hardness and inversely proportional to abrasion loss. There was good correlation of shape factor and compressive strength with volumetric and axial strain. Materials with high shape factor and compressive strength exhibited lower strain at failure. For consolidation, strain increased with increasing void ratio and decreasing compressive strength and shape factor. For all materials, greater strain occurred in the saturated than in the dry condition. Dry density was proportional to shape factor and specific gravity. (Author)
