Study on characteristics of shear strength of fine crushed stone by automatic shear testing

Abstract

This article focuses on studying the shear strength characteristics of the fine crushed stone based on automatic shear testing, which is an important parameter to evaluate the load capacity of embankment material. The fine crushed stone collected from quarries in Ha Nam province. The shear strength of the material is evaluated according to different levels of compaction, i.e. void coefficient, and cutting speed. The experimental results show that the shear strength of the fine crushed stone is relatively high and confirm that it could be used as a substitute for the river sand in land reclamation.
