1. Introduction

The solid volume ratio is an important design index of the graded crushed stone, which is generally considered to be related to the permanent deformation and resilient modulus. In the technical guidance in Fujian Province [ 30 ], the solid volume ratio should be larger than 85% based on the modified Proctor compaction method.
