— The most common technique is non-open graded base. What this means is that the compacted granular base portion of the job is using a 3⁄4" Crusher Run Gravel (also called Granular "A"). This is a combination of angular 3⁄4" stone mixed with fines and when compacted this material creates a solid base for the next step; the bedding course.
