Generally, as the grade number goes up, the size of the stone goes down. #1 – The # 1 crushed stone grade is the largest of the crushed stone grades and includes stone between 2-4 inches long. This material is great for larger jobs or for filling in larger holes. #3 – This size of the stone ranges from 1/2 to 2 inches long.

The nominal maximum size (largest sieve size retaining more than 10 percent of the aggregate) for the different the three commonly used grades is as follows: Grade 3 – 1/2 inch. Grade 4 – 3/8 inch. Grade 5 – No. 4 or 1/4 inch for 5S. A successful seal coat is more achievable when large size cover aggregate is used. This is
