Butte Sand and Gravel’s 1” Minus Shoulder Backing is a sandy base material used by Caltrans and other public works agencies on the shoulders of freeways and highways. It compacts easily when a roller or other compaction equipment are used, and gets extremely hard. It tends to be dusty when dry. The material is gray in color.
