Butte Sand and Gravel’s 1½” Class II Aggregate Base is a version of aggregate base that simply contains larger rock than ¾” base. It is a well-graded blend of rock, sand and fines that, when compacted and graded properly, sets up extremely hard. It is typically used in places where you are trying to bridge wet or muddy conditions. It provides an excellent base for roads, driveways, pathways, concrete, or pavers. Butte Sand’s Aggregate Base meets the specifications for Caltrans Section 26 Base. The material is gray in color.
