Aggregate Base Course, Class 4 Subbase
Aggregate Base Course in a Class 4 size range, designated for subbase applications, is a well-graded blend of crushed stone, gravel, and fines. This material is engineered to provide a stable foundation layer beneath pavements, concrete slabs, and roadways. The Class 4 specification ensures a balanced mix of particle sizes, optimizing compaction and load distribution.
The subbase attribute means this aggregate is specifically formulated to support overlying structural layers by improving drainage and minimizing settlement. Its gradation allows for excellent compaction, reducing voids and creating a dense, stable platform. Common uses include residential driveways, commercial parking lots, road construction, and under concrete pads. Pros include reliable load-bearing capacity and effective moisture control, while the presence of fines may make it less suitable for decorative or exposed applications.Applications & Uses
