Road Base (Class 4 (1.5″)
Applications & Uses
Road Base in Class 4 (1.5") Size Range
Road base in a Class 4 (1.5") size range is a foundational construction aggregate composed of crushed stone, gravel, and fines. This material is engineered to provide a stable, load-bearing surface for a variety of construction projects. The 1.5" maximum particle size ensures a robust blend that compacts well, creating a dense, durable base layer.
The larger Class 4 size is ideal for heavy-duty applications where strength and stability are critical, such as under roadways, parking lots, and driveways. Its coarse texture allows for excellent drainage while still locking together tightly when compacted, reducing the risk of shifting or settling over time. While the larger aggregate size may make it less suitable for top layers or decorative use, it excels as a sub-base material, supporting both residential and commercial projects that require long-lasting performance.
