#1 Stone, Modified, 1.5" to 3.5"

#1 Stone in a modified form, sized from 1.5" to 3.5", is a large, crushed aggregate commonly produced from durable natural rock. The "modified" attribute means this material includes a mix of stone sizes along with fine particles, resulting in a well-graded blend that compacts tightly.

The larger size range provides excellent load-bearing capacity and stability, making it ideal for heavy-duty applications such as base layers for roads, parking lots, and large driveways. The inclusion of fines in the modified mix enhances compaction, reducing voids and creating a solid foundation that resists shifting and settling. While its coarse texture is not suitable for decorative or surface use, it excels as a structural base where strength and durability are priorities.
