Road Base (Ca-6)

Road Base with Ca-6 Specification

Road Base with a Ca-6 attribute is a versatile aggregate blend commonly used in construction and paving projects. Ca-6 refers to a specific gradation of crushed stone and fines, typically produced from limestone or gravel, that meets state and local standards for compaction and stability. This material is engineered to provide a well-graded mix of coarse and fine particles, ensuring excellent load-bearing capacity and compaction.




The Ca-6 specification is crucial because it balances larger aggregate pieces with fine material, allowing the base to compact tightly and form a stable, durable foundation. This makes it ideal for use under driveways, parking lots, roadways, patios, and sidewalks. Its excellent compaction properties help prevent shifting and settling, while the fines reduce voids and improve stability. However, because of its fines content, Ca-6 road base may not drain as quickly as more open-graded materials, so it is best used where drainage is managed or less critical.
