#4 Stone (3/4″ To 1.5″, Modified, Unwashed)
Applications & Uses
#4 Stone, Modified, Unwashed (3/4" to 1.5")
#4 stone in a 3/4" to 1.5" size range, modified and unwashed, is a versatile crushed aggregate commonly used in construction and landscaping. The "modified" designation means this material includes a mix of stone sizes along with fines (smaller particles), which helps it compact well. Being unwashed, it retains natural dust and fines, making it especially suitable for applications where compaction and stability are priorities.
This size and attribute combination is ideal for creating strong, stable bases for driveways, parking lots, and roadways, as well as for backfilling and sub-base layers under concrete or asphalt. The presence of fines allows the material to lock together tightly, reducing voids and providing excellent load-bearing capacity. However, because it is unwashed, it may generate more dust during installation and is less suitable for decorative or exposed surfaces. Overall, #4 modified, unwashed stone is a practical choice for heavy-duty structural applications where compaction and durability are essential.
