#11 limestone, also known as #11 stone, limestone chips, fine crushed limestone, or small washed limestone, is a clean, angular aggregate commonly used for asphalt, concrete, drainage, surface finishing, and landscaping. It typically consists of small, consistently graded limestone particles around 1/4 inch to 3/8 inch, although exact sizing may vary by quarry and regional specification.
Because #11 limestone is generally washed and contains little to no stone dust or fines, it spreads evenly while allowing water to move through the aggregate. Its fractured edges help the particles settle together and resist movement more effectively than rounded gravel, creating a clean, stable surface with dependable drainage.
#11 limestone is popular for projects that require a finer texture than larger aggregates without using screenings or stone dust. Its manageable size makes it easy to place around pipes, pavement, landscape features, and narrow work areas, while its uniform appearance makes it suitable for both structural mixes and visible finishing applications.
