#3 Limestone (2 - 3")

#3 Limestone (2 - 3") - Technical Overview and Applications

#3 Limestone, also known as #3 crushed limestone, #3 stone, 2"-3" limestone, #3 aggregate, or #3 gravel, is a durable, angular aggregate produced from natural limestone rock. The typical stone size ranges from 2 to 3 inches, though this may vary slightly by supplier. It is gray to off-white in color, heavy, and coarse in texture. This material is usually washed to remove fines and is often free of organic material. It is non-reactive and does not leach harmful chemicals into the environment. #3 Limestone meets ASTM C33 and state DOT aggregate gradation standards when specified, with a bulk density of approximately 1.4 to 1.7 tons per cubic yard.

The angular shape of the stones improves interlocking and load distribution, making #3 Limestone suitable for heavy-duty applications. Its coarse texture and large particle size provide excellent drainage, allowing water to flow through while supporting heavy loads and reducing the risk of rutting or soil displacement. The stone's hardness falls between 3 and 4 on the Mohs scale, ensuring resistance to wear and long-term durability.

Primary Applications of #3 Limestone

• Base material for roads, highways, and large driveways
• Erosion control on slopes, embankments, and as riprap
• Fill for large voids or stabilization of soft ground
• Drainage applications such as French drains, culvert bedding, and backfill behind retaining walls
• Underlay for large slabs or structural foundations
• Gabion basket fill and temporary construction access roads

These uses rely on the stone's ability to provide structural support, resist displacement, and facilitate water movement. #3 Limestone is often specified for construction entrances and tracking pads to reduce sediment movement from job sites.

Limitations and Incorrect Applications

• Not suitable as a finished surface or top layer for driveways, walkways, or patios
• Not appropriate where a smooth, compacted surface is required
• Not intended for use in concrete as aggregate (particle size is too large)
• Not recommended for playgrounds or areas with frequent pedestrian traffic
• Not for fine grading or applications needing tight tolerances

#3 Limestone is too large and angular for walking surfaces and does not compact to create a smooth, dense finish. It is best used as a base layer or for applications where drainage and load-bearing are priorities.

Characteristics and Practical Benefits

The stone's size and angularity allow it to interlock when placed, providing stability for heavy loads. Its low fines content ensures that water can move freely through the layer, making it suitable for drainage and erosion control.

Comparison with Other Aggregates

#3 Limestone is much larger and coarser than #57 limestone or pea gravel, offering superior drainage but less compaction. It is smaller and more uniform than riprap, and unlike recycled concrete, it contains only natural stone.

Payment can be made online using Visa, Mastercard, American Express, Discover, Diners Club, JCB, Apple Pay, Google Pay, or Cash App Pay. Delivery is included in the price, and you can select a preferred morning or afternoon slot. The delivery location must be accessible by a truck with at least 12 feet of road width. The driver will determine the best unloading spot if you are not present. Gravelshop does not spread material on site.

If you are not home at the time of delivery, the material will be left unattended at the specified location, and you accept responsibility for it. For best results, prepare the site in advance and consider marking your preferred drop location. Allow for up to 5% size variation and fines in each load.

Summary of Key Facts

• #3 Limestone is a large, angular, coarse aggregate (2" to 3" size)
• Primary uses: base layers, drainage, erosion control, void fill
• Not for walking surfaces, top layers, or pedestrian paths
• Meets ASTM and DOT standards when specified
• Available for delivery across most US regions with all-in pricing
