#131 Screenings (3/8" Minus) - Crushed Stone with Fines

#131 Screenings, also known as 3/8" minus, 3/8" screenings, #131 crusher run, or 3/8" minus gravel, is a compactable aggregate made from crushed stone. The material contains stone particles up to 3/8 inch (about 9.5 mm) in size, along with smaller fines. These fines help the material lock together and compact into a firm, stable base. The stone is usually sourced from limestone, granite, or trap rock and is mechanically crushed to meet industry standards. #131 Screenings typically appear gray or the natural color of the parent rock and are free from organic debris.

Physical Properties and Standards

The product features a rough, angular texture for improved compaction and stability. The fines fill gaps between larger particles, which helps the material compact to a hard surface. This structure provides moderate drainage but retains some moisture-making it less suitable for high-drainage applications. The bulk density is approximately 1.5 to 1.7 tons per cubic yard. It meets ASTM D448 No. 4 or No. 5 gradation standards, but the specific gradation can vary by supplier. #131 Screenings are typically pH neutral to slightly alkaline, depending on the stone type, and meet local Department of Transportation or construction material standards for use as a base material.

Common Applications

#131 Screenings are widely used in construction and landscaping projects where a compacted, stable base is needed. Typical applications include:

• Base layers for driveways, patios, and walkways
• Sub-base for asphalt or concrete paving
• Fill material for drainage and erosion control
• Under pavers or flagstones to provide stability
• Backfill around pipes or retaining walls
• Temporary construction roads or access paths
• Base for playgrounds or sports fields

Its ability to compact tightly makes it effective for supporting surface structures. However, the presence of fines means it is less permeable than clean stone and not suitable for applications that require rapid drainage.

Installation and Handling Guidelines

Proper installation is critical for best performance. The subgrade should be cleared of organic material and debris, then graded for water runoff. Screenings should be applied in layers no thicker than 4 inches, with each layer compacted thoroughly using a vibratory plate compactor or roller. Multiple passes are recommended for high-traffic areas. For projects sensitive to water accumulation or frost heave, a dedicated drainage layer beneath the screenings is advised.

Material Limitations and Proper Use

#131 Screenings are not recommended for areas where rapid water drainage is required, as the fines reduce permeability. The material is not intended for decorative surface use, as the fines can become dusty or muddy if not properly compacted. It is also not suitable for applications requiring large, clean stone without fines.

Alternative Names and Regional Variations

• #131 Crusher Run
• 3/8" Minus Crusher Run
• Crusher Fines (may vary by region)

These terms may refer to similar materials, but local specifications and stone types can result in performance differences. Always confirm the gradation and composition with your supplier for critical projects.
