#89 Limestone Pea Gravel (S1B DOT) (3/8")

#89 Limestone Pea Gravel (S1B DOT) (3/8") - Product Overview

#89 Limestone Pea Gravel, also known as 3/8" Limestone Pea Gravel, Pea Gravel Limestone, S1B DOT Limestone Pea Gravel, or DOT Pea Gravel, is a uniform, fine aggregate composed of crushed limestone. Each stone is approximately 3/8 inch in diameter, offering a consistent, pea-sized gradation. The material is typically light tan to gray in color, reflecting the natural hues of limestone. Its rounded, smooth texture results from the crushing and washing process, which also minimizes dust and fines. This gravel is known for its durability, high hardness, and resistance to weathering and erosion. It is non-toxic, environmentally friendly, and meets Department of Transportation (DOT) S1B specifications for size and quality.

Key Characteristics

• Size: Uniform 3/8 inch nominal diameter
• Material: 100% crushed limestone, washed for cleanliness
• Color: Natural tan to light gray
• Density: Approximately 100-110 lbs per cubic foot (varies by moisture)
• pH: Neutral to slightly alkaline
• Meets S1B DOT classification for road and construction use

Practical Applications and Limitations

#89 Limestone Pea Gravel is primarily used as a top layer for ground covers in landscaping and construction. Its fine, rounded stones provide good drainage and surface stability, making it suitable for walkways, patios, decorative garden paths, and playground surfaces. The uniform size supports effective water runoff, reducing surface erosion and water accumulation. In construction, it serves as a drainage layer, aggregate in concrete and asphalt mixes (where specified), and for small-scale erosion control. It is also used for railroad ballast in limited cases and as a DOT-approved material for road shoulder and sub-base stabilization.

Due to its fine size, #89 Limestone Pea Gravel is rarely used as a primary base material for heavy load-bearing applications. For such uses, an underlying reinforced or coarser base is required. The gravel's angular shape allows for compaction and interlocking, but repeated freeze-thaw cycles or high-traffic areas may require periodic replenishment. It is not ideal as a sole base in locations with poor drainage preparation.

Common Uses

• Top layer for decorative landscaping, garden paths, and playgrounds
• Drainage layers in construction and landscaping
• Base material for patios, walkways, and driveways (as a top layer)
• Aggregate in concrete and asphalt mixes (as specified)
• Erosion control in small-scale applications
• DOT-approved road shoulder and sub-base stabilization
• Aquariums and water features due to inert, non-toxic nature

Specifications and Standards

Installation and Usage Guidelines

For best results, prepare the site by excavating to the desired depth and installing a compacted subgrade or crushed stone base. Place #89 Limestone Pea Gravel in layers no thicker than 3 to 4 inches, compacting each layer to stabilize the surface and prevent settling. Edge restraints, such as metal or plastic borders, help contain the gravel and maintain a clean finish. The product's fine size and angular shape make spreading and raking straightforward, but may require more effort compared to rounded gravels. In areas with frequent foot or vehicle traffic, periodic replenishment may be necessary to maintain coverage and function.

#89 Limestone Pea Gravel is not designed for heavy-duty base applications or locations subject to repeated freeze-thaw cycles without adequate drainage. It is best used as a top layer or decorative cover, providing both aesthetic value and practical function.
