GrinderCrusherScreen, a provider of new and used recycling and aggregate equipment since 1973, has published a detailed guide on crusher run for contractors and construction professionals. The guide covers how to produce, use, and install crusher run as a high-performance base material for driveways, walkways, patios, and commercial projects. The full article is available on the GrinderCrusherScreen blog.

Crusher run is a dense grade aggregate made from a combination of crushed stone and stone dust. The material compacts into a stable, load-bearing base that contractors use under gravel, asphalt, pavers, and concrete surfaces. The guide explains what crusher run is, how it compares to similar products like dense grade aggregate and quarry process, and how contractors can produce it using their own crushers and screens.

The article addresses a gap in available educational content for contractors who want to understand crusher run at a practical level. Most existing resources target homeowners or general consumers. GrinderCrusherScreen built this guide for contractors who handle base preparation, site work, and aggregate production as part of their daily operations.

"We talk to contractors every day who produce their own base material or want to start," said Alex Laldin, Marketing Director at GrinderCrusherScreen. "This guide gives them a clear reference for crusher run production, sizing, depth, and installation so they can make better decisions on their projects and get more value from their equipment."

The guide defines crusher run as a graded mix of crushed stone in sizes from fines up to 1–2 inches, combined with stone dust that fills voids between larger pieces. This combination creates a low-void, high-density base once compacted. The article explains that crusher run, dense grade aggregate, quarry process, and graded aggregate base are common trade names that refer to the same general type of compactable mix used across civil, commercial, and residential construction.

A key section of the article covers mix composition. The guide explains that crusher run depends on a balanced combination of crushed stone and stone dust. The crushed stone provides structure. The stone dust acts as a binder that fills gaps and locks the base together. If the mix contains too much stone and not enough dust, it behaves like clean gravel and does not compact tightly. If the mix has too much dust, the base holds water and loses strength. The article walks contractors through how to recognize and correct these imbalances during production.

The guide also covers common crusher run sizes and typical base depths for different project types. Standard products include 3/4 inch minus and 2 inch minus crusher run, where "minus" means the mix includes all particle sizes from the top stone size down to stone dust. Base depth recommendations range from 3–4 inches of compacted material for walkways and patios, to 6 inches for residential driveways, and up to 8–12 inches or more for heavier commercial applications built in layers.

Contractors will find a dedicated section on using crusher run for driveways, walkways, and patios. The compacted mix holds surface gravel in place on driveways and resists washouts and ruts. Under pavers for patios and walkways, a compacted crusher run base supports the surface, keeps joints tight, and reduces settling over time.

The article includes guidance on estimating material quantities in tons and cubic yards. A typical planning number is about 1.3 tons per cubic yard, though this varies with moisture and stone type. The guide provides a simple volume calculation method using project length, width, and depth in inches, then converting to cubic yards and multiplying by the tons-per-yard factor.

One of the most detailed sections explains how contractors can create crusher run using their own crushers and screens. A primary crusher handles the initial reduction of rock, concrete, or asphalt. Secondary crushers and screens then refine the final sizes and control the ratio of stone to stone dust. Contractors adjust crusher settings and screen openings to produce a graded mix that compacts hard and drains well for specific project conditions. The article also notes that recycled concrete can be processed into a base similar to crusher run, giving contractors an additional material stream and revenue opportunity.

"Our goal is to help contractors get the most out of their business," said Laldin. "Producing your own crusher run with the right crusher and screen setup reduces your dependence on outside aggregate supply, lowers material costs, and gives you direct control over base quality on every project."

The guide closes with best practices for installing a crusher run base. It recommends starting with a firm subgrade, stripping soft material, and correcting any pumping spots before placing base. Contractors should place crusher run in layers, compact each layer to the target depth, and check grade and slope throughout the process. Moisture control is critical so the mix compacts without pumping under the compactor. A properly installed crusher run base provides stable support for gravel, pavers, and concrete, and reduces long-term maintenance on finished driveways, walkways, and patios.

GrinderCrusherScreen sells new and used jaw crushers, impact crushers, cone crushers, trommel screens, incline screens, scalping screens, and conveyors for aggregate and recycling operations. The company helps contractors match equipment to their material type, production volume, and base specifications. With over five decades of experience in recycling and aggregate equipment, GrinderCrusherScreen serves contractors across the United States who produce crusher run, dense grade aggregate, quarry process, crushed stone, and other base materials for construction projects.
