Crushed Stone: Your 2016 Product Guide

Crushed stone is a staple for contractors, homeowners and businesses across NJ and the northeast. The aggregate stone materials can be used both for decorative or practical functions, making them extremely versatile and high in demand.

However, having so many different types of crushed stone available for purchase and use can make it difficult for customers to feel confident about which material is best suited for their specific project demands.

After all, not all rock is created equal and each type comes with its own unique set of advantages and considerations.

The purpose of this post is to highlight the various crushed stone materials that will be available to consumers in 2016 so that you can gain a better understanding of which types should be used for certain projects.

Crushed Stone

Crushed stone is harvested, crushed, reduced in size and screened based upon the size requirements of the material. Typically, you will find crushed stone sold at 3/4″, 1 1/2″ and 2 1/2″ in size. Depending on the quarry, crushed stone could be comprised of granite, gneiss, trap rock or limestone. All of these materials are perfectly suited to fulfill a range of functions.

Typically, crushed stone is used as a base material in construction projects. Larger pieces may be used to fill in the foundation of a new building, whereas medium and smaller crushed stone could be used as the base for roads, driveways, walkways, etc. Crushed stone might also be purchased and used as railroad ballast. Finally, crushed stone can be used in the generation of portland cement and aglime.

Washed Clean Stone

Washed clean stone is a crushed stone aggregate material that has been reduced to very small sizes (generally 1/4″ or 3/8″ depending on the manufacturer), screened and thoroughly washed to ensure that there is no remaining stone residue or dust.

Although the material can certainly be used to create ready-mix concrete and railroad ballast, its most common usage is in drainage applications. The small size of the stones makes it perfect for allowing healthy percolation to occur as water makes its way back into the groundwater supply.

In addition to this, you might find that homeowners enjoy using this type of crushed stone in the surfacing of paths and loose-fill driveways, or even as an alternative to organic mulch.

Pea Gravel

After crushed and washed clean stone, pea gravel is one of the most commonly selected crushed stone materials that can be used for decorative or functional applications. Pea gravel is characterized by its small, rounded nature and its wide range of different colors.

The stones may feature shades of white, tan, brown, gray, blue, red and green. This all adds to its visual appeal. Because the stones are so smooth, they are soft and easy to walk on or drive across. This makes them ideally suited for surfacing paths, walkways and even driveways.

Pea gravel is also very shock absorbent. This is why some parks, schools and day cares choose to surface their playgrounds with the round gravel. Finally, pea gravel promotes very healthy drainage, eliminating any problems associated with flooding or pooling.

White Marble Chips

White marble chips are among some of the most unique and interesting types of crushed stone available. Although the name might indicate that the rocks are purely white in color, this is a misnomer.

Although the stone does feature shades of white, true white marble chips are also marked with a streak of gray. Another identifying feature of these special stones is the glittery, shimmering surface. This is what makes the material so perfect for reflecting light away from a surface.

It’s for this very reason that white marble chips are frequently spread on rooftops. Beyond this, however, marble chips might also be used as an alternative to traditional organic mulch, in the creation of walking paths or as an edging material along driveways, walkways, gardens, etc.

Riprap Stone

Riprap stone may be required by counties and cities along major rivers, streams, lakes and ponds. Riprap stone is available in various sizes (usually 4-9″), but tends to be larger and heavier than most other crushed stone types because it is intended to prevent shoreline erosion.

As water continues to lap up against the shore and flow along, it will begin to erode the soil and land along the edges. Riprap works to protect these areas, stabilizing and restoring embankments. Riprap can also be used to deter people from wandering too close to areas where dangerous currents may frequently occur.

In addition to all of this, riprap stone is frequently selected in back filling projects and in the construction of gravity retaining walls.

Quarry Process

Sometimes referred to as dense grade aggregate (DGA) or crusher run, quarry process is a very popular choice for those who are looking for a base or surfacing material that will become very compact and semi-permenant.

Quarry process is stone aggregate that has been crushed and screened through a 1″ screen. It typically features very jagged edges, which helps the materials create compaction and traction. A specific ratio of stone dust fines are also introduced to the mix, which helps to fill in the voids and allows the stone to further bond together.

This creates an extremely firm and sound base for a variety of different construction projects. It also enables users to construct semi-permenant roads and driveways that will not kick up a lot of dust.

Stone Dust

Stone dust is sometimes known as stone screenings and is simply a very fine layer of pulverized stone. Stone dust offers very good traction, which can work to hold stone pavers in place in lieu of sand or other base materials.

It may also be used to reduce the void content between rocks and other loose-fill materials to ensure adequate compaction and cohesion.

Stone Grits

Stone grits are screened down to 2×4 mm. These grits are used during the winter months when traction needs to be improved on slick and icy roadways and similar surfaces. It is also often mixed into sealers and applied to stone surfaces to add esthetically pleasing textures and safe traction.

Tips For Buying Crushed Stone in NJ

Once you’ve determined which type of crushed stone you’d like to purchase, it’s important that you know where to go to buy the very best materials. While some big box retailers carry crushed stone, you should think twice before taking your business there. These retailers don’t manufacture their own stone, which creates several problems.

First, the store has no control over the manufacturing processes used and cannot guarantee quality. Secondly, the retailer may not be familiar with the stone’s composition or origins. Lastly, the vendor will need to resell the crushed aggregate at a higher rate than what it’s worth.

For the very best crushed stone at the fairest and most competitive prices, it’s wise to look for a local stone manufacturer and supplier like Braen Stone. We’ve been operating our own quarries for more than a century, building a solid reputation on quality, reliability, and customer care.
