the complete guide to crushed stone and gravel

the complete guide to crushed stone and gravel

In this article, we are going to take a deep dive into the types of crushed stone and gravel, how they are made, and their basic applications. You may not be a quarry expert at the end, but you will understand the basics for your next concrete or hardscaping project!

Most crushed stone is produced in quarries and is crushed when machinery breaks up and crushes larger rocks. Instead of being shaped or formed naturally, such as in a riverbed or canyon, crushed stone is produced with man-made machinery and processes.

It begins with using a rock crusher in a quarry or site with plenty of large rocks. There are many types of crushers, but their main job is the same: Crush larger rocks into smaller pieces to be used for construction material.

Crushed stone is then passed through different screeners to be organized and stored in different piles according to their size. The screening process starts by removing larger stones, then medium stones, and eventually goes all the way down to the stone dust.

This screening is important because contractors need very specific types of crushed stone to complete different types of projects. For example, you dont want large stones in ready mix concrete, and you dont want stone dust in drainage systems.

After being sorted into different piles depending on the size of the stone, the stone is ready to be shipped from the quarry. Quarries deliver directly to job sites, to concrete plants, or to wholesale distributors who sell the stone through retail to customers.

Because large stones and quarries are hard on tires and require heavy metal, crushed stone was hard to make and transport until heavy machinery with tracks was developed. WW2 expedited the development of this machinery, and crushed stone began to be widely used in construction projects in the 1940s and 1950s.

Large-scale building projects, particularly in infrastructure like the Eisenhower Interstate System, helped usher in an era where crushed stone was used in almost every part of construction. Foundations, concrete, drainage systems, and roads were all needing large quantities of crushed stone.

An example of this often occurs when a road is being replaced or resurfaced. Many road construction companies are beginning to grind and crush the existing road as they remove it. This crushed road, which is essentially crushed stone, then becomes the base for the new road.

The exact amount of crushed stone recycling is unknown due to a lack of reporting. Much of the crushed stone is also recycled right on the construction site, especially with road construction, and this makes it difficult to measure.

The most common use for recycled crushed stone is as a base for roadways, especially when the old road can be torn up, crushed, and reused. Concrete blocks and bricks can also be crushed and recycled as a base.

Crushed stone often has an angular and jagged edge that occurs during the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to the effects of running water.

Metamorphic: Metamorphic rocks become changed through intense heat or pressure. Similar to clay hardening in an oven, metamorphic rocks become very hard and crystallized by intense or heat or pressure.

If you go to a creek or river, you see all types of rocks, both large and small. These larger rocks can be used for foundations or other building projects, but typically gravel is screened and only the smaller pieces are used.

Pea gravel: Pea gravel is some of the smallest gravel - typically or smaller in size. Pea gravel is often used in places like fish tanks, walkways, swimming pools, or other places where foot traffic occurs or small gravel is needed.

When thinking of construction, it is important to know what kinds of rock are ideal for specific applications. After all, if a rock type crumbles easily under pressure, you dont want to use it as a component in ready mix concrete or pavement.

Granite: An igneous rock that is durable and is easily polished. Because of the color, grain, and polishing ability; they are often used inside homes for countertops or on the outside of monumental or civic buildings. However, they can also be used on bridge piers and river walls.

Limestone: A sedimentary rock that is the most commonly used to make crushed stone in the United States. One of the most versatile rocks for construction, limestone is able to be crushed easily making it a primary rock used in ready mix concrete, road construction, and railroads. It is widely available in quarries across the country.

Slate: A metamorphic rock typically found in layers. Because it is easily mined and cut in these natural layers, it works well in applications requiring thin rock layers. Common examples are roofing tiles, certain types of chalkboards, gravestones, and some pavement applications.

Laterite: A metamorphic rock with a highly porous and sponge structure. It is easily quarried in block form and used as a building stone. However, it is important to plaster the surface to eliminate the pores.

Stone dust: This is the very fine dust, similar to sand, that is created as the stone is crushed. Stone dust is useful when tamping or packing stone, but it causes problems for applications where water needs to drain, such as behind a retaining wall.

Clean stone: If crushed stone is clean, it has been screened so the majority of the stone dust has been removed, but some dust is still mixed in. This is useful for the top layer of a stone driveway or other places where some minor compaction is not harmful.

Washed clean stone: This is stone that has been screened like clean stone, but then also washed to ensure there is no stone dust on the finished product. This is often used for drainage purposes, for ready mix concrete, or places that need aesthetic appeal, such as curbing or decorative stone.

Crushed stone: If you hear the generic crushed stone term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.

Or, if we were putting the base down for a patio, we want stone that compacts well and makes a strong base. Therefore, we want our stone to have stone dust, so we would call the quarry and order 2 crushed stone.

When putting down gravel in a flowerbed, make sure you start by laying down a quality landscape fabric, securely stake the fabric in place, and then layer the gravel on top of the fabric, usually 2-3 thick.

Stone dust compacts and hardens, especially when it becomes wet. Since drains need to always be open, it is important to keep stone dust out of drains. Therefore, construction projects needing drainage systems make sure they use only stone that has been cleaned and washed.

Crushed stone and gravel will continue to be a staple in construction, decoration, and industry for years to come. As recycling picks up, mining and quarries may slow down, but we will always need crushed stone in general construction and industry.

5 proven methods for keeping gravel in place on a slope | pepper's home & garden

5 proven methods for keeping gravel in place on a slope | pepper's home & garden

Keep gravel in place on a slope, hillside, or inclined driveway by installing a geotextile grid before laying gravel. Other techniques for preventing gravel from sliding are excavating and building an 810 inch deep bed of gravel, adding drainage trenches or culverts to prevent washouts, forming a ridge along your gravel roadway to help it shed water, and building a border alongside your driveway or path to keep gravel contained.

Most often, the cause of gravel slippage is improper installation. If the gravel was not laid to the proper depth, if drainage was not planned, or if an improper gravel type was used, it can account for material sliding downhill or becoming quickly destroyed by vehicle traffic.

Gravel installed on a slope with a grade greater than 15% (a decline of 15 feet over a distance of 100 feet) will likely not stay in place regardless of the methods used in construction. If your driveway exceeds this slope, you may want to consider rerouting your driveway to make a gentler path.

Always use angular gravel when laying a driveway or path, especially on a slope. These sharper stones lock together and resist sliding, while smooth gravelsuch as pea gravel and river rockslide easily.

Its essential to use different types of gravel to build up a proper base for a roadway or path. By laying large gravel first, then gradually transitioning to smaller sizes, you have a firmer roadway with better drainage.

There are several ways to improve the stability of gravel laid on a slope or hillside. Several of these methods can even be used together, to create a durable surface that resists erosion, ruts, flooding, and slippage. This will save you a lot of work regrading or raking gravel surfaces.

Installing a plastic or geotextile grid before pouring gravel is an excellent way to keep gravel in place on steeper slopes. The honeycomb structure of the grid forms several cups that capture the gravel and hold it in place. For additional stability, secure the grid to the soil using rebar stakes or a similar implement before adding gravel.

After the gravel grid is filled with #3 crushed stone, top it off with smaller gravel, such as #57 and #411 for a finer, more compact gravel path. This installation will stay in place even on steep slopes.

When laying gravel on an incline, its important to build it to a depth of 810 inches for driveways and roadways. This can be accomplished by excavating and grading the planned roadway with heavy machinery, or by laying gravel on top of existing material, with plans for installing a border once the gravel has been installed. To build a gravel surface that will stand up to vehicle traffic on a slope without slipping, do the following:

Its key to lay your gravel in layers, using a lawn roller to compact each layer. Moving from large gravel to smaller gravel is key to building a durable gravel base. This allows for proper drainage and compaction, which adds to the durability and resists flooding.

Washouts and flooding are a major cause of gravel sliding downhill or forming deep ruts. A dry gravel path or driveway is far more likely to remain in place. If you are planning a new gravel path, you can install concrete culverts beneath the gravel, to direct water under your gravel instead of over the top. For existing gravel paths and driveways, dig a trench drain alongside to keep them dry.

The good news is, since your gravel is installed on a hill, you have the perfect circumstances to dig drainage trenches that channel the water safely downhill before it ever pools on your gravel. This can make preventing washouts and flooding easier than it would be in flat areas.

When installing gravel, do not lay it in a flat, level layer from one side to the other. This causes water to pool and increases the chance of gravel sliding downhill. Instead, build your driveway or path so that there is a higher ridge in the center that slopes gently to the sides. This ridge or crown will shed rainwater and keep your gravel dry and in place.

A border of stones, pavers, or bricks can help contain gravel and keep it from sliding. Additionally, if you have built up a deep gravel base, this small wall will keep the gravel from spreading outward. Dont worry about the border serving as a trap for water. If you have built gravel from a base of varying sizes and installed drainage alongside your gravel, flooding wont be an issue.

In addition to physically keeping your gravel in place, borders can also be attractive features for your home. A properly marked and bordered driveway has a much neater look than a ragged gravel drive that peters off on either side.

Each of these methods will go a long way to maintaining a durable gravel path on a slope. By combining several of them, such as a gravel grid, drainage trenches, and a border, you can construct a gravel surface that holds up to the elements with little upkeep.

There are many types of landscape gravel you can use to enhance the appearance of your Albuquerque homes yard. The best gravel for your landscaping needs will vary based on the portion of yard the gravel will cover.

Landscape gravel is simply crushed stone that is used as a ground cover in landscape applications. Local landscape gravels are made up of either granite, limestone or quartzite and will last a lifetime, making it an economical choice for property owners who want a beautiful landscape without the maintenance or watering required with a lawn.

Crusher fines are typically minus and are ideal for walkways, driveways or even for a clean, minimalist ground cover look. They hold up well to foot traffic and because theyre so small, create a solid, flat surface that prevents slips and trips. True Crusher fines, like Amaretto brown and Blue Sais, are ideal for driveways, parking areas or walkways. These are fines created from the crushing of solid quartzite rock, creating six-sided fractured rock that locks together and creates a solid yet permeable surface. True Crusher fines do not contain any organic materials or clays, and naturally inhibit weed growth.

to 1 and 1 2 ground covers are consistently sized and are great for covering an entire landscape with gravel. They come in a nice variety of colors and materials. Larger sizes of gravel help to slow evaporation in the desert climate, reducing your water usage.

Larger sized gravel like 2 4 or 4 8 are ideal for sloped areas or drainage ravines where a large stone is needed to hold the shape of severe slopes, or to create a natural dry stream bed within your landscape design.

A xeriscape landscape is one that requires little to no irrigation. One to two-inch gravel is a great size for this type of yard as it helps retain moisture to the roots. One to four-inch rocks can be used to highlight feature areas of your xeriscape project.

River rock or La Paz Pebbles are often used around flower beds and in the bottom of planters to prevent the growth of weeds and improve drainage. Crushed rock may be used for driveways, and lava rock is an excellent alternative to mulch.
