Construction Uses For Gravel and Stone

Posted by andy Mccoy on September 28th, 2021

Gravel and stone are part of a category of construction materials known as aggregates. Resin permeable agglomerates can be made from several materials, including not only gravel, stone, sand, crushed stone, recycled concrete, and slag. These aggregate materials are one of the basic, foundational elements of any construction project, and gravel and stone are a chief component in those materials.

So how are these important elements used in construction? And where might you use it best in your own projects?

Paving roads. Gravel and stone are part of the aggregate mix that forms the basis of paved roads all over the country. They are poured onto the road bed, then mixed with some kind of binding agent, such as asphalt, to keep the loose gravel and stone from sliding or shifting too much. These aggregate materials are hard enough to bear the weight of constantly passing vehicles, but also flexible enough to level out the inconsistencies between the ground beneath and the seal coating or smooth surface above.

Drainage. Because gravel and stones don't fit together perfectly, there is enough space between them to allow water to drain through them. This is why they're perfect for irrigation systems, drainage ditches, and roadside drainage to prevent standing water from become a hazard for travelers.

Residental driveways. The best way to construct a lasting gravel driveway or lane is to use two or three layers of aggregates. The lower layer, the one that lies on top of the dirt, is made up of larger stones. The middle layer is comprised of smaller stone and gravel, and the top layer uses gravel and dust to give a smooth feel and to seal in some of the gaps. With these three layers, the driveway has longevity, drainage, and comfort.

Railroad roadbeds. Since the beginning of rail travel, gravel and stone have been used to create railroad roadbeds, the gravel road that underlies the railroad tracks. These roadbeds are stable enough to support railroad ties and tracks, while permitting the drainage that keeps the rails from being submerged in water.

Water treatment plants. Gravel and stone are key elements in water treatment plants. Water is run over and through these materials again and again, each drain filtering out more and more of the hazardous materials.

Gravel and stone, some of nature's purest products, have many uses in the construction industry and in daily life. It's no wonder these natural resources are in such high demand.
