Crushed Concrete Vs Traditional Gravel

In the past, when structures were renovated or destroyed, the materials were disposed of in landfills. This took up large amounts of space in landfills, wasting resources, and wasting money in transportation. Recently, recycling the materials has grown more popular as an alternative to disposing of it.

Typically, concrete gathered from demolitions or renovations is sent through a machine that crushes it to a gravel-like consistency. This can be used for many applications such as driveways, walkways, gardens, and much more. It also has a series of advantages over more traditional materials.

Price

Crushed limestone is a typical rock used to make gravel for driveways and walkways. Depending on the size and the source, the rocks are sold by the ton, the bag, or the cubic yard of coverage. Typical costs for this material are $20 to $40 per ton, $3.00 to $7.00 per 50-pound bag, or about $45 per cubic yard.

To compare, recycled concrete is sold in the same ways. It sells for $6 to $14 per ton and $20 to $30 per cubic yard. A driveway which is 30 feet by 20 feet requires almost six tons of gravel to cover two inches deep. That means if you were to pave that driveway with limestone gravel, you could spend as much as $240. If you are building on soft ground, you will need more than just one layer of gravel. The prices could easily double or triple in that case.

However, using crushed concrete could cost as little as $36 to pave a 20 foot by 30 foot driveway. That is almost 700% cheaper than traditional materials.

Environmental Impact

The use of a recycled material instead of new gravel reduces the need for gravel mining. This means that fewer machines burn fossil fuels to dig rock quarries and less ground is disrupted for new gravel.

Also, the use of recycled aggregate means that less water is used to make cement for driveways, walkways, and such. Less cement being produced means that the waste byproduct will not go to a landfill and occupy more space.

In contrast, a traditional material such as limestone requires heavy machinery mining to be extracted from the ground. This process typically kills trees and other plants in the area of the mine. Also, any animals in the area tend to run away from the mines due to the dwindling habitat and the bustle of the construction. The material then has to be shipped from the quarry site to the construction site.

Availability

While certain minerals and rocks need to be shipped from areas where they are common, concrete is common just about everywhere there are buildings. This means that you should be able to find the material quickly and easily wherever you are. Whichever supplier you choose should be a local one. This is because prices for materials are typically estimated with the assumption that the buyer will pick up the load. Companies typically charge extra to ship it themselves and these costs increase the farther it has to be shipped.
