Uses of recycled concrete. Smaller pieces of concrete are used as gravel for new construction projects. Sub-base gravel is laid down as the lowest layer in a road, with fresh concrete or asphalt poured over it. The US Federal Highway Administration may use techniques such as these to build new highways from the materials of old highways. Crushed recycled concrete can also be used as the dry ...

Earlier this summer, I wrote about different ways we could remove and repurpose some of the concrete around our home. Since then, we spent one full weekend jack-hammering part of our driveway and random paths around the house. The only problem – we now realize that we have way more concrete rubble than we could possible reuse!Concrete is inherently difficult to dispose of because it's ...
