The Pros and Cons of a Crushed Concrete DrivewayEcofriendliness is another big benefit of crushed concrete. Using this material helps slow down the production of new concrete and also frees up space in landfills. It prevents demolished concrete from sitting around taking up space and puts it to good use. Depending on how you have it installed, it's also rather permeable.
Use of Recycled Concrete Materials in Base/Subbase Appliions · –Approx. 1% to 2% passing the #200 from crushing clean concrete pavement –Additional fines come mainly from excavating underlying soils when loading the broken concrete –Gradation specifiions should consider: •Underlying material –subgrade vs. treated base •Modify specifiion as needed (reduce the low end of % passing the #200)
