Recycled concrete aggregate (RCA) is most commonly used in compaction and is suitable for the first layer of building as it is perfect for wet or soft ground, a better alternative for “fill,” and an ideal, low cost material for driveways, parking areas, walking paths, etc. 
Recycled concrete aggregate (RCA) is widely considered to be a more cost-effective material than stone or regular concrete. This is because it does not have to be mined and can be produced relatively easily.
A maximum of 5 cubic yards of RCA can be delivered at a time.
