Aggregate Base Course vs. Crushed Concrete Aggregate Base ...

These materials are ground to produce crushed aggregate, which is then mixed to make concrete. However, the supply of these naturally occurring elements is limited, and so recycled concrete can also be repurposed for use as aggregate. Crushed concrete aggregate base course is made from recycled concrete aggregate, which is created by grinding concrete that’s been reclaimed from demolished

The Effect of Aggregate Angularity on Base Course

stress levels, the resilient modulus of the natural aggregate mixture was higher than the 100% crushed aggregate. The trend reversed when the bulk stress was greater than 300 kPa. This suggests that, at lower depths in a thick (≥ 60 cm) base course layer, the lower half of the base course can be con-structed with natural material.
