Twelve large-scale pavement sections were tested to determine whether engineered crushed stone can be successfully used to replace at least a por tion of asphalt concrete in the base course. A sum mary of the full-depth asphalt-concrete, crushed s tone-base, and inverted sections tested is given in Table 1.

However, when the standard is too low, the performance of asphalt pavement with the graded crushed stone layer cannot meet the actual mechanical requirements, which will cause pavement damage. Similarly, when the standard is too high, it is difficult to meet the requirements and practically apply in the practical project.

Using crushed recycled concrete helps keep construction costs down and minimizes waste dumped in landfills. Smaller pieces of crushed recycled concrete are commonly used as sub-base gravel or as a base layer for asphalt pavement. If it is free from contaminants, the crushed recycled concrete can be used to mix new concrete.

Crushed stone: If you hear the generic “crushed stone” term, it usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.
