The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load. The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected.

Use our aggregate calculator to work out how much material your next landscaping project will require. Calculate the total volume, weight and cost. ... If you know the price per unit mass/volume of the crushed material, then the calculator can also work out the total cost of the aggregate using the formula:

A 20mm aggregate would need to be at least 4050mm deep, and at least 5060mm on driveways. A larger aggregate will settle and bond together better than smaller ones.
