Another common test is the crushing strength test. This test measures how much force is needed to crush a given sample of aggregate. This can help to determine how strong the aggregate will be when used in a construction project. Tests on aggregates are. Tests on aggregates are an important part of the quality control process for asphalt pavements.

· You place several pounds of the sand, gravel or stone in a Pyrex dish of convenient size, such as 9 x 13 inches. Weigh the filled dish, then deduct the weight of the dish. Place the dish in the oven for about 30 to 40 minutes at full power setting. Using oven mitts, remove the dish, cool it to room temperature (about 45 minutes) and weigh.
· Construction aggregates derived from primary resources either by crushing of sound rock masses (crushed stone aggregates) or from naturally occurring unbound clastic sediments (natural sand and gravel aggregates) make the most voluminous mineral raw material exploited by humans nowadays (Fookes 1991; Přikryl 2017 ).
