Suppose you mean crushing and impact testing aggregate crushing test gives us the concept of aggregate strength and strength, and the progressive loading impact test gives us an idea of aggregate toughness.
The aggregate impact value test device consists of a testing machine weighing 45 to 60 kg, which has a metal base with a flat lower surface diameter of not less than 30 cm and supported by a flat concrete floor with a minimum thickness of 45 cm.
On August 26, 2020018332, the same sample is tested twice, and the average value is taken. The total weight of dry sample is wi GM, and the weight of crushed part passing 236mm is sieve is w2gm. Then the aggregate crushing value is defined as the ratio of the weight of fine aggregate passing the specified is sieve to the total weight of sample.
March 27 2020018332 aggregate impact test is considered to be an important test to understand the applicability of aggregate toughness in pavement construction. It has been found that for most aggregates, aggregate crushing and aggregate impact values are similar within strict limits.

The instruments used are cylindrical measuring tool and is screen of plunger compression testing machine, with dimensions of 125mm, 10mm and 236mm respectively. The procedure for determining the aggregate crushing value is that the aggregate passing the 125 mm sieve and retained on the 10 mm is sieve is dried at a temperature of 100 to 110 C for 3 to 4 hours.
The aggregate crushing value depends on the shape of the aggregate. The ACV of angular aggregate is lower than that of irregular or round aggregate. If we cut a core sample from the same aggregate in a quarry and conduct a compressive strength test, it can be considered as a concrete cylinder or UCS tested in the laboratory, so it is difficult to core.
