The crushing resistance of lightweight aggregate apparatus is used to determine the crushing resistance of lightweight aggregates. It comprises a steel cylinder and piston. Two versions are available: Procedure 1: apparatus with cylinder int. dia. 113 mm Procedure 2: apparatus with cylinder int. dia. 76 mm
In addition to material strength (Xuan et al., 2015;Li et al., 2017), the crushing characteristics of the aggregates are essential to ensure road stability.
The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.

The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be preferred. Why to test Aggregate Crushing Value? The principal mechanical properties required in road stones are:

On Special Request Aggregate Crushing Value Apparatus having 75mm dia or 300mm dia cylinder size can be supplied. Aggregate Impact Tester Make: LabTek Model: SL-AG-002 Origin: India Standards: IS 2386 (PART IV) 9377 & BS 812:112 Specification: It is robustly designed to determine the aggregate impact value (AIV) of aggregates
The purpose of conducting this test is to determine the aggregate crushing value of coarse aggregates and evaluate their suitability for use in various types of roads. Apparatus. Apparatus needed for the aggregate crushing value test includes a steel cylinder with a diameter of 15 cm, along with a plunger and base plate.
Report the mean as the aggregate crushing value, unless the individual results differ by more than 0.07 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number, and report the median as the aggregate crushing value.
