The Aggregate Crushing Value test (ACV) is based on a straightforward principle: aggregates are subjected to a controlled compressive load, and their resistance to crushing is measured as a percentage of the …

Discussion (LA Abrasion Test) Lab Report

It is important because the constituent aggregate must resist crushing, degradation and disintegration in order to produce a high quality. For this experiment, the LA Abrasion value obtained was 6 % and 9. %. based on the JKR Specification, the aggregate for use in bituminous road surfacing is maximum 40%. So, the value that was obtained is ...

Determination the Crushing Value of Aggregate test

The Crushing Value test measures the ability of an aggregate to resist crushing under a compressive load. It is a measure of the strength and toughness of the aggregate. In this test, a standard crushing load is applied to a prepared aggregate sample, and the percentage of fines generated after the specified amount of crushing is determined.

Aggregate Crushing Value Test

The values of aggregate crushing test agree in general with that of aggregate impact test. The crushing strength test is most significant as far as the conditions to which the aggregates is likely to be subjected in practice are concerned. The suitability of aggregate in the pavement layers is dependent upon the type of road construction.
