· Aggregates with lower crushing value show a lower crushed fraction under load and would give a longer service life to the road and hence a more economical performance. If we used a weaker would get crushed under traffic loads, would produce smaller pieces not coated with a binder, and these would be easily displaced or loosened out resulting in loss of the surface/layer.
Aggregate Crushing Value Test
The crushed aggregate sample which is finer than mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the "ten percent fines value" should be determined ...
