Aggregate Crushing Value Aggregate Crushing Strength Test

As well as providing sufficient resistance to crushing under the roller, the aggregates should also resist crushing under the rigid tires of heavily loaded animal-drawn vehicles. A higher aggregate crushing value indicates more resistance to crushing under a compressive load. The ideal pavement aggregate will be one with a low aggregate crushing value.

Crushing Value of Aggregate - Welcome to Virtual Labs

The test conducted to know the compressive strength of aggregate is known as aggregates crushing value test. The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate. Aggregate ...
