 · 8. Recommended Crushing Value Standard of Coarse Aggregate in PA Mixture. In current Chinese technical specification, the crushing value of the coarse aggregate for surface layer of asphalt pavement is no greater than 26% . So, the crushing value standard of basalt coarse aggregate used in PA mixture should be increased to not more than 26%/1 .

Aggregate Crushing Value (ACV)Civil Engineering

Aggregate Crushing Value (ACV)Civil Engineering

Aggregate Crushing Value (ACV) The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous.

Crushing Value of Aggregate

Crushing Value of Aggregate

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 Crushing Load (Source: The Constructor, Civil Engineering Home)

Aggregate Crushing Value Test Of Aggregate

Aggregate Crushing Value Test Of Aggregate

With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.The Aggregate Crushing Value (ACV) Test Set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
