Aggregates. Aggregates are the fraction of rock which are inert or non-reactive. These are obtained from rocks by means of crushing. Main constituents of the wearing surface are bitumen and aggregates. Mostly 90 % of the road consists of aggregates. There are two problems to use non-inert materials.

Aggregate crushing value (acv)-testing procedure
Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, step-loading compression tests were conducted on the mixtures of PA-13 and a control asphalt mixture AC-13, respectively.

Aggregate definition. Aggregates are the major ingredients of concrete. Aggregates are derived from rocks. They are broadly divided into two categories i.e. fine aggregate and coarse aggregate. Their properties are depended on the mineralogical composition of the rock. Crushed rocks are used as coarse aggregates are river sand is used as fine

AGGREGATE CRUSHING VALUE 1.Objective The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. 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 percentage mass of fines (passing a 2.80mm BS test sieve) formed in the test is known as the aggregate impact value AIV. higher values are given by weaker materials. For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values which are about 5 units higher than their crushing values.
