Aggregate Crushing Value Test -Determine Aggregate ...

05/05/2010  Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Standard of Crushing Value of Coarse Aggregates for ...

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 Crushing Value – Significance Test Procedure

The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.

01/02/2009  Natural coarse aggregates (crushed-stone) can be obtained from different type of rocks, mainly granite, calcareous, basalt and marble. Aggregates for concrete production, occupy 70–80% of its volume, where coarse aggregates are the larger part of about 2/3 of total volume of aggregates. The aggregates European industry (including concrete production, roads and railways) produces 3 billion ...
