Aggregate surface textures can increase the skid resistance of asphalt pavements, and large particle sizes can increase its ultimate load capacity. Sharp, angular aggregate textures can lend certain strength characteristics to concrete, or more rounded shapes can help it flow into confined spaces during placement.

Both coarse aggregates and fine aggregates are the main constituents of concrete because they not only give the body to the concrete, it also have a significant effect on the fresh concrete based on aggregate’s shape, size, texture, grading and crushing type. Moreover it is proved that aggregate’s types has the severe effect on physic-mechanical properties of concrete as

19-12-2019· The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low,

Procedure of Aggregate Crushing Value. Take a sample of aggregates by sieving through 12.5mm and retained on 10mm. The aggregate shall be tested in dry surface conditions. If dried by heating, the period of drying shall not exceed 4 hours and temp shall be 100-110 deg C.

Crushed stone is a derivative of crushing large stones - gravel, boulders of different rocks. The ratio of volume to mass of bulk material is the density of crushed stone in working condition. This parameter affects the strength of the stones, it is taken into account when preparing concrete mixtures and choosing a fraction to create embankments and litter.

Aggregate crushing value gives the Crushing strength of aggregate up to which it can bear the load without fail. To conduct crushing strength test we need compression testing machine, cylindrical measure, plunger and Isa sieves.
