Coarse aggregate crushing value is the percentage by weight of the crushed material under standardised load and condition. The crushing value indicates the strength of aggregates. The aggregates used for quality pavement should be strong enough to withstand the crushing under roller and traffic loads i.e. Low crushing value.
The Aggregates which will get retained on the 4.75 mm (No. 4) sieve and will pass through a 3-inch sieve are known as Coarse aggregate. The aggregates used in the production of concrete are inert granular materials such as gravel, crushed stone, sand, slag, and recycled concrete. The aggregates might be natural, manufactured, or recycled.
· 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. ...

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. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.
AGGREGATE CRUSHING VALUE (IS:2386. May 08, 2013· Objective For determination of the aggregate crushing value of coarse aggregate, which passes 125 mm IS sieve and retained on 10 mm IS sieve Reference Standard IS: 2386 (Part IV)-1963 Methods of test for aggregate for concrete Part IV Mechanical Properti Equipment & Apparatus Steel Cylinder Sieves …
Aggregate Impact Value, Aggregate Crushing Value, Compressive strength were lowered with an increase in recycle aggregate content. The recycled coarse aggregates (RCA) had little influence on the hardened density of concrete and an increase in recycled aggregate content led to a decrease in capacity.
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 …
different crushing of aggregates same cement and quality of water was used. Fine aggregate (sand), impact crushed coarse aggregate (A-1) and vertically shafted coarse aggregate (A-2) properties were evaluated through lab testing. Source of aggregates, density and porosity (water absorption) of A1 and A2 coarse aggregates were kept constant.
Aggregate crushing value test theory 15m3h240m3h ggregate 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.
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 …
Crushing Test of Aggregate The aggregate crushing value test shows the strength of aggregate which is one of the most important properties of coarse aggregate. The aggregate crushing value gives a related action of resistance to crushing under a gradually applied compressive load.
Fig. 10 shows the Zingg's shape classification of coarse aggregates of size P20-R16 mm, P16-R12.5 mm, P12.5-R10 mm and P10-R6.3 mm produced from J-C and J-J crushers. It is observed that for all aggregate sizes, J-J crusher had higher number of particles distributed in disc and blade range compared to J-C crusher.
