Read MoreAggregate used in road construction should be strong enough to resist crushing under traffic wheel loads. If the aggregates are weak the stability of the pavement structure is likely to be adversely affected. The strength of coarse aggregates is assessed by aggregate crushing test.
Read MoreThe maximum aggregate crushing value permitted for bituminous macadam is. Q2. In how many layers aggregates are filled and compacted Q3. The aggregate is called high strength aggregate if the aggregate crushing value is high. Say True of False Q4. Number of blows given for each layer is Q5.

Read MoreJan 01 2019 The effect of the contact orientation distribution on the crushing of granular materials was studied by means of experimental and numerical tools. At first a simple dynamic experiment was presented to highlight the effect of the location of three contact edges on the fracture pattern and the strength of a model cylindrical grain.
Read MoreThe shape of an aggregate is very important in crushing tests. Dexter and Kroesbergen 13 emphasized that a major source of variation in crushing force was due to the variability in aggregate shape. In general researchers working on aggregate strength against crushing forces have assumed that the shape of aggregates is spherical 10.
Read MoreMay 21 2020 Therefore aggregate used for such propose should have sufficient toughness to resist their disintegration due to the impact. This important property of aggregate is determined by the aggregate impact value test. This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test.
