  • Aggregate Crushing Value Test Determine Aggregate ...

    Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.

    A crushing strength of 4,000 lb means that a cubic inch of the rock withstands pressure to 4,000 lb (111 kg/cm 3) before crushing. The crushing strength is greater with shorter prisms and less with longer prisms. Ref: Fay ii. The pressure or load at which a material fails in compression; used for comparing the strength of walling and lining materials, such as concrete, masonry, stone, packs, etc. Ref: Nelson iii.
