Objective: 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory: The " aggregate crushing value " give a relative measure of the resistance of
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.
“Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load” In situations, when aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined and used instead.

The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS 2.1 An
number. Report the mean as the Aggregate Crushing Value, unless the individual results differ by more than 0.07 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the Aggregate Crushing Value. A data sheet is given as Form 7.7.1.
Aggregate Impact Values, (AIV’s), below 10 are regarded as strong, and AIV’s above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties. Aggregate Impact Value; Test Specifications:
Calculate the mean of the two values determined in (a) or (b) of 7.6.6.2 to the nearest whole number. Report the mean as the aggregate impact value, unless the individual results differ by more than 0.15 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest

Bullas and West [4] reported the aggregate impact value did not, but the aggregate crushing value did separate suitable and unsuitable aggregate for bitumen macadam roadbase. Fookes, Gourley and Ohikere [5] recommended that combinations of physical tests such as impact, crushing and abrasion resistance be used to assess aggregate

The test aims at looking for the forces required to produce 10% of fine values (i.e. weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.

The materials used in the preparation of laboratory-prepared Marshall specimens included four aggregate sources (denoted as A, B, C, and D) and one asphalt cement source (AC-20). Aggregates A, B, C, and D (all granite) had LA values of 55, 48, 30, and 28, respectively. The LA value was determined using aggregates of Grading B from each source.
