“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.
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:

DETERMINATION OF AGGREGATE CRUSHING VALUE. 1 To determine the aggregate crushing value of coarse aggregates 2 To assess suitability of aggregates for use in different types of road pavement 2 PRINCIPLE The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Crushing value is a
2.2.6 Aggregate Impact and Crushing Values Aggregate impact value gives relative measure of the resistance of an aggregate to sudden shock or impact and aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregates were tested in a surface dry 777
The findings indicated that water absorption of the coconut shell aggregate was high about 24 % but the crushing value and impact value was comparable to that of other lightweight aggregates.

Bullas and West  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  recommended that combinations of physical tests such as impact, crushing and abrasion resistance be used to assess aggregate durability.
Tests were conducted to determine the properties of plastic aggregate such as density, specific gravity and aggregate crushing value. As 100% replacement of natural coarse aggregate (NCA) with plastic coarse aggregate (PCA) is not feasible, partial replacement at

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.
Crushing is a size reduction process that plays a key role in both mineral processing and crushing-screening plant design. Investigations on rock crushability have become an important issue in mining operations and the manufacture of industrial crusher equipment. The main objective of this research is to quantify the crushability of hard rocks based on their mineralogical and mechanical
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 used in PA mixture, step-loading compression tests were conducted on the mixtures of PA-13 and a control asphalt mixture AC-13, respectively.
Apr 10, 2012· Calculations: Aggregate Crushing Value = (B/A) * 100 % * The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. * Aggregate crushing value < 45% for aggregates used for concrete for non wearing surfaces and <25% for wearing surfaces like runways and roadways.
The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads. Impact Value. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact. The impact value of an aggregate is sometime used as an alternative to its crushing value.
