AGGREGATE IMPACT VALUE TEST-10+ IMPORTANT NOTES TO REMEMBER
It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact values are numerically similar within close limits. For deciding the suitability of soft aggregates in base course construction, aggregate impact test is commonly used. A modified impact test is also often carried out in the case of soft ...

Aggregate impact
Aggregate impact refers to the combined or cumulative effect of individual actions or events when assessed as a whole. In the context of legal analysis, particularly with the substantial effects test, it considers how seemingly minor activities can collectively influence interstate commerce, thereby justifying federal regulation. This principle emphasizes that while individual instances may be ...

Impact Value of Aggregate procedure, Limits
The impact value of aggregate measures how well a material can resist sudden, strong resistance, as aggregates with higher impact values are taken into consideration as much less durable and more liable to cracking beneath sudden masses, which may additionally affect the first-class of production. and Also, may affect sturdiness.
