5.1 Impact Value, as determined using the standard 4.5 kg (10 lbm) hammer, has direct application to design and construction of pavements and a general application to earthworks compaction control and evaluation of strength characteristics of a wide range of materials, such as soils, soil aggregates, stabilized soil and recreational turf. Impact Value is .The tested aggregate meets the requirements of the Malaysian Standard, which is 30% because it is less than 30% of the percent wear (average). b) Discuss three precautionary measures taken during the experiment. i. Both sides of the impact testing machine must be stepped on to facilitate the impact process on the aggregate. ii.
On the basis of impact loading tests and uniform loading test aggregate are classified on strength basis and are compared with standard limits. Of the selected aggregates, all the samples crushed in the range which is acceptable. Margalla Aggregate crushed the most under Impact loading and uniform loading while Sargodha aggregate crushed least.[19,20,21,22,23] Kwek and Awang (2018) [19] Water The aggregate impact value test determines the aggregate's resistance to sudden loading [24], which may differ from the resistance to .
