Aggregate Impact Test For Road Aggregates Search Japan Mining Corporation

The impact test is a type of quality control test for highway pavements and is used to check the suitability of aggregates to be used in the construction of highway pavements. The property by which the aggregates are capable of resisting the impact is known as toughness.

test that an aggregate can undergo if it is to be used as a road surface course If an aggregate polishes too much under the polishing effect of vehicle tyres, the road surface becomes very slippery, especially when wet, and the number of skidding accidents can increase For the test, 10 mm chippings are placed.

These two aggregate samples were tested for sieve analysis test, relative density test, water absorption test, ten percent fine test, aggregate crushing value test (ACV), Aggregate impact value test (AIV), and Abrasion value test. Findings revealed that the best aggregate for road construction is the aggregate from Isi-Agu.

Roads are the backbone of our transport system, accounting for 90% of passenger journeys and almost 70% of freight. In the UK the highway asset is valued at over £800bn, making it our Government's most valuable asset. Our Government is committed to investing in this asset through Highways England and Local Authority budgets.
