16/07/2014 · Aggregate impact value test gives an indiion of aggregate's toughness property ( property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. Aggregate impact value (%) Toughness Properties <10 Exceptionally tough / Strong 10 – 20 Very tough / Strong [.]

04/09/2013 · This percentage is known as the aggregate impact value and more the aggregate impact value less is the toughness of the road aggregates and vice verse. If impact value is less than 10% then aggregate is said to be exceptionally strong, if it is in range of 10 to 20% then they are good, aggregates having impact value less than 35% are considered ...

Hence, they can be acceptable as their Aggregate Impact value is less than 30%. Aggregate ImpactValues, (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. If the aggregates are weak, the stability of the pavement structure is likely to be adversely affected.

The impact value is measured in the ratio between the sieved aggregate of 10mm aggregates. The aggregate impact value test will be conducted as per the Indian Standard Code IS code 2386 Part 4.

Based from the Aggregate Impact Standard, for the aggregate impact value of % which is in range 10% 20% is very strong for road surfacing. It shows that this aggregate is satisfactory in term of impact value of the road aggregates and it is suitability in road construction on the basis of impact value.

Explanation: According to IS: 2386 (Part IV) 1963 for the Aggregate Impact Value, the aggregates must pass through mm sieve and retain on 10 mm Start Learning Highway Engineering ≫ Highway Materials and Maintenance
