Dec 15, 2017· The aggregate impact value indicates a relative measure of the resistance of the aggregate to a sudden shock or impact which in some aggregates differs from its resistance to a slow compressive load. From the calculations done we know that the aggregate can be acceptable as their Aggregate Impact value is less then 20% Aggregate Impact Value 10.

Dec 08, 2017· Resistance to wear offered by aggregate is termed as "aggregate abrasion value". Los Angeles abrasion test on aggregates is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration.

"durability and soundness." The objective of this research is to select tests for characterizing aggregate toughness/abrasion resistance and durability/soundness that are related to the performance of asphalt concrete pavements. Toughness/Abrasion Resistance Aggregates must be tough and abrasion resistant to prevent crushing, degradation, and

The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load. The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected.

The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. Lower crushing value means higher strength, it's recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.

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:

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. It also revealed .
