DETERMINATION OF AGGREGATE CRUSHING VALUE

1 To determine the aggregate crushing value of coarse aggregates 2 To assess suitability of aggregates for use in different types of road pavement 2. PRINCIPLE The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a

Aggregate crushing value 100W2WI Aggregate Crushing

When traffic moves on the road the soil particle sand which comes between the wheel and road surface causes abrasion on the road stone. The abrasion test on aggregate is found as per I.S.-2386 part-IV. Abrasion tests on aggregates are generally carried out by anyone of the following methods-1. Los Angeles abrasion test. 2. Deval abrasion test. 3.

AGGREGATE IMPACT VALUE TEST10 IMPORTANT

Jul 16, 2014 Aggregate impact value test gives an indication of aggregates toughness property i.e. 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

Aggregate Impact Value Test Procedure Result amp Standards

May 21, 2020 Therefore, aggregate used for such propose should have sufficient toughness to resist their disintegration due to the impact. This important property of aggregate is determined by the aggregate impact value test. This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test.

Aggregate Crushing Value Test Significance amp Test

Significance of Aggregate Crushing Value Test. The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously.

Aggregate Crushing Value Test Determine Aggregate

May 17, 2019 Aggregates with lower crushing value show a lower crushed fraction under load and would give a longer service life to the road and hence a more economical performance. If we used a weaker would get crushed under traffic loads, would produce smaller pieces not coated with a binder, and these would be easily displaced or loosened out resulting in loss of the surfacelayer.
