Aggregate crushing value test | Step by Step Procedure ...
It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for cement concrete road. The aggregate whose crushing value is less than 40% can be used for wearing surface.

Aggregate Crushing Value Test – Determine Aggregate ...
· 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 surface/layer.

Impact Test Of Aggregate | Lab Test Procedure ...
The road aggregates are subjected to subsequent impact due to the movement of vehicles. Hence, the road aggregates should possess sufficient toughness to withstand such an impact. The impact value test is hence used to determine the measure of the toughness of aggregates. 2. General Test Procedure of Impact Test of Aggregate The general test procedure of the aggregate impact value .

Crush samples having an impact value of % fall in the egory of 1020%, therefore, the aggregate test sample is classified as strong and can be seen in the table below. The aggregate impact value is useful for selecting the good aggregates for road construction. Aggregate appropriate for cement wearing course should have maximum AIV of 30%.

Aggregate Crushing Value Test
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with onethird of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.
