23-01-2018· APPLICATION S OF AGGREGATE IMPACT VALUE. Aggregate having AIV % less 50% is better to use in construction where as those having value more than 50% are bad for construction. It is reliable to calculate the AIV % of the aggregate use as road construction as it will give us the capacity of road to bear the load on it.

SOLUTION. Aggregate impact value test gives an indication of aggregate's toughness property (i.e. property of a material to resist impact).. Aggregates to be used for wearing course, the impact value shouldn't exceed 30 per cent.. For bituminous macadam, the maximum permissible value is 35 per cent. For Water bound macadam base courses the maximum permissible value defined by IRC is 40 per ...
12-09-2015· Aggregate impact value = (W1/W2)*100. Aggregates to be used for wearing course, the impact value shouldn't exceed 30 percent.

The percentage mass of fines (passing a 2.80mm BS test sieve) formed in the test is known as the aggregate impact value AIV. higher values are given by weaker materials. For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values which are about 5 units higher than their crushing values.
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.
Aggregate Impact Value For Construction. Jan 12, 2017nbsp018332The aggregate impact value is a calculation of the resistance to abrupt impact, bang or shock, which may vary from its resistance to steadily, applied compressive weight.
Recommended aggregate impact value Precaution for aggregate impact value test. The sample of aggregate should be sieved in circular motion or movement. The sample aggregate should not be overheated on the oven. The weight of samples and dust should be tamped with the help of a standard size tamping rod.
21-05-2020· Aggregate impact value is the ratio of the weight of the fraction passing through 2.36 mm (weight W2) by the total weight of the sample (weight W1 + W2). Aggregate Impact Value = (W2/ (W1+W2)) * 100 = 80 gm / 300 gm = 26.67 (Impact …
