· 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 Value) Where, W1= Weight of the fraction passing through 2.36 mm IS sieve.(220 gm)

Aggregating impacts adds up the total impact of climate change across sectors and/or regions (IPCC, 2007a:76) producing aggregate impacts, there are a number of difficulties, such as predicting the ability of societies to adapt climate change, and estimating how future economic and social development will progress (Smith et al., 2001:941). It is also necessary for the researcher to make ...

· The apparatus of the aggregate impact value test consists of: A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. Level and plane concrete floor of minimum 45 cm thickness are used to support it. The base of the machine should also have provisions for fixing its base.

The aggregate impact values are strong (on the average, by about 10% to 30%) than 8 the aggregate crushing values. Various agencies have specified the maximum permissible aggregate impact values for the different types of pavements, those recommended by the roads for deciding the suitability of soft aggregates in base course construction, this ...
