Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled.

Impact Test Of Aggregate Lab Test Procedure

The procedure of the impact value test includes the following series of steps: 1. The aggregate samples of size 10mm to 12.5mm (passing through 12.5mm sieve and retained on 10mm sieve) are first taken and oven-dried at a temperature ranging from 100 degree Celsius to 110 degree Celsius for about four hours.

The Benefits of Commitment to a Currency Peg:

We develop a method to use the one-time cross-sectional impact of a cleanly identified shock to identify its aggregate impact through the use of a factor model. We apply this methodology to evaluate the importance of fluctuations to the commitment to a currency peg for macroeconomic outcomes during the gold standard period in the United States.
