1. It is desired to plot the band of gradations allowable specified by ASTM in the semi-logarithmic plot of the enclosed sketch. Then it is desired to calculate the gradation for the sand from the candidate borrow pit area. 2. It is desired to plot the gradation curve for the sand from the candidate site in the same graph with the gradation requirements of ASTM, and assess whether the sand from the candidate borrow pit area is acceptable.
