Table below shows the sieve analysis test result for aggregates A and B and the specification limits for an asphalt concrete. Determine the blend proportion required to meet the specification and the graduations of the blend. On a semi-log gradation graph, plot the gradations of aggregate A, aggregate B, the selected blend, and the specification limits in a same graph (you can use Excel sheets or you can draw the graphs on a semi-log attached to page 3 of this assignment). 1912.59.54.752.360.600.300.15Specification limit10080-10070-9050-7035-5018-2913-238-16Aggregate A100904535121030Aggregate B1001001008077453218 Percentage passing % 0.001 0.01 0.1 1 10 100Sieve Size (mm)

Table below shows the sieve analysis test result for aggregates A and B and the specification limits for an asphalt concrete. Determine the blend proportion required to meet the specification and the graduations of the blend. On a semi-log gradation graph, plot the gradations of aggregate A, aggregate B, the selected blend, and the specification limits in a same graph (you can use Excel sheets or you can draw the graphs on a semi-log attached to page 3 of this assignment).
