An asphalt concrete specimen has the following properties:Asphalt content = 5.5% by total weight of mixBulk specific gravity of the mix = 2.475Theoretical maximum specific gravity = 2.563Bulk specific gravity of aggregate = 2.689 Ignoring absorption, calculate the percents VTM, VMA, and VFA.
Binder grade of asphalt selected for a highway construction based on the temperature recordsfound to be PG70-16. Answer to the following questions:• If traffic speed is high (more than 70 km/h) and 0.2 million ESAL, what is your suggestionfor the binder grade?• If traffic speed is slow (less than 20km/h) and traffic volume is very high (40 million EASL), what is your suggestion for the binder grade?
The mix design for an asphalt concrete mixture requires 2 to 6% minus No.200. The three aggregates shown in Table are available.Considering that approximately equal amounts of coarse and intermediateaggregate will be used in the mix, what is the percentage of fine aggregate that will give a resulting minus No. 200 in the mixture in the middle of the range,about 4%?

Given below are the requirements of a specification related to the grading of mineral aggregates in an asphaltic concrete mixture and sieve analysis of two aggregates (A and B) that are economically available for this use. Determine the range of blends of aggregates A and B that will produce a combined aggregate that will meet the limits of the specification, and given the grading of the aggregate combinations selected.
I have the correct answer but don't know how to solve it. Wrong solution will be downvoted. A 5% of Rediset is used by the weight of asphalt binder to produce a WAM specimen has 1080 gm aggregates and 60 gm filler.
