Chapter 5, Problem 5.37QP
Calculate the fineness modulus of aggregate B in Problem 5.29. Is your answer within the typical range for fineness modulus? If not, why not? (Note that the percent passing the 1.18-mm [No. 16] sieve is not given and must be estimated.)
5.29 Table P5.29 shows the grain size distribution for two aggregates and the specification limits for an asphalt concrete. Determine the blend proportion required to meet the specification and the gradations of the blend. On a semilog gradation graph, plot the gradations of aggregate A, aggregate B, the selected blend, and the specification limits.
