5.29 Table P5.29 shows the grain size distribution for two aggregates and the specifi- cation limits for an asphalt concrete. Determine the blend proportion required to meet the specification and the gradations of the blend. On a semilog grada- tion graph, plot the gradations of aggregate A, aggregate B, the selected blend, and the specification limits.
