Given the particle size distributions of three aggregates and the required limits of particle size distribution for the mix (Table 1), determine a suitable ratio for blending the three aggregates to obtain an acceptable combined aggregate. Also, please solve the specific gravity of your blended aggregates, given specific gravities for stockpile A, B and C are 2.58, 2.65 and 2.55 respectively.
