The table below lists data used in obtaining a mix design for an asphalt paving mixture. If the maximum specific gravity of the mixture is 2.41 and the bulk specific gravity is 2.35, determine the following below:
(a) the bulk specific gravity of aggregates in the mix
(b) the asphalt absorbed
(c) the effective asphalt content of the paving mixture
(d) the percent voids in the mineral aggregate VMA.
What will be an ideal response?
(a) Use Equation 18.5 to determine bulk specific gravity.
Gsb = (52.35 + 33.45 + 7.8) / [(52.35/2.51) + (33.45/2.74) + (7.8/2.69)]
Gsb = 2.6026
(b) Use Equation 18.9 to determine asphalt absorption.
(c) Use Equation 18.10 to determine effective asphalt content
(d) Use Equation 18.11 to determine VMA
