Questions 30 is based on the information below:
An asphalt concrete mix design has the following properties. The densities of the binder and aggregate
are 1.090 g/cm³ and 2.760 g/cm³, respectively. The bulk density of the entire mix is 2.220 g/cm³.
The percent binder content is 6.2% (by weight). Assume no absorption.

30. As an engineer, you are asked to use this mix design for a 25 kilometer-long section of roadway where
the total pavement width is 8.0 meters and the thickness is 15 centimeters. What is the (a) total volume
of binder and (b) the total volume of aggregate that you would need to purchase? Also, determine the
(c) total %air voids in the mix.
Use the following volumetric relationships for asphalt mix analysis:
VTM = 100 (1 - Gmb)
VFA = 100
3. An asphalt concrete specimen has the following properties:
Asphalt content = 5.5 % by total weigh of mix
Bulk specific gravity of the mix = 2.475
Theoretical maximum specific gravity = 2.563
Bulk specific gravity of aggregate = 2.689
Assuming there is no absorption of binder, calculate the following:
