Problem #1 A core is removed from a pavement designed with 6% asphalt binder. The mass of the core is 1238.5 g in air and 698.3 g submerged. The maximum specific gravity of the mixture is 2.48, and the bulk specific gravity of the combined aggregate in the mixture is 2.64. What is the percent voids in the mineral aggregate (VMA) of the core?
The VMA of a mixture is 16.0 % and the air voids are 4.0 %. If the aggregate has a specific gravity of 2.7, estimate the asphalt content by weight (assuming no absorption and specific gravity of asphalt 1.000).
Problem-6 An asphalt concrete mixture is to be designed according to the Marshall procedure. A PG 64-22 asphalt cement specific gravity of 1.00 is to be used.
