QueAfter two years of traffic, cores were recovered from the roadway which has severe ruttingand bleeding. The bulk specific gravity and the maximum theoretical specific gravity weremeasured on these cores and are as follows:Bulk specific gravity = 2.487Maximum theoretical specific gravity = 2.561a. Calculate the air voidsb. If the design air void content was 4%, explain what effect the calculated air voids hadon the rutting and bleeding noted.
