Given: The average sublot density (Gmb) of the roadway cores is 2.223 and the Gmm
for the same sublot is 2.400. The target spread rate was 162 lbs/sq yds. What is the %
of Gmm density for the sublot? - ANSWER 92.6%

on the same ore Gmb test is equal to 2.205, do these two values compare? - ANSWER
Yes
If roadway density values are decreasing throughout the shift, the possible cause could
be:
A. Not enough trucks on the project
B. Plant production rate cant keep up
