Reviewing asphalt test results | Asphalt magazine

Gmm is one of the most repeatable asphalt mix tests, with a multi-laboratory precision of 0.024, which equates to a difference in lab-molded density in the range of 1.0 percent. Gmb can be quite a bit more problematic to match from one lab to another, with a SGC maximum allowable difference of 1.7 percent.
