Howdy,
Going to be on a job next week testing compaction of a road-base made of fill which includes recycled asphalt. I'll be using one of the old Troxlers. I know I'm supposed to use an offset factor because the asphalt looks like water to the gauge due to the petroleum (hydrogen). I just can't find literature on what the specific numbers ought to be. Is there a rule of thumb way of correcting readings? Presumably, if a gravel was say 10% crushed asphalt it would need a smaller correction than if it were 70%. If I use a moisture offset does it automatically carry through for the dry density calculation?
