Asphalt Compaction Issue
Asphalt Compaction Issue
(OP)
Can anyone tell me where I may find a written standard that allows for the adjustment of a marshall factor when nuclear testing the density of asphalt? My understanding is that the marshall factor may be adjusted to give a more accurate reading when testing a 1.5 inch lift of asphalt. I was told that the proctor of the gravel below needs to be accounted for. Any insight would be appreciated.

Most nuclear density gauges have a thin lift setting of some sort. It is best to contact the manufacturer of the gauge for instructions if you do not currently know how to set this up.
I hope this helps.

From my experience, this method can give fair result, but I would check the results by comparing the results agains 3 cores in at least 3 places to make sure that the correction is working properly.

Seems lately, there are a lot of labs breaking into the asphalt business because their concrete and steel work slowed down due to economic reasons. Problem is that not all realize how temperamental gauges can be, and they are causing problems. For example, taking the values off an uncalibrated gauge and reporting 93% of rice density when cores cores end up reporting 88% (yes...this happened).
Don't just take that gauge out and assume it is going to give you accurate results without assuring yourself it's check every few days against actual cores.
