Electrical Density Gauge
Electrical Density Gauge
(OP)
Does anyone know anything about these things?
1) What is the history, how long have they been around?
2) Have you used them and what do you think?
Would love to get rid of the nuclear gauge. Is this an alternative?
Currently HMA compaction (QA) is done via cores. So it appears that we could do the remaining compaction tests (QA) with an EDG?

So I would really like to replace the Nuke gauge and get something that didn't require so much monitoring/certification. Especially since our lab is not used regularly enough (IMHO) to justify the nuke gauge.

I would also check with the controlling agencies on the road projects that you want to use it on (city/county/DOT). Sometimes you can run into those people that only allow exactly what is in their standards, because there is fear of the unknown.

Based on the responses, it doesn't sound like these are used much in practice (or I'm posting in the wrong forum?).
I will likely contact the state DOT, to see if they have an "expert" that will venture an opinion. I'm hesitant about going to the manufacturer for a reference, I certainly wouldn't expect to get an unbiased random reference from the manufacturer.
Engineers are becoming more like lawyers, never say anything unless pressed, then make it as vague as possible and apply numerous caveats. I like that we can post here anonymously--a better sampling method.

Unfortunately, my experience with "State Experts" has been that I have been told "If its not in the book, you can't use it."
Take a look at this link to the Transportation Research Board:

They have contacts for the Delaware DOT that are apparently studying this gauge as a suitable alternative. If you contact them, please clue us in on what they might have to say.
