Of course we do but the testing companies are all private in our area. The DOT does have their own techs for some road work but the few DOT projects I've been involved in they allowed us to use a private company. This was just turn lanes and curb cuts.
Usual spec's for roads and parking lots are 95% density and 98% for building pads using a nuke gauge.
I have a small crew of 4 men with me being the 4th. My method of thinking is if I can pay for an attachment in a job that reduces labor, then it's a smart move. I wouldn't ask my operators to backfill a trench with jumping jacks and I don't want to deal with day labor..
As Scrub says "Different strokes".
What do you guys use for compaction in the streets and the like .
