Found out the finisher on the I-35 job poured 900 feet of curb without a single cold joint, and I'm still chewing on it
He runs two crews and claims the trick is mixing a half bag hotter on the last 20 feet so it sets with the pour ahead of it. I've been fighting cold joints on curb for years and never thought to change the mix at the tail end. Any of you guys mess with your mix at the end of a run like that, or is he just lucky?

Hotter tail mix works if the truck timing is tight, but cold weather will bite you.
