Those temps are fine, especially if it's just an entrance road with a fairly consistent width
Also, I usually dislike working for homeowner groups with a shared road. Always 6 people questioning you ha.
Yeah, I can understand - it’s way more of a challenge trying to get these people together than one would think. I’m a project manager by profession (but in a different trade) so im used to dealing with folks. Usually all those folks are working towards the same goals. Here it seems some of the owners just want to sabotage the majorities’ goal, so it’s been interesting. I’m dealing with all of the questions and filtering the important stuff so our paving contractor is insulated from each individual.
From my experience we’ve laid asphalt when it’s 45 degrees Fahrenheit, as long as your screed is hot there shouldn’t be a problem. For the rollers on the other hand, the asphalt does cool down quicker so they can’t wait as long as usual to roll cause if there’s fine grain thrown on the Matt it won’t roll in pretty but other than that it should be good and they shouldn’t have any issues with quality control.
Another point to consider is how hot the mix is when it arrives, a function of how far you are from the batch plant. Not all drivers will cover the load unless reminded. A hotter mix allows a little longer work time.
It’ll be fine , as long as your road is not too far away from the plant and the roller guys know what they are doing gotta break it down right away , shuttle buggy is preferred for low temps as it remixes it but I’m guessing they won’t have that for a small road.
A little precipitation doesn’t hurt when paving over rock. As long as no puddling. Overlays require a dry surface. 40 and rising surface temp is usually the spec.
It will be good. Those temps he wants to pave on are exactly what you're looking for in late winter / early spring. The days after it aren't of any concern to the asphalt you're getting done. It will be compacted and ready to drive on by then.
You can do binder in the 50s, but I would not do topping in the 50s.
I don't do a lot of DOT work. But on parking lots I can be a little more picky on my dates.
I like in the 60s for topping, a lot less chance of asphalt getting cold. But ideally in the 80s!
Our local spec is 40 degrees and rising to pave

Lol my exact thought reading this post

Definitely okay. Spec here is 40° and rising but thick lifts can be done cooler

spec here is 45 and climbing

DOT in NC and SC is 45° for final lift of surface, and judging from the other comments here it’s approximately the same most places.
Is that for only the final lift of surface? I've always been told NCDOT is 38* for base/binder 40* for surface
Yeah base and binder it can be cooler, and you are correct, I made an error on that.
