Hi Guys,
Our company is based in Mass. We’re about to do a snowmelting (hydronic radiant) system under an asphalt driveway. We’ve done them in concrete applications before, but never in asphalt. I can’t seem to get a straight answer out of any radiant companies as to how the tubing and prep should be done. In other words, we would not be able to install the tubing into the asphalt itself and we can’t just lay the tubing in the gravel base-I think the asphalt spreader would crush it-not to mention the dump trucks. Is it advisable to put the tubing in a 4″ concrete slab first then pour the two layers of asphalt over that? Or is there an easier way to do this? If we did the concrete first, I’d assume that would act as the base for the asphalt. This is a pretty sizable driveway-approx. 4000 sq. ft.–ALOT of tubing. Thanks for advice in advance.

Put the tubing under a 6" bed of sand first and under pressure during the compaction.
