PEX in Asphalt

Unknown

I've often heard that "PEX and asphalt do not mix" since they are both petroleum products and the asphalt will break down and eat the PEX tubing over time. Anybody else heard of this?

I wonder if there is a specific type of PEX (A/B/orC) that may be better suited for asphalt pours? It appears that some tubing manufacturers have installation methods for this while others do not reccomend asphalt at all.

I'm a bit sceptical of a 2-3in. layer of sand or stone dust as it may act as an insulator.

Any thoughts?
