Comment on Costco changed the bag to plastic!!

Plastics aren’t often used as a building material because of toxic off-gassing, but of course this would be outside which would mitigate the issue.
Asphalt is one of the most recyclable materials in existence, when they tear up an asphalt road they just melt it down and pour it back on. If there was plastic involved it would probably interrupt this process.
But I’m not expert. Maybe it would work.

Literally asphalt is junk plastic/petroleum. It dissolves or mixes with plastic at melting temp. Or even if there was no thermal action, the plastic in fiber form would just get incorporated into the melt.

although there are ongoing experiments for this, results aren’t promising.
standard road asphalt contains recycled tires for their elasticity and longevity. there have been cases where plastics have been used in the formation of walking/bike paths, but recent investigations have discovered an inordinate amount of microplastics have found their way into watersheds in the vicinity of these paths.
sometimes a bad product is a bad product. due to the hubris of oil companies they continue to market and sell these products as “recyclable” when in reality the process of recycling them is a costly and complicated solution that has been proven within the confines of a lab test.
it took the US 70 years to identify and stop using lead based paints in home construction. it was replaced with…you guessed it, oil based paints that contain plastics. we’re currently running up to 60 years on that. I wonder what the next big thing will be?

You should check out asphalt. When it rains you can see a slick of oil coming off of it. Its literally tar.
