>>1617627This is such a fucking meme I don't know why governments keep falling for it. What a goddamn waste of money. Plenty of better places to put solar panels, like on the side of noise barriers.
>>1617624Not an issue if properly installed at 2% grade. The water will flow through and out to the side. We've got highly permeable asphalt (ZOAB) on all highways in the Netherlands for decades now and it works great. Bigger problem is keeping it clean. If a biofilm develops between the pores that greatly reduces the lifetime of the tarmac.
Obviously if the subsoil is not water penetrable you need some way of disposing the water to a ditch or berm.
>>1616945Asphalt is highly recyclable and has much lower CO2 emissions than concrete. Only if it's contaminated by tar you need to do heat treatment because tar is a carcinogen (outlawed as road building material in 1994 in the EU but it's still around).
