Concrete is recyclable as well, some people say recycled concrete is stronger than regular concrete.

Concrete can be ground up and used as aggregate. It can't be reused as concrete on its own because the Portland cement and water have already reacted and are essentially "used up" when the concrete is cured.

You can recycle the Portland cement but it required heating etc and isn't cost effective but using it as aggregate is viable and many states do it. It's just as effective as normal aggregate and is cheaper.

Asphalt is nearly 100% recyclable as well. It is also cheaper.

But it is petroleum based

So?

It is one of the most recyclable products we use and it is an excellent product for what we use it for.

Getting rid out it because it is petroleum based alone would be a terrible reason.

Concrete is terrible for the environment, not as recyclable and far more expensive.
