I don't think permeable asphalt would make much of a difference. The surface area of the trail is small compared with roads around, and you can see the ground itself is saturated, that's why water is pooling even on the ground. It's not that the asphalt trail is forming a bowl, we simply need proper drainage.
Using permeable paving on the roads or sidewalks could make a big difference, but it's pretty expensive.
