i agree with Chuck. the town road in front of my house is chipseal,
not asphalt. they are distinctly different and not hard to tell apart
once you know what to look for.

riding a bicycle on fresh asphalt can be quite nice. riding a bicycle on
fresh chipseal is literally riding on a layer of fresh gravel that's
been dumped on top of fresh sealer. i avoid it.
