As similar thing happened to me along my main commute route. After a couple weeks, and a couple rain storms, the surface tar from the fresh asphalt was washed away and things are returning to normal. Kinda nice to be riding on a freshly paved road. What I do notice, especially at night is that the fresh asphalt doesn't reflect any light from my headlight making the ride home in the dark a bit dicier and somewhat surreal. Seems like I'm floating or riding through the cosmos or something.
