Yep, me too. I haven't noticed that effect at all......except where the big machine has scrapped off the top layer in prep. for new asphalt. Guess the California road builders are more afraid of rain than they are elsewhere! :biggrin:
I would think that the effect would be less noticeable in the tire tracks.......where the grooves should be flattened out some ????
