From today's 5/13/13 Merc Roadshow
Q Several months ago, Caltrans repaved Skyline Boulevard. Before they repaved it, the road was in fine condition but the repaving job was so poorly done that the road is now terrible. In a number of spots, the new surface has already worn through, revealing the original pavement underneath and creating potholes. A good example can be found at Kings Mountain Road and Skyline.

A Don't expect a smoother road. Caltrans performed a chip seal job here, which is different from paving, and it says the work was fine and nothing more will likely be done. A chip seal can keep good pavement in good condition by sealing out water, but it provides no structural strength and repairs only minor cracks. It's a low-cost way to maintain a road, but it is not as smooth as paving, as Manny and others have found.
