Question:

The pavement repair project in Highway 101 in Ukiah is well under way, with several miles of new sections of concrete in the northbound slow lane. The patches are all various lengths from a few feet to a couple of hundred feet in length. When you drive over these patches, there is a noticable transition between the original concrete. The patches feel like they are a little higher than the original roadway. When there are several small patches in succession, it’s a bumpy ride. When the project is complete, is this what the surface will be like, or will something be done to even out the surface? Is this maybe a difference between a concrete roadway and an asphalt roadway? The repaired roadway is better than what was there, but the untouched fast lane has a smoother ride than the patched road. Thank you!

Answer:

Caltrans spokesman Phil Frisbie Jr.: The new sections of concrete will be somewhat rough until they are ground smooth. Since only the deteriorating sections are being replaced, there is a difference in height between the old and new slabs which will be ground smooth by the end of December, before the project is put into winter suspension.
