Public Works: Pavement Maintenance

Public Works performs asphalt repairs when pavement sections begin to fail due to pot holes, cracking, pumping or settling as a result of a poor sub-base and/or pavement conditions. The freeze-thaw cycle in northern Illinois takes a toll on the condition of our roadways.

If the road base is sound, the surface layer can be removed and new material installed. In more severe cases with poor base conditions, the surface and binder courses may need to be removed, cored out and a new gravel base installed before the asphalt can be laid. All layers of the repair process must be compacted, rolled into place and given sufficient time to cool before the road is open for safe travel.
