A base repair project completed by PBOT crews on N Princeton Avenue, adjacent to Astor Elementary School. The road had a 20-foot travel lane with two 8-foot wide gravel shoulders and a non-existent curb line. Crews excavated the failing, pothole-riddled road, repaired the road base, exposed the curb line, and paved it curb to curb.

Base repair projects are reserved for streets that are in poor or very poor condition. They address those portions of the street that have failed from top to bottom. The goal of these base repair projects is to prevent the structural failure from spreading to other parts of the street. Because base repair projects replace both the asphalt and the street’s rock base, they are more expensive than other preventive maintenance projects. For this reason, they also tend to be smaller, ranging in size from of tabletop to city block.

The projects shown on the Fixing Our Streets interactive map are subject to change as PBOT crews assess the structural causes of each failure and make sure that the repair will improve the pavement condition.
