Street Reconstruction is the most extensive type of project. Crews remove the pavement, the base below it, and sometimes the curb, then construct a new roadway.
Street Rehabilitation removes and replaces the curb, then resurfaces the entire pavement surface.
Street Resurfacing involves grinding the existing pavement in order to put down a new top layer of pavement.
Road maintenance includes less extensive construction, such as patching, some pavement resurfacing, and correcting potholes and surface defects.
