Utility companies and City agencies are consulted. Do they have some work planned that would conflict with CDOT street maintenance and resurfacing work? For instance, should water or electric lines need repairing or installing, it might be best to delay resurfacing until the needed utility work is done. During paving season (April to November), there is continuous communication to attempt to avoid conflicts. Once the maintenance process begins, it may look like work has been started and left unattended for a time but in reality, it’s just in line to receive the next scheduled step or process. Weather and other factors can play a big part in how quickly the resurfacing work can be completed. Thus delays are to be expected.
Each street is divided into segments, usually from intersection to intersection. Sometimes only portions of a street need work and occasionally it may appear to citizens that the street looks just fine the way it is. However, often it’s what’s not visible to the motorist and underneath the surface that is about to cause problems that requires attention. Depending on the extent of resurfacing, many processes may be required over some weeks or months.
These processes can include:
Asphalt Base Repair - An asphalt repair patch crew digs out the cracked and broken asphalt base failure, then patches back, often times by hand. The patches can look and ride rough compared to the undisturbed pavement, especially if the patches cover a large area. These patches are necessary to rebuild the asphalt foundation to support the new asphalt resurfacing layer.
Concrete Work - After the asphalt repair crew finishes the asphalt repair, the concrete repair crews will arrive to repair any damaged or broken curb and gutter, and install handicap ramps if needed.
Milling & Structure Adjustment - If the street needs milling, existing pavement will be ground down to make room for the resurfacing asphalt overlay (usually 1 inch of asphalt). If the street doesn’t need milling, work crews will come prior to resurfacing to raise the manholes to be flush with the new asphalt resurfacing overlay. When manholes are adjusted, the resurfacing crews are usually within 2 to 3 weeks from resurfacing the street. (Signs are posted on the street stipulating property owners and traveling public the street is to be resurfaced)
On Street Parked Car Notification – About 48 hours before resurfacing, notices are placed on car windshields parked on the street announcing the upcoming street work and that owners should move their cars from the street. If a car is not moved from the street when the crews arrive to resurface the street, attempts will be made to contact the owner. As a last resort, the car will be towed from the street until the resurfacing is completed. Then the car will be towed back to the location where it was parked after the street parking area is resurfaced. If this action is necessary, there is no cost to the car owner. The towing fee is paid by the City.
Asphalt Surface Treatment and Asphalt Resurfacing - If the street was milled or the pavement has excessive cracking, a bituminous surface treatment (tar and gravel) is applied, then immediately paved over by the resurfacing crews. This treatment retards previous cracking from the old asphalt street migrating up to the new asphalt surface.
Pavement Markings - Pavement markings such as centerline, stop bars, and lane markings will be reapplied within 3 days of the resurfacing. Temporary markings may be applied for safety reasons, and the permanent markings may be applied at a later date. Sometimes bike lanes will be installed.
