Completing the Right Repair on the Right Road at the Right Time
When it comes to maintaining roads, Commerce City is committed to making the right repair on the right road at the right time. That’s why the city uses a comprehensive pavement maintenance and management plan that follows a sensible schedule for taking care of roadways.
Types of Street Maintenance
Criteria used to determine road repairs in the city include factors such as: pavement condition, traffic volume and roadway type. Once the roads are evaluated based on these factors, the appropriate type of maintenance is determined.
- Routine maintenance – cyclical, planned maintenance to extend the life of the road.
Examples: crack sealing, mastic asphalt sealing and pothole patching
- Preventive maintenance – applied to pavement in relatively good condition to extend pavement life and improve its appearance.
Examples: slurry seal, chip seal
- Corrective maintenance – a reactive method that extends roadway life through structural enhancements such as resurfacing and reconstruction.
Example: mill and overlay
Roads are typically rebuilt once they are completely deteriorated, which makes scheduled maintenance critical for extending the life of existing roads. Concrete pavement can receive routine maintenance, but since concrete is stronger than asphalt, it is more difficult to perform other types of maintenance and often requires full removal and installation of new material.
Routine Maintenance – Crack Seal
Crack sealing and mastic asphalt sealing are processes used to make minor roadway repairs that help extend the life of streets and prevent further pavement damage for a period of time.
Preventive Maintenance – Slurry Seal
Slurry seal, which is is a mixture of liquid asphalt and finely crushed gravel, is designed to extend the life of streets and improve their appearance.
Corrective Maintenance – Mill and Overlay
This process involves removing (or "milling") the top layer of pavement and replacing it with a new surface layer of fresh asphalt.
Concrete Pavement Rehabilitation
Repairing streets paved with concrete typically involves removing and replacing damaged or failing concrete panels.
