Street Maintenance

Resurfacing – consists of replacing asphalt pavement that has deteriorated past the point of preservation

• The old pavement is removed from the street.
• The existing subgrade is examined and replaced as needed.
• Any curb and gutter that is deteriorated is replaced.
• Storm sewer and other utilities are examined and replaced as needed.
• New asphalt pavement is put in place.

Crack sealing – consists of sealing crack that develop in asphalt pavements.

• Cracks that go unfilled allow water to seep into the pavement structure.
• This moisture can freeze and thaw with changes in weather and cause the pavement to break apart.
• Crack sealing consists of cleaning out cracks with high pressure air and heat.
• These cracks are then filled with a rubberized tar that can expand and contract with changes in temperature.
• This has been found to be the most cost-effective form of pavement preservation.

Seal coating – consists of applying a slurry mixture to the street surface

• The asphalt slurry is able to fill in small ruts and cracks to keep moisture out.
• Streets need to be closed for several hours to allow the slurry to cure.
• The small stone aggregate that is mixed in the asphalt gives the street more skid resistance.
• The new street surface prolongs the life of the pavement.

 Asphalt repair – consists of patching or replacing distressed sections of street

• Some pavement repairs require a simple cold patch asphalt patch to fill potholes.
• Other repairs consist of removing sections of pavement and replacing them with new hot mix asphalt.
• We are also responsible for pavement replacement related to street openings for utility repairs.

Concrete Replacement Program – consists of routine replacement of concrete sidewalks and curb and gutter.

• Sidewalks are inspected yearly by district and distressed sidewalk slabs are marked for replacement.
• Our crews remove and replace these sidewalks throughout the summer.
• Curb and gutter that is distressed or settled is also marked and replaced.
• We also replace concrete that is related to street opening permits for utility work.
