Every street in Midvale is different, so all resurfacing projects are not exactly the same. As always, schedules are projected as accurately as possible but are subject to change due to the nature of maintenance construction and weather.

What is mill and overlay?

A mill and overlay consists of removing the top layer of pavement and replacing with new pavement. This process usually happens in 6 steps as follows:

  • Step 1: Repair or replace water and/or sewer lines
    • The City will repair or replace any deficiencies in City owned water and sewer lines.
  • Step 2: Adjust manhole rings and valve boxes
    • Lower manhole rings and valve boxes to allow for the milling of the road.
  • Step 3: Remove the old pavement (milling)
    • During this step, the top layer of pavement is ground off the road by a milling machine.
    • Generally, the street will remain open to traffic during the milling process, but a flagging crew may be directing traffic around the construction operations. The street surface is safe to drive on when the milling process is complete, but you will probably notice that the pavement surface is much rougher than before. Please drive with extra caution.
  • Step 4: Replace curbs and drainage inlets that need replacement
    • After the milling process is complete, crews will replace any curbs that have sunk over time and are collecting water and/or any drainage inlets that are damaged or disintegrating. Parking may be limited to allow for work crews to access the replacement sites.
  • Step 5: Replace the pavement (overlay)
    • Pave the new street surface. Before the new pavement is put down, a layer of glue (called "tack") is applied to the street surface to stick the new pavement to the old pavement.
    • The paving machine follows a few minutes behind the tack truck and lays down a fresh batch of pavement. Rollers follow closely behind to compact the new pavement to provide a solid surface to drive on.
    • You won't be able to drive on the new pavement until the crews are done rolling the pavement, and the pavement has dried. Flaggers will direct traffic.
  • Step 6: Adjust manhole rings and valve boxes
    • Adjust the manhole rings and valve boxes to ensure they are level with the new asphalt.

Why is Mill and Overlay important?

The major benefits of mill and overlay are to reduce surface roughness and address minor deformations, cracking, and irregularities in the pavement surface resulting in a much smoother ride quality. This type of resurfacing treatment prevents the City from having to perform a full street reconstruction, which can be costly and time-consuming.

How will I be notified if mill and overlay is scheduled on my street?

About one week before the resurfacing the project’s contractor will deliver a letter to residents that will be affected by the construction. Two to three days before the resurfacing the contractor will hang notifications on the doors of residents that will be affected by the construction. They will also post “No Parking” signs.

Approximately what time will crews be working on my street?

The crews work during daylight hours, generally between 7:00 a.m. and 7:00 p.m., on weekdays. Crews may also work on Saturdays, as needed.

Will my trash be picked up?

Most of milling and paving work is scheduled outside of routine trash pick-up days/schedule with no conflicts with the trash pick-up schedule.

Can I get in and out of my driveway while they are milling or paving?

Generally, you will be able to get in and out of your driveway except for the following times:

  • While the milling machine is going by your driveway
  • If there is curb being replaced in front of your driveway, you may not be able to access your driveway.
  • During the paving operation, you will not have access to your driveway from the time the paver goes by your driveway until the rollers are finished compacting the new pavement.

How is parking affected by mill and overlay projects?

Parking will be limited at times during a mill and overlay project so that the contractor can complete the work effectively. "No Parking" signs will be posted. When the parking restrictions are in effect, vehicles still parked in the construction area may be subjected to ticketing and/or towing.

Why do some cracks show up again soon after a mill and overlay?

Unfortunately, mill and overlay projects only address the surface of the pavement. If a pavement has cracks which extend down further than the top 1 to 2 inches of the pavement surface, those cracks tend to show up again after the new pavement is put down. These cracks are called "reflective" cracks and are common after mill and overlay projects. When these cracks appear, we will seal up the cracks so that they do not keep growing and ruin the new pavement.

 Some work may remain after the paving

This can include application of pavement markings, cleanup and replanting grass, if needed.

 Be safe around resurfacing projects

  • Slow down when driving through or near any road construction site.
  • Pay extra attention to pedestrians.
  • Be alert for construction workers and law enforcement officers.
  • The milled street before the new layer of asphalt is applied will have a rough surface. Drivers, cyclists and pedestrians should use caution.
