This summer, Roseville Public Works contractors will rebuild or repair more than 5 miles of city roads as part of the 2025 Pavement Management Project.
The work will be focused in multiple neighborhoods around Roseville including Pascal St, Iona Ave, Woodbridge St, and Farmington Ct. City crews will also be crack sealing up to 15 miles of roads.
This will include:
- 3.9 miles of mill and overlay work
- 1.2 miles of full pavement reclamation
- Crack sealing
What is Mill and Overlay?
Mill and overlay is a street maintenance technique where the top layer of a street is removed and replaced with a new layer of pavement.
The goal is to eliminate surface defects such as cracks, ruts, or uneven surfaces, and extend the life of the roadway.
The milling portion of the project typically takes one-to-two days. Before the new pavement is placed, the surface of the newly milled pavement is covered with a liquid asphalt tack coat to bond the old and new pavements.
Afterwards, a new asphalt overlay is placed at a depth of 1.5 to 2 inches.
What is full pavement rehabilitation or reclamation?
Pavement rehabilitation is a method that recycles 100% of existing materials on site. The full thickness of the existing asphalt and a portion of the underlying base are pulverized, mixed, and stabilized to create a new, strong base layer for a new road surface. It also takes less time compared to full reconstruction and is less expensive.
What is crack sealing?
Crack sealing is a common maintenance technique that uses a hot sealant to fill road cracks caused by temperature fluctuations, heavy loads, or aging materials.
Why are crews crack-sealing my road that was just repaired a year or two ago?
Crack sealing a new road might seem unnecessary at first, but it's actually a smart, proactive maintenance strategy. Sunlight, changing temperatures, and traffic loads create cracks even on newly milled roads.
Asphalt crack sealing prolongs the life of pavement by preventing water from infiltrating the road surface. Over time, water infiltration can lead to more severe issues, such as potholes. Crews use a router to open existing cracks to a width of about ¾ inch. The groove is blown clean and filled with the crack sealant.
