Crack Sealing in Seattle

For interpreter services, please call

Overview

What is crack sealing?

Crack sealing is a commonly used preventive maintenance activity for pavement. Crack sealing prevents infiltration of water and other materials. This extends the life of the pavement. 

When water seeps through cracks in the pavement it can freeze, expand and damage the pavement. 

Crack sealing helps reduce structural deterioration, minimize pothole formation, and can prevent pavement distresses.  It helps maintain streets in good condition, postponing the day we need to repave or rebuild them.

Background

Crack sealing typically happens in the summer to mid-September when conditions are relatively dry and there is little chance of rain.  The crack seal process for a particular block is typically done within a day.

The roads that are selected for this preventive maintenance are rated as relatively in good condition (with surface cracks but no structural deterioration), based on SDOT’s latest pavement condition assessment of Seattle’s arterial streets, using the pavement condition index (PCI) rating for the streets.

 

2014 Project


Typical cracks filled by crack sealing

SDOT’s 2014 Crack Seal Program plans to fill over 80,000 linear feet (LF) of pavement cracks. If you lined up all these cracks end to end, they would stretch over 15 miles.  That’s about as far as the northern border of Seattle at Shoreline all the way south to the South Park Bridge.

Locations of 2014 Crack Seal Program

The 2014 program will begin the first full week of August, starting at S McClellan St, and continuing through the list of streets here:

  • S McClellan St between M L King Jr Way S and Mt Baker Blvd S
  • S Jackson St between Rainier Ave S and 31st Ave S
  • E Yesler Way between 14th Ave E and M L King Jr Way
  • E Jefferson St between Broadway and 23rd Ave
  • S Columbian Way between Beacon Ave S and 15th Ave S
  • 15th  Ave S between S Columbian Way and S Spokane St

If budget allows:

  • Rainier Ave S, between 57 Ave S and S Othello St
  • Rainier Ave S, between S Othello St and S Alaska St
  • Rainier Ave S, between S Alaska St and S McClellan St

What to Expect during Crack Seal Projects

The impacts of crack sealing are minor compared to a repaving project, but there are some impacts. 

PARKING RESTRICTIONS:  The work area covers from curb to curb, so parking will be restricted on both sides of the street during the day(s) of the crack sealing from 7 a.m. – 5 p.m.   “No Parking” signs will be installed 72 hours prior to start of work.  The parking restrictions are typically removed as soon as SDOT crews complete the maintenance work. 

SCHEDULE: Weather permitting, SDOT crews plan to start the crack sealing operation in early August.  “No Parking” signs will be installed at least 72 hours prior to the start of work, which provides a good indication of the timing of the upcoming work.  If you need more information regarding the schedule, please contact us.  

LANE CLOSURES: There will be no full street closure during the operation.  SDOT will keep one lane open in each direction. Lane closures may last approximately 3 to 4 hours.  Traffic flaggers will be present during maintenance work.  Sidewalks will remain open at all times.

ACCESS TO ALLEYS AND DRIVEWAYS:  Access to driveways or alleys may be disrupted for a few minutes during the day of the work, but SDOT crews will work to minimize any delays and will provide assistance as needed.
