Paving and Slurry Seal 2018

Summertime weather makes for ideal paving conditions. Tigard typically uses two types of pavement treatments: 1) pavement overlays on busy streets and on roads with severe cracks and potholes to restore the road to good pavement condition; and 2) slurry seals on streets that have lower traffic volumes and are in relatively good condition to maintain them in good condition.

SLURRY SEAL

Note: Due to equipment issues in California, the contractor has postponed slurry seal work for two days. The schedule below reflects the new project dates.

Intermountain Slurry Seal, Inc. will be slurry sealing many streets in northern Tigard in late July and early August.  A slurry seal is a liquid mixture of thick oil, sand, and other additives applied to the surface of a roadway to extend its life by restoring the asphalt binder near the pavement surface. Work will involve closing the street from 7:30 am to 5 pm while the slurry is applied and as it dries. Residents will receive a mailed notice and map with dates a couple of weeks before slurry seal and a door-hanger a couple of days before slurry seal.  The current schedule is:

Frequently Asked Questions


How will the slurry seal application affect me?

  • Your street will be closed for one day from 7:30 a.m. to approximately 5 p.m. When the slurry seal is applied, it looks like chocolate syrup, but is much stickier and messier. Slurry seal takes several hours to dry. During that time, motorists, pedestrians and pets must stay out of the slurry seal so as not to ruin the application and to avoid getting slurry seal on vehicles, shoes and paws.
  • You must remove all vehicles and other objects from the street. This includes trailers, garbage cans, basketball hoops, etc.
  • You must avoid outdoor water use if it causes water to flow onto the street. Water will hinder the slurry seal curing process. If you water your lawn or wash your car on slurry seal day, please make sure the water does not flow onto the street.

When will my street be closed for the slurry seal application?
Check the maps provided on this page to determine which day your street is scheduled to be closed. A couple days before the closure, you will receive a door hanger notice and signs will be posted along your street. We do our best to adhere to the schedule, but wet weather and other factors can cause delays. If your street closure date changes, you will receive a new door hanger notice and the signs along your street will display the updated street closure date.

What if it rains?
Light rain or passing showers may not delay the slurry seal application. However, slurry seal cannot be applied in heavy or steady rain. If we have or anticipate significant rainfall, the slurry seal application is likely to be postponed to another day. You will be notified of the new application date via a door hanger notice and signs along your street.

What if I need to drive somewhere?
Park your vehicle on a nearby street that is not being slurry sealed. Use the provided maps and check area signage to plan your route and where to park.

What if there is an emergency?
Should an emergency arise, emergency vehicles will be given access to the street.

What about garbage pickup, mail delivery, etc.?
Slurry seal applications are coordinated with the Postal Service, garbage haulers and other service providers. In most cases, you will not experience any service interruptions. Put garbage cans out early on your regular collection day, preferably at the edge of your driveway rather than in the street. Garbage haulers and mail carriers will work around the slurry seal application to provide service— although it may not be at the usual time of day.

What does slurry seal do?
Residential streets tend to deteriorate due to weathering. Rain, sun and freeze/thaw cycles gradually wear down the pavement’s asphalt binder — the sticky stuff that holds the pavement together. In a slurry seal application, a liquid mixture of thick oil, sand and other strengthening additives is applied to the roadway. The mixture hardens as it cools and counters the effects of weathering by restoring the asphalt binder near the pavement’s surface.

How is slurry seal applied and what should I expect?

  • On the morning of the slurry seal, the street is swept by a street sweeper.
  • A liquid mixture of thick oil, sand and strengthening additives is poured from a truck onto the road surface.
  • While motorists can drive on the slurry seal application a few hours after it has been applied, it takes a couple of weeks to fully cure.
  • As the slurry seal cures, the street typically has a sandy coating. This sand is picked up by street sweepers once the curing process is complete.

How much does slurry seal cost and how is it paid for?
Slurry seal costs about $.30 per square foot and is very cost effective when compared to a complete pavement overlay, which costs about $3.00 per square foot. Slurry seal is paid for by Tigard residents and business owners through the street maintenance fee that appears on your monthly City of Tigard utility bill.

Who will apply the slurry seal?
The city has contracted with Intermountain Slurry Seal, Inc. to apply the slurry seal. City inspectors will oversee the work and can address any issues that occur during the project.
