Background
CIP No. 13048 – Citywide Slurry Seal Project
The Citywide Slurry Seal is a bi-annual project which uses a data driven approach to analyze and assess the City’s existing road conditions based on the most recent Pavement Management Program (PMP) update and Pavement Condition Index Scores (PCI). Based on the PCI score of each road, a specified slurry treatment is assigned.
Limits of work: Approximately 25% of all residential/local streets citywide consisting of 58 centerline miles and 11.2 million square feet of roadway to be resurfaced.
Improvements consist of: Crack Filling, Micro Milling, Manhole Adjustments, Slurry Sealing, and Signing and Striping.

What is Slurry Seal?
Slurry Seal is a mixture of liquid asphalt emulsion combined with sand or small gravel that’s applied to the existing asphalt pavement to preserve and extend its life.
There are 3 different types of Slurry Seal (Type 1, 2, and 3). The slurry type is differentiated based on the size of aggregate in the mixture. City staff determines the type of Slurry to be used on each road based on the PCI score from the City’s most recent PMP update.
A Slurry Seal is different from an asphalt overlay in that it is a much thinner layer of new surface that is being applied. Typically, asphalt overlays are utilized on major/arterial roads which receive a high volume of traffic and thus require a more advanced level of treatment/ rehabilitation. Slurry Seal is a cost-effective method of rehabilitation and preservation which allows the City to resurface and extend the longevity of the City’s low volume traffic local/residential roads.
