2007 Sealcoat Project No. 07-04: Authorize Preparation of Plans
& Specifications
REQUESTED ACTION
Authorize preparation of plans and specifications for the 2007 Sea1coat Project
No. 07-04.
DISCUSSION
A sealcoat program is a cost-effective tool to protect street capital asset and
extend the life of the street system. Sea1coatmg is the application of asphalt
emulsion followed immediately with an aggregate cover. Sea1coating of streets is
beneficial because it:
.
Delays or eliminates further aging of pavement due to water and sun.
Seals to provide a moisture barrier.
Fills in raveled pavement areas.
Enriching under-asphalt pavement.
Seals cracks temporary or permanently.
Performs minor leveling.
Restores surface friction.
Economically prolongs the life of existing pavements.
.
.
.
.
.
.
.
Sealcoating remains to be one of the most cost-effective maintenance tools toward
pavement management. It is estimated that a sealcoat application extends the life
of pavement from three to five years at a fraction of the cost of street
rehabilitation or bituminous overlay projects. It is therefore more cost effective to
sealcoat roadways when pavement distresses are fewer verses letting the
pavement detenorate until major, costly rehabilitation or reconstruction projects
are reqUired.
In conjunction with the Pavement Management Program, staff has reviewed the
City's street network and IS recommending the streets shown on the attached map
to be sealcoated in 2007. The estimated cost for this project is $245,000. The
cost includes pnor street preparation work, traffic control and pavement markings
to match existing conditlOns. The project IS proposed to be bid in February and
The City of Chanhassen . A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play.

have construction start in July. By bidding the project out early, more
competitive bids are anticipated.
Funding for this project has been budgeted m the CIP (Pavement Management -
ST-018). Other projects will also use the pavement management CIP item funds.
These projects include the 2007 street project and the public works annual
materials (pothole patching, crack sealmg materials, spot concrete curb and gutter
repair and striping) purchases. The budgets for these projects are $140,000.
RECOMMENDA TION
At this time, staff is recommending Council authorize preparation of plans and
specifications for the 2007 Sealcoat Project.

This project will provide maintenance such as crack sealing, seal-coating, pothole patching for city streets. The projects will be determined
annually based on the pavement condition index as generated by the pavement management program.
Justification I
This will provide a centralized funding mechanism that will help reduce the effect on Genef<ll Fund operating expenditures.

This will reduce the need to reconstruct streets and will allow us to more closely match the life of streets to the utility lines that lie underneath
them This will allow better coordination when we need to replace water and sewer lines with replacing roads.
