Pavement Management Program

Pavement deterioration is cumulative.  Factors including weather, traffic, and frequency of maintenance all contribute to a road's longevity.  The Lee’s Summit’s Pavement Management Program is used to maintain or restore paved road surfaces, add structural capacity, and improve riding comfort and skid resistance.  While newly overlaid roads are aesthetically pleasing, roads are not overlaid to improve appearance.

Scheduled maintenance programs include:

  • Crack sealing: applying asphalt rubber into the crack to seal it and prevent water from getting into the street.
  • Curb Replacement: replace offset, damaged, or deteriorated curb, prior to an overlay.
  • Surface Sealing: a thin layer of aggregate, oil and asphalt binders are mixed together and spread over the existing pavement.
  • Overlay: milling off the top 1.5 to 2 inches of the street and replacing it with fresh asphalt to seal and revitalize the street.

Streets included in the City's annual resurfacing projects are carefully evaluated and inspected under the guidelines of the Pavement Management Program. Other repairs are made based on reports of problems from residents. Funding for the Pavement Management Program is made available through the 1/2-cent transportation sales tax.

For questions regarding the City’s pavement management program or the priorities for pavement repairs, surface sealing, and overlays, contact the Public Works Operations Division at (816) 969-1800.

Crack Sealing                      

CracksealAsphalt pavement, by design, is flexible to accommodate the freeze/thaw cycles of the climate. Subsequently, cracking will occur in relatively new pavement and continue throughout its life due to age, traffic, weather, etc. Crack "sealing" is the placement of a rubberized sealant in the crack that will provide a protective coating and seal out water. If the cracks are not maintained, the cracks can ravel and increase in size. Crack sealing is the most common maintenance option used to help protect the pavements integrity. It is often placed in advance of overlays and surface treatments to improve performance.  In addition to proper material preparation and application, a critical step in crack preparation is cleaning and drying the crack. After the cracks are cleaned and dried, using hot compressed air, they are filled with liquid asphalt emulsion. Excess sealant is leveled off at the surface using a squeegee. The air temperature during application should be 32 degrees Fahrenheit and rising. The best time to seal cracks is during the cooler winter months when the cracks are the widest (October-March).

Curb Replacement

In advance of the annual overlay program, the Public Works Department hires a construction contractor to replace a specific amount of curbing each year, for both residential and arterial streets. For curb problems not included in the replacement contract, the Operations Division sends out a crew to patch the curb with asphalt until a permanent fix can be made.

Surface Sealing

Surface Sealing is a surface treatment designed to extend the life of existing pavements by filling surface cracks and voids, sealing weather tight, and adding texture and uniform appearance to the street. Surface Sealing uses a pre-mixed slurry of rock, polymer asphalt binders, cement, and filler materials to seal the entire roadway at a depth of approximately 1/4 inch. Surface Sealing requires 4-6 hours to set up before it can be opened to traffic, but it takes in excess of 48 hours before it is completely cured. Once the street has been reopened, traffic, large vehicles, such as delivery trucks and garbage trucks, may leave scuff marks on the surface, surface marks may also be left from vehicles turning the vehicle wheels without the vehicle moving (power steering burns) which is completely normal and expected. As more traffic drives over the surface many of these marks will flatten out resulting in a uniform appearance.

In addition, there may be small surface rocks that will roll off into the gutter. This is also normal, and the contractor will sweep up the excess aggregate within 2 - 4 weeks following the installation of the surface seal.

During an overlay project, residents must remove all vehicles from the street. If a curb is present, the old pavement will be milled along each edge so that when the overlay is applied the surface of the new pavement will be aligned with the gutter. The street is then sprayed with a thin layer of asphalt called a tack coat to ensure the new pavement will adhere to the old pavement. Once the overlay is applied, it would be ideal for traffic to be kept off the new pavement for at least four (4) hours. However, traffic may travel on a newly paved roadway after it has been rolled once, but is normally reopened following a second rolling. Sharp turning movements on the new surface must be avoided until the pavement has had a chance to cure. Operations are performed to ensure at least one lane of traffic remains open at all times.
