Street Preservation is the process of planning the maintenance and repair of the street network to ensure the overall condition is maintained at the desired level of service.
The City maintains more than 1,200 lane miles of street pavement valued at more than $1 billion. Routine maintenance of streets is important to extend the life of the pavement, and a continued investment in street preservation is necessary to ensure our streets are adequately maintained.
If you have questions regarding the City's Street Preservation program contact the Pavement Coordinator at 913-971-9050.
Crack Sealing is a preventative maintenance process consisting of filling the cracks in the pavement with a rubberized sealant or asphalt product to prevent moisture from penetrating into the base and subgrade material.
Microsurfacing is an aggregate mixture of asphaltic oil, water and crushed rock that spreads over the street at about 1/4 to 3/8 inch thickness. The microsurface product "cures" when the water evaporates, leaving only the asphalt to coat the crushed rock. This treatment process protects the existing street surface from the effects of aging and oxidization and increases skid resistance.
Thin Lift Asphalt
Thin Lift Asphalt is an asphaltic-concrete overlay, which is used to level, waterproof, and restore the original street's shape and ride.
Asphalt Mill & Overlay
Asphalt Mill and Overlay is rehabilitation that includes minor repair to the ground below the pavement, asphalt base replacement, limited curb and gutter repairs, ADA-required sidewalk ramp improvements, and a 2" asphalt resurfacing.
Major Repair Mill & Overlay
Major Repair Mill and Overlay is rehabilitation that includes significant repair to the ground below the pavement, asphalt base replacement, extensive curb and gutter replacement and asphalt resurfacing of 2" or more.
Reconstruction is the process of replacing the entire street within the existing right-of-way and consists of improvements to the ground below the pavement; replacing the full depth asphalt or concrete pavement section; all of the curb and gutter storm sewer; sidewalks; and ADA sidewalk ramps. Reconstruction may also incorporate moderate changes to street alignment, profile, cross-section, and roadway width.
