Pavement Management Program (ongoing)

Through timely maintenance of streets, we are better able to provide safe roads on which you can travel. Studies have shown pavement conditions worsen at an increasing rate as the pavement gets older. Restoration of pavement near the end of its service life typically costs four to five times more than preventive routine maintenance.

We use a variety of rehabilitation techniques to keep Lenexa’s roads in good condition. The technique we choose depends on the condition of the road and value of the treatment, among other factors.

Crack seal

Crack seal is usually a first defense against pavement deterioration and is typically done to newer roads with small problem areas. Crack sealant is applied to cracks to prevent water and other materials from getting into cracks. 

Mill and overlay

A mill and overlay is intended to replace a failing surface. It consists of milling off the top portion of the street and replacing approximately 2 inches of the surface. This technique extends the life of the road in a more cost-efficient manner than a complete reconstruction. 

Reconstruction

Reconstruction entails removing and replacing the existing roadway, curb and gutter, and performing any needed subgrade modifications. It is the most expensive of the rehabilitation methods.

Ultra-thin bonded asphalt surface 

Ultra-thin bonded asphalt surface (UBAS) is a preventative maintenance tool used to help extend the life of a road by placing a thin, coarse aggregate hot mix over a special asphalt membrane. The membrane prevents water leakage and provides a superior bond to the old asphalt. The overlay can disperse water quickly off the surface, which reduces roadway spray from vehicles and provides greater visibility in wet weather. UBAS can be installed quickly, and it lasts several years longer than microseal.

• Concrete: Typically, three days is required until motor vehicles are allowed to drive on it.

• Micro surface: Please wait until the contractor has removed all cones and barricades. The drying time for these treatments varies based on weather conditions.

• Granite seal: You can drive on a granite seal right after it is applied. Please drive slowly and avoid braking sharply within the first few hours.

• Ultra-thin bonded asphalt: You can drive on UBAS right after it is applied.

The new curb was sprayed with a curing compound. This compound has a white pigment for installation. The "whiteness" of the curb will fade over time.

Much of the concrete used before 2002 consisted of soft limestone aggregate, which caused cracking. Most of our driveways and curbs have signs of this. Once the cracking occurs, the only fix is to remove and replace the curb. If we do not replace it at the time we are there, it will be completely deteriorated before we return the next cycle.

As sidewalk settles or is raised by tree roots, trip hazards are created. Generally, anything over 3/4 inch is considered a trip hazard. This does not warrant complete replacement of the sidewalk. Instead, the grinding is an effective way to remove these trip hazards.

Our contractor for the Pavement Management Program will make the repairs. You will not be reimbursed if you choose to have your own contractor make the repairs. Please submit a service request.

Lawns damaged by construction will be seeded. You should water the newly placed seed at a rate of 3 inches per week in five or six applications per week, until the roots of the grass are anchored in place.
