Pavement Maintenance Program

The purpose of the City’s pavement maintenance program is to use a priority system for the effective and economical repair of deteriorated pavement and the preservation of good pavement. Several factors contribute to the prioritization of repairs, including safety, pavement condition, traffic volume, ongoing programs, and future projects.

In order to record pavement conditions objectively, the City uses the Lucity computer program to interpret the type, severity, and extent of the cracks, potholes, and other issues found with the pavement and to turn this information into a street’s pavement condition index (PCI). The PCI is a numerical rating on a scale of 0 to 100, where 0 represents a failed street and 100 represents a perfect street.

Pavement conditions are useful only if they are current. Therefore, City staff typically review at least one fourth of the City’s streets each year.

FY2019–FY2021 Pavement Program projections

 
The City typically uses five major programs to improve, repair, and maintain its pavement network. Staff reviews the pavement conditions each winter and spring and makes recommendations of which streets to include into the annual programs to the City Council as part of the Capital Improvement Plan process.  Each program is evaluated on an annual basis for that year's work and for the work that is expected in the next few years.  The programs for the FY2019–FY2021 construction seasons are briefly described below.

Asphalt Pavement Resurfacing

This project involves removing and replacing the top few inches of asphalt pavement and is generally performed on asphalt streets with significant deterioration.

Concrete Pavement Replacement


The concrete pavement replacement project involves the removal and replacement of failed concrete pavement and curbing. Streets are included in this program to address a specific hazardous section, to support other pavement programs, or to make an overall improvement to a deteriorated street.

Microsurfacing


Microsurfacing is a surface seal that helps preserve asphalt pavement that is in good condition and that can be used to delay asphalt resurfacing. The City’s Public Works crews typically begin pavement repairs on streets in this program up to a year in advance of the microsurfacing. This project typically concentrates on neighborhoods rather than individual streets.

Reconstruction


Roadway reconstruction is reserved for streets that have reached the end of their useful lives and can no longer be maintained.

Sidewalk Improvements


The City dedicates approximately 10% of its annual pavement maintenance budget for sidewalk improvements, with the goal of bringing its entire sidewalk network into compliance with current accessibility standards. Curb ramps, broken sidewalk, and tripping hazards are included in this program, which often coincides with or precedes roadway improvements on the same street.

Grant Projects


Federal grants have greatly assisted the City in maintaining its major roadways. Past grants have partially funded projects to improve New Ballas Road (2008), Spoede Road (2010), Conway Road (2012), Graeser Road (2014), Coeur de Ville (2016), Emerson Road Sidewalk (2017), and Warson Road (2018). Upcoming grant-funded projects include:

North new Ballas Sidewalk Improvements


A new sidewalk will be added to the west side of North New Ballas Road to connect the sidewalk at Ladue Road to the sidewalk in front of De Smet Jesuit High School.  Construction is expected to begin in early 2019.

Emerson Road Improvements


Improvements to Emerson Road will include minor roadway widening, adding a curb to both sides of the street, and roadway resurfacing to improve the safety of this street.  These improvements will complement the sidewalk that was constructed in 2017 and will complete the work envisioned by the Emerson Road concept plan that was completed in 2011.  This project is currently in the design phase, and construction is expected in 2020.
