Background:
Much of the curb and gutter placed in the KC Metro between 1985 and 2008 was installed using local limestone aggregate that was of poor quality because it was relatively soft compared to previous sources of limestone rock. The aggregate still met local specifications, and worked well for buildings, foundations and most structures. However, when used for paving, curb and sidewalks, the aggregate was prone to fail within 10 years. The frequent and harsh freeze-thaw cycling, combined with wet conditions, accelerated the concrete failure process “D-cracking” that disintegrates concrete from the inside out. The soft limestone absorbs water, then the water freezes; it expands and cracks the rock from the inside out. This process took several years to surface, and then time for the concrete industry and builders to adopt new codes, etc.
The purpose of the annual Curb Repair Program is to replace deteriorating curb and gutter on streets that are scheduled to be part of the City Overlay program in the following year. This year’s Curb Repair Program will be focused in residential neighborhoods and will replace 65,494 lineal feet of curb and includes the renovating of 74 sidewalk ramps to comply with the Americans with Disabilities Act.
