Many of our older concrete streets consist of 5" of concrete on top of compacted soil. Due to the extensive failures of the existing pavement, the concrete street and underlying soil will be removed, and a new cross-section will be constructed, consisting of 4" of rock and 8" of concrete. Slabs will be tied together using epoxy-coated steel rebars.
Please note that neither the existing nor new concrete is "colored" concrete. While there is some limestone-based concrete around the city, most of the concrete contains Meramec sand and gravel, which provides the orange/brown look. While the new concrete initially appears to be a bright white, over time, the color mellows and the top layer of cement wears off, revealing the brown sand and gravel underneath.
Project Update and Schedule
The 2020 Project will replace the remaining portion of Fairoyal Drive, from near East Royal down to Barrett Station. The entire street will be replaced, just as the north-south portion was replaced in 2018. While the street is being replaced, we are also planning drainage improvements along the north side of Fairoyal where groundwater consistently seeps across the sidewalk and into the street. An engineering consultant, HR Green, performed conceptual design and held an open house with affected residents in summer 2019, and they are now working on the final design. This is not a stormwater project, but a groundwater solution.
This project will be bid out in early spring, with work scheduled to start after Memorial Day.
