Summary
Platte County awarded the microsurface portion of its February 2025 road resurfacing project to Vance Brothers LLC for $613,186; county staff explained microsurfacing is a thin asphalt cap that fills small cracks and cited its expected thickness and purpose.
Platte County commissioners voted May 5 to enter a contract with Vance Brothers LLC for the microsurface portion of the county’s February 2025 road resurfacing project, with a budget impact of $613,186.
Public Works staff described microsurfacing as a thin asphalt product — roughly one-quarter to three-eighths of an inch thick — that acts as a cap over existing pavement and fills small cracks up to about a quarter inch in width. The director said the surface contains finer aggregates and will extend pavement life by sealing minor defects.
County staff told commissioners the contract award followed a previous bid process and that the county auditor certified funds were available. A motion to approve the contract passed 3-0. Commissioners asked clarifying questions about the difference between microsurfacing and other resurfacing methods; staff described microsurfacing as a seal-like treatment rather than a thicker asphalt overlay.
The contract covers the microsurface work only; schedule and lane closures were not discussed during the meeting.
