Commissioners approve Hall Brothers Onyx sealant project for Banner Road at $196,692.90
Summary
The Lincoln County Board of Commissioners approved a $196,692.90 contract with Hall Brothers to apply a proprietary Onyx sealant to 7.6 miles of Banner Road (project C562517); county staff said the product has been used elsewhere with positive results and recommended the procurement without competitive bids due to product uniqueness.
The Lincoln County Board of Commissioners voted to approve a proposal from Hall Brothers to apply an Onyx surface treatment to 7.6 miles of Banner Road (project C562517) on April 21, authorizing the chair to sign the contract for $196,692.90.
County highway staff described the product as a patented, polymer-based mastic intended to seal and restore surface aggregate and to extend pavement life. “This product we’ve been looking at... they use it a lot in Dawson County with great results over the past 4 to 5 years,” Jason Schultz, Lincoln County Highway superintendent, said during the presentation. Staff said the material is applied as a slurry, can be opened to traffic quickly and may extend reseal intervals compared with standard treatments.
Why it matters: Highway staff and outside reviewers said the treatment is preventive — aimed at preserving pavement and delaying overlays — and could reduce long-term pavement costs when used as part of a maintenance program. Commissioners discussed traffic and wear concerns, reapplication intervals and how the treatment would affect future milling and overlays.
Technical and schedule details: County staff said Hall Brothers would treat a 7.6-mile segment from Brady, south and east along Banner Road and that the county has $200,000 budgeted for the line item this year. Staff estimated Hall Brothers could complete the work in late May or early June. Tom Warbleau of TC Engineering, who reviewed the product with county staff, said a future mill would remove the treatment if an overlay were later required: “A mill would take it off. So if you wanted to overlay, it wouldn’t be much to mill it and overlay.”
Procurement and vote: Deputy county counsel advised the board that the Onyx product is highly specialized and unique to the supplier, and the county concluded there was no requirement for competitive bids in this instance. A motion to approve the Hall Brothers proposal for project C562517 in the amount of $196,692.90 passed on a roll-call vote (tally recorded as 5–0). The motion authorized the chair to sign the contract.
Ending: Commissioners asked staff to monitor the treated roadway and Dawson County’s nearby installation for performance data and to include anticipated retreatment in future budgets.
