Deschamps Lane from Mullan Road to LaValle Creek (one mile). Public Works will use asphalt millings received from MDT in 2022 to create an adequate base and to elevate the road above the surrounding ground, greatly improving the surface water drainage that causes severe surface distresses in the current gravel surfacing annually. That base will be treated with an asphalt rejuvenator to aid in re-binding the asphalt content still available in the millings. Since this road is heavily used by commercial traffic, a traditional hot mix asphalt surface may be included in this work. We are currently working with a geotechnical engineering consulting firm to decide the most cost-effective structural option.

Indreland Road from Highway 93 to the end of maintenance (1.07 mile). Asphalt millings from an active MDT project in 2023 will be delivered by MDT’s contractor and laid out by County staff. An asphalt rejuvenator will be used with the millings to aid in re-binding the asphalt contained in the millings. A hot mix asphalt surface is not currently planned with this work, but a chip seal is tentatively planned for 2024.

Mill Creek Road in Frenchtown from Spring Hill Road to the end of maintenance (1 mile). Asphalt millings from an active MDT project in 2023 will be delivered by MDT’s contractor and laid out by County staff. An asphalt rejuvenator will be used with the millings to aid in re-binding the asphalt contained in the millings. A hot mix asphalt surface is not currently planned with this work, but a chip seal is tentatively planned for 2024.

All streets in Piltzville (0.62 mile) The streets in Piltzville were asphalt until 2019, at which time they were beyond repair. Pulverizing the asphalt and incorporating it with a gravel base material provided a maintainable gravel surface and Public Works plans to replace the asphalt surfacing. Budget restrictions in the past have prevented that work, but the recent availability of asphalt millings and a chip seal program provides a suitable option for providing hard surfaced roads. Since chip seals are planned in nearby East Missoula and West Riverside, this work will be incorporated into the 2023 work plan.
