The Montgomery County Department of Transportation’s pavement preservation program is using long-term strategies to preserve and enhance the County’s transportation infrastructure. Under this program, roadways rated as fair or worse began receiving attention in the Spring once the weather became warm enough to allow for the use of hot mix asphalt.
The work consists of the following steps:
- Full depth patching removes and replaces distressed pavement areas to restore the pavement’s structural integrity and ability to support vehicle loads.
- Edge and full-width pavement milling removes the entire surface of the roadway to a depth of one to two inches.
- Utility adjustments to bring storm drain and sewer manhole covers and valves to the same grade as the renewed pavement.
- Crack sealing to repair large cracks with a flexible filler.
- Concrete curb replacement (if needed or appropriate) to remove and replace damaged and misaligned curbs.
- Paving with hot mix asphalt.
- Replacement of roadway lane markings.
Resurfacing using hot mix asphalt is planned for the following arterial roads: Brink Road between Laytonsville Road and Route 124 (Woodfield Road) in the Gaithersburg East area; and Clarksburg Road between Bethesda Church Road and Price’s Distillery Road and Bethesda Church Road between Clarksburg Road and the Frederick County line, both in the Damascus area.
Arterial roadway preservation using micro paving is ongoing for Norbeck Road between Layhill Road and New Hampshire Avenue.
Highway Services is also resurfacing neighborhood streets in the Indian Springs community of Silver Spring.
