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 are receiving attention now that the warmer weather allows for the use of hot mix asphalt.
The work consists of:
- 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.
Work on the following residential neighborhoods is scheduled to begin this spring: Glenview, Silver Spring; Regency Estates, Potomac; Rosemont and Walnut Hill, Gaithersburg; and Goshen Hunt, Damascus.
Arterial roads that will be resurfaced this spring using hot mix asphalt are: three miles of Seven Locks Road between Democracy Boulevard and Bradley Boulevard, Bethesda; three-and-one-half miles of Gainsborough Road between Tuckerman Lane and Democracy Boulevard; more than five miles of Twinbrook Parkway between Veirs Mill Road and Rail Road Bridge; and Travilah Road between Darnestown Road and Dufief Mill Road.
Arterial roads that will be resurfaced this spring using a micro surface process are: nearly seven miles of Tuckerman Lane between Seven Locks Road and Falls Road; 2.75 miles of Tilden Lane between Old Stage Road and Old Georgetown Road; and more than six miles of Observation Drive between Route 118 and Ridge Road.
In addition, DOT will repair sidewalks and curbs in the Connecticut Avenue Estates neighborhood, Rockville. The work involves removing and replacing damaged sidewalks and ensuring that curb ramps are accessible to comply with the Americans with Disabilities Act, removal and replacement of damaged and misaligned curbs and restoration of disturbed areas with soil, grass seed and straw mulch. While DOT is in the neighborhood, residents can take advantage of the competitive price offered by the County to replace driveway aprons (the portion of the driveway that is within the public right-of-way) and lead walks (the sidewalk from the edge of the road to a homeowners property line).
