The Montgomery County Department of Transportation is in the process of applying a micro-surfacing materiel to extend the pavement life on the entirety of Riffle Ford Road running from Darnestown Road, Maryland Route 28 to Germantown Road, Maryland Route 118.
According the MCDOT, the work which began last Thursday will take six to eight weeks to complete, weather permitting. Drivers who use Riffle Ford Road can expect lane closures and flag men along portions of the road. “There will be daily single lane closures with flaggers to maintain the flow of traffic on the adjacent lane,” said Esther Bowring, spokesperson for MCDOT.
“We started pavement patching repairs last week in preparation of micro surfacing to be placed in a couple weeks, sometime in July,” said Bowring.
An MCDOT pavement evaluation has determined that, prior to resurfacing, full depth asphalt patching of the pavement or other repairs may be necessary at selected locations. Full depth patching restores the pavement’s structural integrity and capacity to support vehicle loads, according to a MCDOT newsletter. “An additional step may be necessary to seal large cracks that may not require full depth patching. A flexible filler material is injected into the cracks and sealed with a special tool,” said MCDOT.
The final step in the pavement preservation process is the dual application of the micro surfacing material. It is a cold applied liquid material containing a light sand aggregate that preserves pavement deemed to be in good condition. The material is uniformly machine applied and allowed to cure for several hours before opening to traffic. Additionally, this roadway preservation treatment enhances the existing pavement, fills cracks and small voids, and extends the life and serviceability of the pavement, according to MCDOT. The micro surfacing material will cover the entire road surface. This will provide for a uniform appearance and surface texture.
Alternating one-way traffic patterns may be used periodically and minor traffic delays may be experienced as flaggers manually direct traffic safely through the construction zone. Access to homes will be available at all times, however minor delays may be experienced as workers restrict traffic from driving on the freshly applied material. Traffic will be restricted from driving on the micro surfacing material until it is fully cured, usually for three-to-four hours.
