Chip sealing in process

Via the DPW: 

"More preventive/improvement road surface work! This process is called “chip sealing”.  

Hot emulsion (liquid asphalt) is applied to the roadway surface and then aggregate stone is added and rolled in. Once the emulsion cools and hardens, it holds the stones in place.  

Excess stone is swept up during the process and the days after. This process is a very cost-effective way to extend the life expectancy of the roadway surface. It not only seals the roadway to prevent potholes, it also adds traction to the surface.  

This process can only be done during a certain time of the roadways life cycle, i.e. it cannot be done if the roadway has deteriorated too much.  

Many times we will crack seal or repair sub-surface problems before chip sealing."

The updated road conditions report was published here ->   https://www.franklinma.gov/sites/g/files/vyhlif10036/f/uploads/10a._pavement_management_report.pdf

Note that the report shows the priority of the road conditions, it does not provide a timeline for repairs. That is budget dependent. The Town voted down a dedicated override to fund road repair in 2014.
