The Selectmen have directed the DPW to apply Micro-Surfacing to the chip sealed side streets. The Micro-Surfacing contractor has looked at the streets and is confident that their product will resolve the loose stone and sticky tar issues.
Before applying the Micro-Surfacing the streets will be swept; sweeping should be getting underway this Friday.
We are penciled for Micro-Surfacing on July 10th through 12th.
These dates cannot be firm as weather will affect their work schedule.
Micro-Surfacing is a water based thin course pavement surface product. It dries to a hard finish in about an hour. It does not remain sticky and is designed to smooth the surface and encapsulate the tar areas of the chip sealing.
Due to the drying requirement, driving on it before it sets must be avoided. Therefore, you will have a window of approximately an hour after they pass your driveway when you will not be able to leave or enter. DPW Staff will be on site, working to notify you of the approximate time when you will have limited use of your driveway.
Micro-Surfacing is fairly large scale operation. When you see the equipment on your street please be prepared for driveway access limitations.
The process of Micro-Surfacing over chip seal is known as CAPE SEAL. Cape Seal is widely used as a pavement preservation procedure.
I hesitate to guarantee that this will finally resolve the issue, as nothing has gone as expected on the chip sealed side streets, but this is the logical next step. It has worked in other towns where the chip seal has been an issue, and it is a proven process.
Although we are desperately trying to solve this chip seal problems; it is not a wild desperation play.
Thanks again for your patience.
