2017 Roadway Surface Treatment
THE ROAD SURFACE TREATMENT PROCESS
1.Any serious structural defects are identified and repaired
2.A lever, shim course is applied to the existing paved surface. It is design to:
•Redefine the profile of the road
•Provide some structural stability
This course is not a standalone finished surface, as the various thicknesses are not designed to withstand traffic volumes over time, harsh New England winters, or stormwater runoff.
1.All water, sewer, drainage, and utility structures are raised to grade
2.Driveway aprons are adjusted as needed
3.Rubber chip seal is applied
4.Roads are swept immediately after and on a regular schedule to remove loose stone
5.All traffic markings are then restored
TYPES OF ROADWAY SURFACE TREATMENTS
BONDED WEARING COURSE is an asphalt product that the Department utilizes to extend a road’s service life while awaiting future utility work. This product seals and protects the surface of the roadway and provides superior bonding of the ultra-thin mix to the pavement. This treatment requires the adjustment of structures and the restoration of traffic markings.
RUBBER CHIP SEAL is a surface treatment takes place on neighborhood roads with lower speeds and reduced traffic volume. This process is an efficient way to provide neighborhoods with a more rideable surface. Surface defects are repaired before an area receives a thin leveler course. This Hot Mix Asphalt (HMA) treatment improves the profile of the road and improves surface drainage. The HMA also provides some structural stability for the road; however, since it is a thin layer, it will not withstand traffic volume overtime or harsh winters. After structures are adjusted, a rubber chip seal treatment is applied. Any loose stone is swept on a regular schedule.
During the 2017 construction season, the Department has scheduled the following roadways for Surface Treatment:
- Blackberry Lane
- Blueberry Circle
- Birchmeadow Circle
- Bancroft Circle
- Lavalle Lane
- Surro Drive
Roadways have been leveled with a thin layer of Hot Mix Asphalt and are in the process of receiving the Rubber Chip Seal Surface Treatment. Casting adjustments are in progress.
