RE: Wal-Mart Sewer Offsite – SPR–0-0091-YL
Roadway Restoration
Dear Mr. Wood:
During our sewer inspections we noted that the roadway section was different than expected. I met our Public Works Director onsite (Grove Rd) and inspected the roadway at his request.
The existing roadway was expected to have a ballast section and a crushed rock top coarse under the wearing surface. Under this premise, the City of Yelm approved a grind and overlay
approach to restoring this roadway following the sewer installation. However without an existing road base, the grind and overlay restoration will not provide an adequate driving surface
that can be warranted.
At this time it is the City of Yelm’s requirement to over excavate the lane that is to be restored and rebuild this section with the following:
8” Gravel Base
2” Crushed Surfacing Top Coarse
2” Class B Asphalt Concrete
And to overlay the opposite lane with:
2” Class B Asphalt Concrete
Following the paving of the roadway the shoulder will need to be graded to provide an even transition from the asphalt surface to the gravel shoulder.
If you have any additional questions or comments please do not hesitate to call or contact me at jimg@ci.yelm.wa.us.
