The contractor will build portland cement sidewalk or asphaltic cement
sidewalk conforming to the standards of the Town of Southport for sidewalks,
and in conformance with line and grade designated by the Town Highway Superintendent.
The mix will be a "Six Bag Mix" (564 pounds of portland cement per cubic

State specifications for Item 18. Acceptable slump will be from 2 1/2
inches to 3 1/2 inches.
Either quilted covers, waterproof blankets or an approved sprayed or
painted curing compound may be used. Except when a curing compound approved
by the Town Highway Superintendent is used, sidewalks shall be cured for a
minimum of three days. In any case, traffic will be prohibited for at least
24 hours.
No portland cement concrete sidewalk work will be done after November
15 of the current year or before April 15 of the following year.
The material shall conform to the New York State Department of Public
Works Standards for Item 5 1A Hot Mix Asphaltic Concrete.
Metal edging is available for sidewalk work, but is not a requirement.
