(4)Wearing course shall conform to
NYSDOT Specifications for Type 6F hot bituminous concrete plant mix
and shall be rolled to the required thickness.
| ||
(5)Pavement marking shall be yellow
reflective paint and shall be placed down the center of the paved
roadway in accordance with the directions of the Highway Superintendent,
per NYSDOT Specifications.

(6)The Planning Board shall have
the right to modify the above minimum standards to meet specific and
unusual conditions.
