A.
The contractor shall construct a two-course bituminous
concrete pavement laid to conform to the required grade, thickness
and cross section shown on the plans and in the specifications. The
top course shall not be placed until construction has been substantially
completed as determined by the Town Highway Superintendent. No heavy
equipment shall be allowed to travel on the top course.
B.
Materials and the method of construction shall conform
to Section 401 of the current Standard Specifications of the New York
State Department of Transportation. The base course shall be Type
3; the final wearing course shall be Type 7.
C.
If the initial course has been completed for an extended
period of time, it shall be thoroughly cleaned of all foreign materials
and a tack coat of asphalt emulsion applied to the surface at the
rate of 0.1 to 0.2 gallon per square yard prior to placing the final
wearing course. A final wearing course of fine asphaltic concrete
shall be uniformly spread by a self-propelled mechanical spreader
equipped with tamping bars and heating unit and in sufficient depth
to provide the required finished compacted thickness after rolling
thoroughly with a two- or three-wheel tandem roller weighing approximately
10 tons.
D.
Extreme care shall be exercised in placing of the
bituminous concrete to ensure that all longitudinal joints are lapped
in the placing of adjoining strips and that all lateral joints are
trimmed before continuing the placement of additional material.
