6. ASPHALT PAVING
a. GENERAL - Only contractors who are experienced in bituminous pavement
i construction and having the necessary mechanical equipment will be
permitted to construct the pavement. Because of the extent of the
territory in which these specifications are applied, it is mandatory
that the work involved in a specific area be established with the
owner's engineer. The owner's engineer is prepared to indicate
standards and finishes which are acceptable.
b. SUBGRADE - The subgrade shall conform to the relative lines and
grades shown on the plot plan. If the subgrade is to consist of
in place soil, it shall be cleared of vegetation, rubbish, or other
material detrimental to proper conipaction. The subgrade shall then
be compacted by rolling with adequate equipment to a firm, unyielding
surface under construction trucking equipment. See Excavation and
Grading, section 2 if subgrade is made of fill.
C. BASE COURSE - The base course shall be according to local state
highway specifications, and shall consist of quarry waste, crushed
rock, or crushed gravel of such charactor that it will compact and
thoroughly cement under watering rolling so as to make a hard
bonded base a minumum of 4 inch thick when compacted. It shall be
laid and compacted according to the applicable local state highway
specifications. See plot plan under general notes for type and
thickness of the base course.
d. FINISHED ASPHALT_ SURFACE - The bituminous wearing surface shall be
a minimum compacted thickness of 2 inches, laid in two separate
\ courses. See the plot plan under general notes for the.specific
requirements. Mineral aggregate and bituminous material shall
meet local state highway specifications and must be controlled and
mixed in a central mixing plant. Approximately 20% of the mineral
composition shall be 2 inch minus graded aggregate with sufficient
fines to assure a dense, smooth, well sealed surface. Thorough
rolling and cross rolling with adequate equipment to give a well
knit even textured surface is required. This is intended as a
performance type specification and the contractor is advised to
consult with the oimer's engineer in conjunction with the general
notes on the plot plan for each specific job.
