b. Construction.
(1)
Equipment.
(a)
All equipment, tools, machinery and other appliances used in
handling materials and performing any part of the work shall be subject
to the approval of the City Street Superintendent before the work
is started and whenever found unsatisfactory shall be changed or improved
as required by the City Street Superintendent. All equipment, tools
and machinery must be maintained in a satisfactory working condition.
(b)
The mixing plant shall conform to the "Standard Specifications
for Bituminous Mixing Plant" requirements of ASTM Designation D 995,
the latest edition thereof.
(c)
Pavers shall be mechanical self-powered machines capable of
spreading the mixture true to the line, grade and crown as specified.
(d)
Rollers shall include a self-powered steel wheeled roller and
hand tamps. Steel wheeled rollers shall weigh not less than five (5)
tons and they shall be equipped with adjustable spring scrapers fitted
to the driving and steering wheels. They shall also be equipped with
sprinkling systems which will uniformly moisten each wheel. Wetting
devices such as coco mats shall be included when necessary. In order
to obtain a smooth surface on driveway approaches or steep grades,
a smaller vibrator roller shall be used in rolling as required.
(2)
Methods.
(a)
Whenever it is necessary to carry traffic over the roadway during
priming operations, the prime coat for absorbent surfaces shall be
applied in lanes approximately one-half (½) the width of the
base at the time and shall be permitted to cure before the application
is made to the remaining one-half (½) width. The prime coat
for non-absorbent surfaces may be applied full width, provided the
primed surface, including entrances and side roads, is blotted with
sand, in such a quantity as specified by the City Street Superintendent,
before it is opened to traffic. Unless sand or other blotting material
is spread, the contractor shall prevent traffic from using the primed
surface until it is cured. It shall be the contractor's responsibility
to maintain or restore the completed primed surface in such a manner
that a smooth, uniform surface will be available for the asphaltic
concrete.
(b)
The mixture shall be transported from the paving plant to the
work in tight vehicles with metal bottoms previously cleaned of all
foreign materials. The truck beds shall be raised and the inside lubricated
to prevent the mixture from adhering to the bed. An excess of lubricant
will not be permitted. Each load shall be covered with canvas or other
suitable material of sufficient size to protect it from the weather.
(c)
The mixture shall not be spread unless the ambient temperature
is forty degrees Fahrenheit (40°F) and rising and only upon a
surface which is dry and when weather conditions are suitable. The
mixture shall be delivered on the job at a minimum workable temperature
of two hundred fifty degrees Fahrenheit (250°F). Except as otherwise
specified herein, the mixture shall be spread by means of an approved
mechanical paver and finishing machine as herein specified. Mixtures
shall be dumped in the center of paver hopper and care exercised to
avoid overloading and spilling over of the mixture upon the subgrade
or base. Pavers shall operate at such speed as may be indicated to
insure a smooth riding surface and the mixture shall be delivered
to the paver at such a rate as will enable the paver to be operated
continuously.
(d)
The mixture shall be thoroughly and uniformly compressed by
steel wheeled rollers, as soon after being spread as it will bear
the weight of the roller without undue displacement. Delays in rolling
freshly spread mixture will not be tolerated.
(e)
After final compression, the surface shall be smooth and true
to the established crown and grade. It shall have the average thickness
specified and shall at no point vary more than one-quarter (¼)
inch from the specified thickness. Any low or defective places shall
immediately be remedied by cutting out the course at such spots and
replacing it with fresh hot mixture which shall be immediately compacted
to conform with the surrounding area and shall be thoroughly bonded
to it. The finished pavement shall be set free from depressions exceeding
one-eighth (⅛) inch as measured with a ten (10) foot straight
edge paralleling the centerline of the roadway. No traffic shall be
permitted on the finished pavement until it has cooled to atmospheric
temperature. After final compression, all compacted mixtures shall
have a density not less than ninety-five percent (95%) of the maximum
possible density of a voidless pavement composed of the same materials
in like proportions. If the density of the finished base courses and
surface course is less than ninety-five percent (95%), additional
rolling will be required. Additional rollers, of the type and weight
herein specified, shall also be furnished by the contractor if, in
the opinion of the City Street Superintendent, they are necessary
for property compaction.
(f)
Longitudinal and transverse joints shall be made in a careful
manner. Well bonded and sealed joints are required. Joints between
old and new pavements or between successive day's work shall be carefully
made in such a manner as to insure thorough and continuous bond between
the old and new surfaces. Hot smoothers or tampers shall be carefully
employed in such a manner as to heat the old pavement sufficiently
(without burning it) to insure a proper bond.
c. Inspection and testing.
(1)
General. All materials and work shall be subject
to inspection at all times by the City Street Superintendent or his/her
duly authorized representative and no materials shall be delivered
or accepted nor work performed without proper authorization of the
City Street Superintendent. In order to assure the use of suitable
materials, the City Street Superintendent shall have the right to
make any inspection he/she may deem necessary, either at the plant
of the contractor or his/her supplier or on the job site. The City
Street Superintendent may at any time authorize the collection of
samples of materials from any source he/she may direct and subject
them to tests provided for in these specifications by a testing laboratory
approved by him/her for determination of their quality and fitness
for work under this contract. The expense of such sampling and testing
shall be borne by the City. The contractor shall afford such facilities
as may be required for collecting samples.
(2)
Mixing plant inspection. The City Street Superintendent
or his/her authorized representative shall have access at any time
to all parts of the mixing plant in order to ensure the manufacture
of the mixture in strict accordance with these specifications. In
order that accurate and sufficiently large samples of aggregates may
be obtained from the bins over the mixer, easy and safe access shall
be provided to the location of the plant where such samples may be
taken. The mixing plant operation shall conform to the applicable
requirements of the Missouri State Highway Department specifications.
(3)
Determination of bitumen content. Bitumen
content shall be determined in accordance with the requirements of
the ASTM Designation D 1097, the latest revision thereof.
