An Ordinance
Ordering the Improvement of
Main Street, in the City of
Paris, Ky, from the South
Side of Tenth Street to the
North Side of Bank Row,
with B tuIithic Paving.

Council or the City OF Paris:
Section 1. Main Street in the City
of Paris, Kentucky, from south side
of Tenth Street to north side of
Bank Row, is hereby ordered
improved by the removal of
the present wearing surface thereon
and by the construction of wood,
block, or vitrified brick or bitulithic
paving upon the present concrete
foundation. Said improvement, if BIZ
tulithic paving is used shall be made
in accordance with the specifications
hereinafter provided.
Section 2. The said improvement
shall be done at the exclusive cost of
the City of Paris. and shall be paid for
in cash upon completion and accept
ance of the work.
Section 8. Said improvement shall
be done in accordance with the follow
ing specifications:
SPECIFICATIONS:
The present wearing surface shall
be removed from the present con-
crete foundation, and all material so
removed shall be deposited by the
contractor at the city quarry or at any
other points which may be selected
by the Mayor, such points, however,
to be no further distance from the
point of removal than the city quarry.
Upon the present concrete founda-
ton shall then be laid the following
wearing surface:
Such wearing surface shall be COM
posed of hard crushed stone, sand and
bituminous cement, and shall have
the thickness, when compressed, of
two inches.
In preparing the mineral aggregate
for the above wearing surface the fol-
lowing method and apparatus shall be
used
The several grades and sizes of
mineral aggregate shall be accurately
measured in proportions previously
determined by laboratory tests to
give the best results, that is, the most
dense mixture of mineral aggregate
and one having inherent stability,
heated in rotary mechanical heater,
SO designated as to keep each batch
by itself until heated and then pass
into rotary mixer; or the varying
sizes of stone approximately proper
toned shall be fed into an elevator
terminating and discharging into rO-
tary dryer, and, after heating, the
stone shall be elevated and passed
through a rotary screen having Sec
tiOns with various size openings. The
minimum screen opening shall be a
one-tenth inch, and the maximum
shall not be greater than one and one
half inch. The difference in the width
of openings in successive sections
oh oil pnf fO,r I, ,nh ~
sections having openings smaller than
One-half inch, and shall not exceed
one half inch in sections having open
ings greater than One-half inch. The
several sizes of stone thus separated
by the screen sections shall pass into
a bin containing sections or compart-
ments corresponding to the screen
sections. From these compartments
the stone shall be drawn into weigh
box resting on multi-beam scale The
several sizes of mineral aggregate, af-
ter being separately weighed and
measured as above, xhall be dropped
into twin pug or other approved
form or mixer. In the mixer btu
lithic cement shall be added in suffici-
ent quantity to coat all particles and
fill such vOids as remain untitled by
the proportiOnment of the mineral ag-
gregate. The aggregate shall be so
proportional as to secure in the ag-
gregate inherent stability, density
freedom from voids and resistance to
displacement, and a mixture which
when combined with the bitulithic &C.
ment and cOmpacted together will
form bituminous street pavement
structure containing mixed mineral in
gradients of such grades as will give
the structure inherent stability, and
one in which the largest and smallest
piece are associated with each other
Unfortunately throughout the
structure, and in which the plastic BIZ
luminous composition permeates the
entire mass, uniting the various sized
particles thereof; filling the vOids and
forming the wearing surface. If the
crushed stone does not contain |
finely divided particles to fill the |
small voids in the aggregate, the de- |
ficiency of these finely divided parti- |
cles shall be made up by the addition |
of sand or other suitable fine mineral |
matter. /
The mineral aggregate shall be |
heated and mixed with a bitulithic |
cement at temperature consistent |
with good workmanship. The whole |
mixture shall be hot enough when |
reaching the street to be capable of |
being spread and raked without diff
ficulty, and not SO hot as to injure the
bitulithic cement.
There shall be spread over the BIZ
tulithic surface mixture a seal coat,
using per square yard of bitulithic
pavement approximately one-fourth
gallon of bitulithic cement, into which
shall be incorporated approximately
twenty-five pounds of mineral aggre-
gate not larger than One-Quarter inch
diameter After spreading the seal
coat, it shall be thoroughly rolled in
to the bitulithic surface mixture
Each layer of the work shall be
kept as free as possible from dirt, SO
that it will unite with the succeeding
layer.
The bituminous composition or &C.
ment shall in each case be free from
water, and shall be especially REIN
