GRA01l'JG
The necessary grading shall first be done so that the pavement will
be constructed to Cl. suitable finished grade.
Grading shall include all cuts, fills and all earth and existing pave-
ment or rock or other material moving, and the removal of all obstructions
in the line of the improvem.,mt n~ces6ary to construct the roadway to the
cross-sections sho\:n on the dra-';v'ings. The subgrale sl1:111 be brou6ht to
the proper form and grade and shall be brought to a firm compacteJ surface
by rolling, tamping or otner suitabl.::: means. All soft and spongy spots
and all organic or perishable matter shall be completely removed frOlTi the
subgrade and the space filled with gravel, broken stone, broken concrete
or other suitable materials.
A transverse section of the finished surface of the pavement shall
be an 2.rc of a circle passing one -quarter inch ;:tbove the upper roadway
edges of the gutter flag ;:m,d the el.~vations of the crown line of sail finished
roadway at every point of the roadv..'ay of said streets between said. termini.
At street intersections the grade of said top surface shall be n"odified
to such a degr.;;e only as i6 necessary to make the top surface or said
intersecting roadv.rays conform to each other and to produce a smooth,
even surface.
The pavement sh211 be constructed on the prepared subgrade behveen
the curb and. gutter.
All organic material (black dirt or topsoil) 'which is removed in the
area to be improved as hereinbefore set forth shall be stockpiled on the
site and used for the final dressing and grading of the parkways. If, in the
opinion of the Engineer, the amount of organic material (topsoil) available
on the site is not sufficient to properly dress the parkways, additional
organic material (topsoil) shall be brought to the site and spread over the
-3-
~
parkways. The thickness of the organic material (topsoil) shall be not
less than four (4) inches.
The parkways, vihen complehd, shall be free of all stones, sticks,
gravel, clay material and all other debris and shall be graded in such a
manner that property owners adjacent to the improvements rnay sow grass
seed. without further grading of the parkwa.ys. Seeding of the parkways will
not be included in this improvement.
COMBINATION CURB AND GUTT8R
On each side of the roadway to be improved there shall be con-
structed a Portland cement concrete combined cUl'b and gutter. The back
of the curb shall be vertical, three (3) inches in height above the gutter line,
and seven (7) inches in depth below the gutter line. The top face shall be
constructed at right angles to the back of the curb and shall be one and
five -eighths (1-5/0) inches wide. The roaJ,way face of th~ curb sh<.'ll ue
in the form of a rc~verse vertical curve connecting the top face of the curb
vvith the upper surface of the gutter flag, with two (2) arcs of circles having
radii of four (4) inches. Tho'vvidth of curb from gutter line to back of curb
shall be eight (8) inches. Th<3 gutter flag shall be ten (10) inches in width
.
and eleven and one-half (11-1/2) inches in thickness at the pavement edge
and sh"ll ba lai-i with a rising incline toward the center of the roadway of
one -half (1/2) of an inch.
Construction joints shall be installed in said curb and gutter at
twenty (20) feet intervals. The joints shall be formed 'by steel templates,
one-eighth (1/1) inch in thickness, of a length equal to the width of the
combined curb and gutter, and with a depth of at least two (2) inches greater
than the depth of the curb and gutter. These templates shall ee left in
place until the concrete liaas set sufficiently to hold its shape but shall be
removed while the forms are still in place.
-4-
Concrete for the combined curb and gutter shall be composed of
one (1) part Portland cement, two (2) parts of fine aggregate and three
anJ one -half (3 -1 /Z) parts of coarse aggregate, \\ith only enough v.!ater
added to make a workable mix.
The ct)ment shall be of good grade PortIaau cement which rr1cets
the latest requirements of tile American Society for Testing Materials.
Mixing \~.rater shall be clean and shall be free of oil, acid or
injurious amounts of organic matter. (Jlkalies or other salts.
Fine aggregate shall consist oi sand having clean, hard, durable,
uncoated. grains free from deleterious suhstancds. C ne hundred percent
(100%) shall pass a one -fourth (i/ 4) inca screen and ninety-five percent
(95%) shall ue retained. on a lOJ mesh scre0n. Not more than tVJenty
percent (20(,70) shall pass a 50 mesh screen. It shall be well graded from
coarse to fine, and. shall not contain more than fiv3 percent (5%) DY v;icigilt
of clay or loam, none of which shall De in lumps.
~ihen the aggregate is mixed witll .f-'ortland cement ill tile propor-
dons of one (.i) part cement to two (2) parts fine aggregate by v'Joight
according to the standard method of making briquettes, th~ resulting

Immediately after the binder course mixture or surface course
mixture is placed it shall be compacted thoroughly and uniforrr~ly viith
a three -v.rheel roller. Where initial rolling causes undue displacement,

freshly laid bitumineus mixture except 'lflhen the laying of this course is
to be discontinued for an extended length of time.
The speed of the roller at all times shall be slow' enough to a,void
displacement of the bituminous mixture; if displacement occurs, it shall
be corrected at once by raking comd applying fresh bituminous mixture
',,/here required. To prevent adhesion of the bituminous mixture tQ the
roller the wheels shall be kept moistened, but an excess of water will
not be permitted.

Immediately after the initial rolling of the surface course a test
shall be made for smoothness, with a ten (10) foot straightedge, to locate
high a.nd low spots so that they may be altered \'vhile the mixture is still
fresh. Binder course shall also be straightedgeJ in the manner described
for the surface courSe. Rolling of the binder and surface course shall
be continued until all roller marks are eliminated and the bituminous
mixtur.J is thoroughly compacted..
In all places inaccessible to the rollt:rs, such as locations adjacent
to curbs, gutters. headers, manholes, e.nd sinliler structures, t,he
required comprel:lsion shall be secured with hot tampers.
Any bituminous mixture that becomes lOC,lse, broken, mixed with
foreign material or vv'hich is defective in finish or density or which d.oes
not comply in all other respects with the requirements shall be removed,
replaced v"ith suitable material and finished in accordance with these
specific ation5.
