Be it resolved by the Bt%ard of Trustees of the City of
Newport Beach that the following [specifications, to be known as
Specifications T ?o. 40, for the construction of macadam pavement,
cement concrete gutters, culverts and appurtenances, catch basins,
drains, guard fences, grading, concrete steps and concrete retain-
ing walls, in the City of Newport Beach, be and the_same are hereby
adopted.
WORK TO BE DONE
Under these specifications the Contractor will be re-
quir ed:
1. To excavate or fill in to such an extent and in such a
manner as may be required by the plans, profiles and cross - sections,
and these specifications, the area upon which the improvement here-
inafter provided for is to be constructed.
2. To furnish all materials as hereinafter provided for and
required for the construction and completion of the improvement
in accordance with the plans and specifications, and all labor, tools
and equipment necessary for the performance of said work.
3. To grade and construct macadam pavement, cement concrete
gutters, culverts and appurtenances, catch basins, drains, retaining
walls, guard fences, etc. as hereinafter specified.
GRADING
Grading shall include all filling, the removal of all
earth, sand, stone or all other material of wh4tever nature it may
be that may be encountered in preparing the road, and shall also
include all trimming and shaping required'to bring the surface of
the road to grade and cross - section. when mud or other soft
material is encountered, it shall be taken out and the space filled
with good earth, sand or gravel, which, if it is earth or gravel,
shall be rolled until the surface of the foundation ceases to creep
in front of the roller. The Contractor, however, will not be re-
quired in such cases to excavate mud or other soft material to a
depth greater than two feet below the sub - grade.
All filling shall be done with good sound earth, gravel
or sand. ^1henever a fill is to be made of earth or gravel, the
embankment shall be brought up in layers not exceeding six inches
in depth, and each layer thoroughly dampened and rolled with a
roller weighing not less than 200 pounds per lineal inch width of
tire, until it is firmly compacted. Then the fill is made with
sand, it shall be brought up to grade and thoroughly dampened end
compacted.
No material of a perishable, spongy, or otherwise in-
proper nature shall be used in filling. The space over whi. ^.h =ille
are to be made shall first be cleared of all brush, timber, trz�sh
or other debris unfit for foundation.

i. ±
During the process of grading, the street shall be
r:aintaincd in a reasonably good condition for traffic, care being
'.akin to remove the surplus material as evenly as possible over
the entire surf,�ce of the street.
The street sh ^.11 be plowed up not to exceed one mile in
-AOL length in �,.dvance of the laying of the pavement. The Contractor
shall at all times maintain proper drainage on the street.
The width of the street to be graded shall conform to
the plans, profiles and cross - sections.
After a section of street hes been graded, as heroin
specified, the surface shall be thoroughly drenched with water,
and when sufficiently dry, shall be rolled with a roller weighing
not less than 400 pounds to the lineal inch width of tire until
the surface is unyielding. Depressions made by rolling shall be
levelled up with good earth and again rolled. Such portions of
the street as cannot be reached by the roller, and all placed
excavated below sub -grade and refilled, and all pipe trenches and
other places that cannot be properly compacted by the roller,.shall
be tamped solid, and in cases of wet weather, or soft or muddy
ground making use of the roller unsafe or impracticable, the
rolling shall not be undertaken until the ground has become suffi-
ciently dry. If the sub -grade consists of sand, the rolling there-
of will not be required but it shall be compacted by wetting down
thoroughly and smoothed to conform to cross - section.
The Contractor shall notify the Engineer when a section
has been brought to sub - grade, when the latter will check the
elevations of the same, and if the work is found to be in accord-
ance with the specifications and grades given, the Contractor shall
proceed as hereinafter mentioned.
MATERIALS.
All materials for macadam pavement including stone
screenings, crushed rock and asphaltic oil for all purposes shall
conform to the following specifications:

30 and 33 to the minute, shall constitute 'a test. Only the per-
centage of material worn off which will pass through a 1/16 inch
mesh sieve shall be considered in determining the amount of wear.
The wear shall be expressed by a coefficient known as
the Coefficient of Tear, -hick coefficient shall be obtained by
the formula C = 400 divided by W, where C equals the coefficient
required and W the weight in grams of the detritus under 1/16 inch
in size per kilogram of rock used.
The rock used in the tests shall be furnished by the
Contractor and shall be delivered by him at the testing machine
when required by the Engineer.
ASPHALTIC OIL
The asphaltic oil used under these specifications shall
be made from an asphaltic base crude oil -hich, in its natural
state contains not less than seventy -five (75) per cent of eighty
(80) penetration asphalt, which must not have been injured by over-
heating and which must not be obtained by adding solid asphalt to
lighter oils or distillates.
The asphaltic oil shall be produced and distilled for
road purposes only, and refinery residuums, which are the by-
products from the refining of crudes for gasolines, distillates,
kerosenes and lubricating oils, will not be permitt#d under these
specifications.
During the refining process the oil shall not be heated
to a temperature above 5500 Fahrenheit.
TEMPERATURE
All oil must be delivered at the point required for
application at a temperature of not less than 2500 Fahrenheit, nor
more than 400° Fahrenheit.
• MEASUREMENTS

From the measured volume of oil received at any tem-
perature above 60° Fahrenheit, an amount equivalent to 3/BDth of
11% for every 100 above said 600 Fahrenheit shall be subtracted as
the correction for expansion by heat. For the purpose of measuring
oil a temperature of 60° Fahrenheit shall be deemed normal tem-
perature.

J
•
WATER AND SEDIMENT
It shall contain not more than 1/2 of 1?% by volume of
water, and not more than ljo by volume of sediment. Deduction will.
be made for water and sediment in exact proportion to- the per-
centage of water and sediment found therein.
ASPHALT
After being freed from water and sediment., the asphaltic
oil shall contain not less: than000o nor more than 95 0 of asphalt,
having a temperature of 770 Fe-:ir&nheit, a penetration of 800,
District of Columbia Standz.rd.
The percentage of asphalt shall be determined by heating
fifty (50) grams of said asphaltic oil or residuum in an evapo-
rating oven at a temperature of 565 degrees Fahrenheit, until it
has reached the proper consistency when the weight of residue shall
be determined and the per cent calculated. The time required to
reduce the oil to the penetration of 0.80 of a centimeter shall be
less than 165 minutes.
VOLATILITY
The oil shall not lose in excess of two (2) per cent of
vplatile matter when heated from a temperature of 770 Fahrenheit
tg 2260 Fahrenheit and maintained at 2200 Fahrenheit for fifteen
(15) minutes. The time required for heating from 770 F to 2200 F
shall be one (1) hour.

fifty (50) seconds above specified.
TANK TRUCKS.
All tank trucks used for the delivery of this oil must
first be submitted to the Engineer who will gauge and stamp upon
said tanks the capacity in gallons, and no figure of capacity will
be accepted other than the official rating given by said Engineer.
MACADAM PAVEMENT
Upon the sub -grade prepared as specified herein shall be
laid a base course or layer of crushed rock consisting of a mixture
of'not less than fifty (50) per cent nor more than seventy (70)
per cent, by weight, of No. 1 Crushed Rock, and not less than
thirty (30) per cent nor more than fifty (50) per cent, by we.,ght;
of No. 2 Crushed Rock, of tha quality an�cli.fi.ecl iii these speci-'ii•-
catiq'Is� and which shall be spread ur,if`oxml•9 tc the required
width of the pavement and to f rch thicknees , a ..a:' -i, when fully
compressed in the manner here= naftsr. spsci,:ie'- will have a +.h:ek•-
ness of'not less than three and o;:a - -half %3 l,%„) inches.
- 4 -
Spreading of the crushed rook may be done by hand o by
approved mechanical spreaders, but whatever the method, care must
be taken to insure that the thickness is uniform throughout its
length and width, and that the various sized fragments of the
crushed rock specified are well mixed and in no`'case segregated.
'When the spreading is done by hand the crushed rock shall be
deposited on a platform and from there shoveled into place on the
AWk sub- grade.
Wherever the macadam does not terminate against a curb,
gutter or another pavement, shoulders of firm earth, disintegrated
granite or gravel of a depth equal to the thickness of the pave-
ment shall be left or made at such termination for the pavement
to abut against.
The rolling, mechanical locking, bonding, seating or
bedding shall be done by properly operated standard 3 -wheel
macadam rollers having a linear inch weight on the driving wheels
of not less than 400 pounds. Rolling shall be commenced at the
edge of the spread layer of crushed rock , the roller following
the same track until the edge of the course is fastened against
any side movement from further rolling. The edge being fastened,
thie rolling shall be continued by six inch (611) set -ins, or laps,
until the center of the spread course is reached, and then the
roller is to be started at the other edge and In a like manner
worked to the center of the course. The roller must at all times
be operated on lines parallel to the center line of the pavement,
and no material variation from such lines shall be made. Changes
in the direction of movement of the roller must not be conterminous
and the roller must not be allowed to stand on the layer of crushed
rock until same has been properly consolidated.
Rolling, as described above, must be continued until the
crushed rock is bedded, bonded and mechanically locked, and until
no movement of the rock fragments can be seen as the roller passes
over the layer of crushed rock. As an aid in consolidating the
crushed rock, watering of the layer may be done, but the amount
of water used must not be enough to wet the sub - grade. All
depressions in the layer of crushed rock that develop during the
rolling must be promptly filled with No. 2 Crushed Rock, and re=
rolled.
After the layer of crushed rock has been properly rolled,
bedded, bonded and so mechanically locked as to meet with the
approval of the Engineer, the voids remaining in the layer shall be
filled with No. 4 Stone Screenings, the filling to be done by
spreading or drifting a light application of No. 4 stone screen-
ings over the surface of the layer, care being taken to have the
filler thrown in lines parallel to the center line of the pavement,
and the fine stone screenings worked down into the layer by rolling
and watering. The spreading of the filler and the rolling and
watering must be continued until all voids are filled to the sur-
face of the layer of crushed rock, and until the layer will sustain
and not show wheel or tire tracks from a motor truck carrying a
load and having a compression of 900 pounds per inch width of tire.
After this course, or layer, of crushed rock has been
rolled and filled as above specified, and the surface having dr.ed,
it shall be swept by the use of street hand broors to r ,io;c al-
loose filler from the surface and in the upper n:.e- gi..artc -:r (1/':0
inch of the layer. The surface shall then u . .�:_,;; �y wa c re n.nd
n not less than thirty (30) minutes, nor !.,or ;nan one
c.sphaitic oil, as specified in these specificaticns, Ehall be
applied by a poTer pressure spraying machine appro.�ec: by the
.;ng;neer, at the rate of one -half (1/2) gallon per square yard
c-f surface covered, and at a temperature of not less than two
hundred fifty (250) nor more than four hundred (400) degrees
Fahrenheit. Immediately after oil has been applied, No. 3 Crushed
'Rock, as specified in these specifications, shall be spread o,.rer
iWN ; a.
tii° oiled surface in a thin, uniform layer, in sufficient quan-
tity to just cover the oil. The surface shall then be immediate-
ly broomed, watered and rolled to bind the No. 3 crushed rock,
and form a true surface. Then a second coating of asphaltic oil
as above specified shall be uniformly applied at the rate of not
less than one - fourth (1/4) nor more than one -half (1/2) of a
gallon per square yard of surface covered.. A light coating of
• No. 4 stone screenings shall then be uniformly spread or drifted,
over the surface in sufficient quantities to absorb all surplus
oil and produce a uniform surface with no oil exposed, and.no
patches or excess crushed rock or stone screenings.
The pavement shall then be broomed, watered and rolled
until it becomes smooth, true to grade and cross- section, and free
from all bunches, hollows and irregularities.
The base course of crushed rock above mentioned shall
not be laid for a greater distance than one - fourth (1/4) mile
ahead of the first application of oil, it being the intent of
these specifications to keep the work finished as closely as
possible, and not to unduly expose the loose crushed rock to in-
jury or damage from travel, dust or storm water.
Should it become necessary,to re -heat the asphaltic oil
to comply with the requirements of these specifications, it shall
be done at the expense of the Contractor, by the use of hot air
or superheated steam coils. In no case shall live steam or water
be injected into or allowed to enter the asphaltic oil after it
has been received by the Contractor.
No asphaltic oil shall be applied until the surface
which is to receive it is completed in accordance with these
specifications and satisfactory to the Engineer. At least twenty -
four (24) hours shall elapse between any two applications of
asphaltic oil over the sane area. In the process of oiling, oil
must not be allowed to fall on any concrete headwalls, curbs,
gutters, walks, or private driveways. All oil tanks and measure-
ments of oil shall be as specified in these specifications.
The Contractor shall not use, or permit the use of this
pavement by vehicles until he has received authorization to do so
from the Engineer..
