SAT& AS SPEC IF ICATIONS NO.•;ZO
The Board. cQf Trustees of the Citv of Huntington Beac.h:-California,
do ordain as follows; %
I to ' That "the following Specif.icati.ons are hereby adopted. for the construction
of Willite Pavement in the City of Huntington Beach, and' all. S"treets or
Alleys'hereafter directed to be improved in accordance lirith Specifications
I3'o. 00 shall be constructed according to the provisions and re-
I
quirement,s of these Specifications.
2. PLANS, etc.
The work herein provided for is to be dor:e in accordance with the
plans, profiles-, and cross-sections on file in the office of the City
Engineer of the City'of Huntington Beach, and all the work shall during its
progress, and do its completion, donform to the lines .and levels which may,
>from'time to time, be given by said City Engineer.`
3, WORK.
tThe'work to be done is as follows:
1. To excavate or fill in the area upon which the pavement_ herein-
after provided for, is to be constructed, to such an extent and. in such a
manner as may be,.required. by the plans, profiles, cross-sections and
specifications.
2. To lay thereon the pavement as provided for Yiereinafter.
I
3. To furnish all the materials necessary to perform said work.
4. To do whatever else is required by these; specificationm.
4. SUB-GRADE.
The sub-grade shall be such distance below the finished surface
�r � of the pavement as is shown on the adopted cross-sections and plans.
5. GRADING.
Grading shall include all filling, the removal of all materials of
whatsoever nature that may be encountered in the preparation of the 'street, :

I '
I
I
II
and shall also include all trimming and shaping required to bring the surface
of the street to the required grade and cross-section as shown on the plans. . ! j
When mud or other soft material is encountered, it shall be taken out
and the space filled with good serviceable material, which .shall be thorough-
ly compacted by rolling, puddling or tamping. The Contractor, -however,
will not be required to excavate the mud or other soft material to a greater
depth than two feet below sub-grade.-
All filling shall be done with good, clean, serviceable material. `l
The embankments shall be carried up of full width in horizontal layers, not
II
to exceed one foot in thickness, and the teams shall be made to travel as
evenly as possible over the whole surf ace 'of each layer both gong and
coming. The forme_tion of well defined ruts is especially prohibited.
` Tvo materiel of a spongy nature shall be used for filling. The space over
I
which the fill is to be made shall be first cleared, of all brush, rubbish
or timber. 4
After the street hits been brought to sub -grade and cross-section,
the surface shall be thoroughly watered. and rolled with a roller sufficient-
ly heavy to make the surface hard and unyielding, and where practical the `
' I
street shall be cross-rolled as well as longitudinally. Depressions made
by rolling shall be levelled up with good material and again rolled. Such
portions of the street as cannot be properly compacted by rolling shall be
tamped solid.
The contre.ctor shall notify the City Engineer when a block or section
has been brought to sub-grade, when the latter will check the eleu6.tions of-
the same , and if the work is found to be in accordance with the specifications
. � I
I
and grades given, the Contractor shall proceed as hereinafter mentioned.
6, WILLITE PAVEMENT:
The pavement shall be that known as Willite and shall be Willite
Plastic Composition properly placed and consolidated. The ffillite Pavement _
shall be laid upon a grade prepared as hereinbefore described and shall be

shall be laid. in two courses; the lower course, or base, shall be two and
I
and one-half inches (2?") in thickness, and the upper course, or wearing
surface, shall be one and one-half--inches (1 ") in'thickness after

mixed.not less than forty-rive seconds for base and not less than sixty
1 seconds for wearing surface, or until every particle of sand, sand filler `
or stone dust and gravel or broken .stone is thoroughly coated-with e. thin
s '

-6- I
I
J
i
rr
Fahrenheit, and must be fine-grained and capable of producing a. compact
pavement.
15. LAYING PAVED.9ENT MATERIALS:
All materials used in the pavement, both for the base and top wearing
course, and single course pavement, shall conform to the percentage herein-
- above specified for preparing the Willite Plastic Composition. All contact
surface of curbs, manholes and all cold pavement joints shall be painted
j with hot asphalt cement before wearing surface is laid.. When preparing
VTillite base to. receive the top course of ffillite wearing surface, the surface
of the base shall be swept of all dust or rubbish, and asphalt paint binder
of the asphalt cement, herein specified under "Materials," shall be uniformly
I
! sprinkled over the entire surface of the base, either by a spraying machine
I
or brooms, and after the paint binder has been applied the street shall be j
barricaded until the wearing surface is laid. To prevent radiation, a
heavy duck tarpaulin shall cover the Willite material from the time it leaves
the mixing plant until it is deposited upon the work. The Willite Plastic ,
Composition, prepared as above specified, shall be brought to the work and i !
shall not be colder than two hundred and fifty (250) degrees Fahrenheitp nor
hotter than three hundred and twenty (320) degrees -Fahrenheitg when it
1 _
reaches the place of the improvement where it will be deposited.
i When the Willite material arrives at the job, it shall at once be
uniformly spread with hot shovels and hot rakes to such a depth that, after
p receiving its ultimate compression, each layer of the Willite-pavement will
I
be of a thickness not -less than that shown on cross-section adopted. for the
work. Rakes used for this purpose shall have strong teeth of a length
• I
i
sufficient to penetrate through the entire thickness of each layer of the
pavement. After spreading each layer of the pavement, it shall be thorough-
ly rolled by a steam or gasoline roller having a weight of not less than two
hundred and ten (210) potmda per linear inch width of tire. Diagonal or j
i
�. cross-rolling shall-be done wherever possible. All rolling shall be done i
in a manner to give a true, unif orm. surface to the finished pavement and
Id
until no further compression is shown under the wheels of the roller and
the rolling shall be carried on continually until the Willite pavement is
-7-
i
I
! so compressed. All places that are inaccessible to the roller must be
tamped with hot iron tampers. The resulting pavement must be shown
a close-grained, even and smooth surface9 true_ to grade and cross-section
and free from all hollows and inequalities.
16. TRAFFIC: I
u
` I
No traffic shall be allowed on the street until the pavement is �
- I
thoroughly Cooled and. set. All cold joints shall be painted with hot
asphaltic cement. - -
