immersion. The vibrator shall be of a size and weight to thoroughly
vibrate the entire concrete mass without damaging or misaligning the
forms and shall vibrate at a minimum frequency rate of 7,000 cycles
per minute. Forms shall be left in place for 24 hours or until the
concrete has sufficiently hardened, as determined by the Engineer,
so that they can be removed without injury to the curb. Upon removal
of the forms, the exposed faces of the curb shall be immediately rubbed
to a uniform surface. Rubbing shall be accomplished by competent and
skillful finishers. No plastering will be permitted.

two feet long. It shall be of such consistency that it will not run
in summer or chip out in winter.
(4) Weakened plane transverse joints shall be provided
every four feet on centers.
E. Forms.
(1) Forms shall be metal and held rigidly in place by
stakes or braces with top edges at true line and grade. Ends of adjoining
forms shall be flush. Wood forms will not be permitted.
(2) Division plates shall be 1/8-inch steel, as wide as
the depth of the slab and as long as the width of the walk.
(3) Forms and division plates shall be thoroughly cleaned
and oiled each time before they are used.
(4) Division plates shall be removed after the concrete
has hardened sufficiently to avoid breaking the edges of corners of
the slab.
F. Depositing concrete.
(1) The concrete shall be placed in one course to the
full depth of the slab.

when the temperature is, or is liable to be within 24 hours, below
35° F.
G. Finishing.
(1) The surface edges of each slab shall be rounded to
a radius of 1/4 of an inch.
(2) The surface of the walk shall be a broomed finish,
traverse to the walk.
H. Curing and protection.
(1) Immediately after final finishing, the sidewalk shall
be covered with waterproof paper or plastic sheets, which will be
maintained in place for at least three days, when the walk shall be
cleared and opened to traffic. (Instead of waterproofing paper or
plastic sheets, a curing agent approved by the Village Engineer may
be sprayed on the finished sidewalk. Use of calcium chloride will
not be permitted.)
(2) During sidewalk construction, all necessary safety
devices, such as barricades, lights and warning signs, shall be used
to protect the unfinished work and the public from injury.
(3) Walks marred by dripping water, tracks of animals
or persons, broken edges, or marred in any manner before the concrete
has set, due to insufficient protection, shall be renewed.
(4) All repairs of defective walks must be made promptly
and in a workmanlike manner. The work on the repairs of the surface
of the walk shall be so managed that the repaired surface shall not
be noticeable.
I. Restoration.
(1) All adjoining walks, lawns, driveways, and other property
are to be properly replaced in as good condition as at the beginning
of the work. Where a walk is constructed through a driveway, the area
adjacent to the walk shall be restored with the same material as in
the existing drive. Where the work is constructed through a lawn,
the area adjacent to the walk will be backfilled with topsoil and
seeded.
(2) Scraping of material onto adjoining property will
not be allowed except by the written consent of the owner. Refuse
material of the work must be immediately removed, lot by lot, upon
the completion of the work, and no material shall be left on any pavement

(1) When curbing is to be constructed on a freshly laid
bituminous surface, the curb may be laid only after the surface has
been cleaned.
(2) When curbing is to be constructed on a cured or aged
Portland cement concrete base, bituminous pavement or bituminous treated
base, the bed shall be thoroughly swept and cleaned by compressed
air. The surface shall be thoroughly dried and, immediately prior
to placing of the bituminous mixture, shall receive a tack coat of
either Section 702-21 or Section 702-30 of the NYSDOT Standard Specifications,
Construction and Materials, dated January 2, 1973. The rate of application

and size shown on the Standard Sheet by use of a self-propelled automatic
curber or curb machine or a paver with curbing attachments.
(2) The automatic curber or machine shall meet the following
requirements and shall be approved by the Engineer prior to its use:
(a)

to immediately cease their operations until such permit is procured.
In addition, having once unearthed any public or private utility,
such excavation will not be backfilled until inspected and approved
by the Village of Angola. Contractors, utilities, and others doing
so without permission of the Village of Angola will be required to
reopen the excavation for Village inspection and approval at no cost
to the Village.
