ARTICLE V. SCOPE OF WORK
CONTRACTOR shall accomplish the following:
The contractor shall furnish all labor, material, and equipment necessary to perform all operations for the
application of an asphalt rejuvenating agent to asphaltic surfaces at various locations. All Traffic Control shall
conform to the Texas Manual on uniform Traffic Control Devices in accordance with the City of Lubbock
Public Works Engineering Standard Paving Specifications, Section 10.1, BARRICADES. A map of streets
selected for application is hereto attached and incorporated by reference.
The contractor shall be responsible for sweeping and cleaning of the streets prior to, and after treatment when
required. Prior to treatment, the street will be cleaned of all debris (dirt, leaves, foreign materials, etc.) This
work shall be accomplished by brooming, power blowing, or other approved methods. All sand used during the
treatment must be removed no later than 48 hours after treatment of the street. This shall be accomplished by
mechanical sweeping. All turnouts, cul-de-sacs, etc. must be cleaned of any material to the satisfaction of the
Street Superintendent. If the cleanup process falls behind or the cleanup is not satisfactory to the Street
Superintendent the application process will be halted until the sweeping crew has caught up, or until the street
and surrounding right of way has been cleaned. Street sweeping and clean up shall be included in the price per
square yard for the asphalt -rejuvenating agent.
The asphalt -rejuvenating agent shall be applied by a distributor truck at the temperature recommended
by the manufacturer and at the pressure required for the proper distribution. The emulsion shall be applied so
that uniform distribution is obtained at all points of the areas treated. Areas inadvertently missed shall receive
additional treatment. Application of asphalt rejuvenating agent shall be on one-half width of the pavement at a
time. When the second half of the surface is treated, the distributor nozzle nearest the center of the road shall
overlap the previous application by at least one-half the width of the nozzle spray. In any event the centerline
construction joint of the pavement shall be treated in both application passes of the distributor truck. The
asphalt -rejuvenating agent shall be blended with water at the rate of two (2) parts rejuvenating agent to one (1)
part water, by volume or as specified by the manufacturer. The combined mixture of asphalt rejuvenating agent
and water shall he spread at the rate of 0.05 to 0.10 gallons per square yard, or as approved by the Street
Superintendent following field testing. After the street has been treated, the area within one foot of the curb line
on both sides of the road shall receive an additional treatment of the asphalt rejuvenating agent. The treatment
shall be uniformly applied by a method acceptable to the Street Superintendent. After the rejuvenating agent has
penetrated the surface, a coating of dry sand shall be applied to the surface to protect the traveling public.
The asphalt -rejuvenating agent shall not be placed when the ambient temperature is below 40 degrees F as
determined by the National Weather Service continuous broadcast, 748-1071 selection 2. The asphalt -
rejuvenating agent shall be applied only when the existing surface to be treated is thoroughly dry and when it is
not threatening to rain.

sequence of work, and methods of providing for the safe passage of traffic before it is placed into
operation. If at any time during construction the approved plan does not accomplish the intended purpose,
due to weather or other conditions affecting the safe handling of traffic, the Contractor shall immediately
make necessary changes therein to correct the unsatisfactory conditions.
At night or otherwise, all equipment not in use shall be stored in such a manner and at such locations as not

direction of the Street Superintendent, except that the utility companies will move their equipment at no
cost to the Contractor. The Contractor will receive no compensation for delay caused by the Utility
Companies in relocating or removing their equipment.

approval of materials, mix designs, adequacy of procedures, etc. The results of such testing shall be
evaluated and final approval given by the Street Superintendent.
A. CONCRETE MATERIALS
Before Concrete materials can be used on any street, a current mix design (not older than 30 days) with
test reports will be submitted to the Street Superintendent for approval. During the construction period,
concrete tests that fail will require the location to be cored at the contractor's expense. If the concrete
cores fail, the concrete work will be removed and replaced at no additional cost to the City of Lubbock.
B. HOT MIX
The Contractor, or supplier of such materials, shall submit a mix design to the City Pavement

concerning the proposed award to the subcontractor, which statement shall contain such information as the
Owner may require.
The Contractor shall be as fully responsible to the Owner for the acts and omissions of his subcontractors,
and of persons either directly or indirectly employed by them, as he is for the acts and omissions of
persons directly employed by him.
The Contractor shall cause appropriate provisions to be inserted in all subcontracts relative to the work to
bind subcontractors to the Contractor by the terms of the General Conditions and other contract documents
insofar as applicable to the work of subcontractors and to give the Contractor the same power as regard

damage by his operations to any pipeline or underground installation.
It is the Contractor's responsibility, during the period of street construction, to insure that all utility cuts in
the limits of street construction have been properly backfilled, compacted, and the top 6" inches backfilled
with 2 -sack flowable fill. It is not the intent to require the Contractor to provide for the utility cut repair
but for the individual utility company making the cut to provide their own repairs.

Superintendent's option, to repair the cut with 2 -sack flowable fill at the unit price bid.
12. PARTIAL PAYMENTS

any damage to other work resulting therefrom, which shall appear within a period of one (1) year from date
of final acceptance of the project. The Owner or the Owner's Representative shall give notice of observed
defects with reasonable promptness.
14. LABOR

Labor, and must not pay less than the rate legally prescribed or as set forth herein, whichever is higher.
Payment for time worked over forty -hours per week shall be made at one and one-half (1-1/2) times the
above prevailing rates. Payment for time worked on legal holidays shall be paid at one and one-half (1-1/2)
times the regular goveming per diem wage rates.

day, under the emergency exceptions to House Bill No. 115 of the 44th Legislature invoked by HCR No.
201 of the 47th Legislature shall be paid on the basis of eight (8) hours constituting a day's work.
