3.03 WARRANTY REQUIREMENTS
A. Each warranty period is for 6 yr. and starts the day after written acceptance.
B. The marking warrantor is responsible for meeting the Performance Requirements for the
duration of the warranty period.
C. During the warranty period, the City will conduct periodic visual performance evaluations of
the pavement markings. For retroreflectivity the City will use Tex-828-B, “Determining
Functional Characteristics of Pavement Markings.” The warrantor may be present during these
evaluations. For areas, which, in the opinion of the City have a questionable visual evaluation,
the warrantor may replace the pavement markings or may conduct a performance evaluation for
the performance requirement in question, conduct retroreflectivity evaluations using either
portable or mobile retroreflectometer unless otherwise indicated in the Contract Documents.
The warrantor is responsible for traffic control when conducting performance evaluations.
D. The warrantor will replace pavement markings that fail to meet the color, retroreflectivity, or
durability performance requirements during the warranty period, and must replace the pavement
markings that fail to meet the performance requirements within 30 days of notification.
E. All replacement pavement markings must meet the materials and performance requirements of
this specification.
F. The end of the warranty period does not relieve the warrantor from the performance deficiencies
requiring corrective action identified during the warranty period.
G. The City may exclude pavement markings from the replacement provisions of the warranty
period, provided the City determines that the failure is a result of outside causes rather than
defective material. Examples of outside causes are extreme wear at intersections, damage by
snow or ice removal, and premature pavement failure.
H. Provide a contact person, address and telephone number for notification of needed pavement
markings replacement.
I. Each class of raised pavement marker shall be from the same manufacturer.
J. The pavement markers shall be placed in proper alignment with the guides. The deviation rate
in alignment shall not exceed one (1) inch per 200 feet of roadway. The maximum deviation
shall not exceed two (2) inches nor shall any deviation be abrupt.
K. Unless otherwise noted, adhesives shall be applied in accordance with the manufacturer’s
recommendations.
L. The roadway to be marked will remain open to traffic and the Contractor shall provide all
necessary warning and barricading to insure the safety of the workmen and traffic, and the
Contractor must insure proper maintenance of all warning and barricading devices at all times.
Construction, signing, channelizing devices, and markings shall conform to the current Texas
Manual on Uniform Traffic Control Devices (TMUTCD) at all times.
M. A minimum of one lane in each direction shall remain open to through traffic at all times.
N. The Contractor shall conduct the installation so as to minimize the duration of restricted traffic
movements.
O. The Contractor shall apply pavement markers and markings during off-peak traffic hours (9:00
