2.1.6 Roadway Pavement
The type of pavement usually is determined by analysis of the volume and composition of
traffic, the soil conditions, the availability of materials, the initial cost and the estimated cost
of maintenance.
Criteria and procedures for selecting the type of pavement and the structural design of the
various surfacing courses are discussed in the Department's pavement design manuals.
2.1.6.1 Alternative Roadway Paving Treatments
Alternative paving treatments, such as patterned pavement and architectural pavers
meeting FDOT Specifications, may be used for enhancing aesthetics and appearance
when requested by a local community, and when the conditions and restrictions provided in
this section are met. Patterned pavement treatments are covered under Section 523 of the
FDOT Specifications and are surface markings applied either as an overlay to the
pavement surface or imprinted in the pavement surface. Architectural pavers are covered
under Section 526 of the FDOT Specifications and consist of brick pavers or concrete
pavers placed on specially prepared bedding material.
These alternative pavement treatments are purely aesthetic treatments and are not
considered to be traffic control devices. Use of either of these treatments is highly restricted
as stated below. Even when all conditions and restrictions are met, any decision to use
these treatments should consider that there may be potential adverse impacts to the
traveling public as well as potential long term maintenance problems. Architectural pavers
have been found to create significant ride-ability problems even on low speed roadways.
Therefore, architectural pavers are prohibited within the traveled way on the State Highway
System. Properly installed patterned pavement treatments do not significantly affect ride-
ability; however, their use is also restricted since they are not likely to sustain their friction
and wear characteristics for the full life of typical roadway pavement.
These paving treatments involve additional construction and maintenance costs not
associated with typical roadway pavement. Therefore, appropriate agreements with the
local maintaining agency must be obtained. The local maintaining agency must provide the �
additional funding for construction and assume responsibility for regular inspection and
maintenance of the pavement treatment. In cases where existing alternative pavement is
being removed as part of a Department project, replacement of such pavement must �
adhere to the requirements in this section regardless of the circumstances of the original
installation and maintenance. Maintenance agreements for installations within the traveled
way on the State Highway System must include the provisions outlined in Section 2.1.6.2 �
for the duration of the installation.

The following restrictions apply:
Architectural Pavers:
� 1. Must not be used on the traveled way of the State Highway System.
2. May be used on local side streets (with a design speed of 35 mph or less), non-
traffic medians and islands, curb extensions, sidewalks, borders, and other
areas not subject to vehicle traffic.
3. Meet ADA requirements in areas subject to pedestrian traffic. See Public
Ri_qhts of Way Accessibilitv Guidelines (PROWAG) R301.5 and R301.7 and
Americans with Disabilities Act Accessibility Guidelines (ADAAG) 302 and
3Q3 for surface requirements.
Patterned Pavement:
1. Use on the traveled way of the State Highway System is restricted to areas within
marked pedestrian crosswalks where the design speed is 45 mph or less;
� however, patterned pavement cannot be used on pedestrian crosswalks across
limited access roadway ramps. Use on pedestrian crosswalks with heavy truck
traffic turning movements (>_ 10% trucks) should be avoided.
� 2. The pavement to which the treatment is applied must be of the same pavement
type as, and continuous with, the adjoining pavement. For example, replacing
flexible pavement with rigid patterned pavement within the limits of a crosswalk
where the abutting pavement is to remain flexible pavement will likely result in
pavement joint problems and adverse impacts to rideability. This type treatment
is therefore not permitted. Replacing flexible pavement with rigid pavement for
an entire intersection including crosswalks may be permitted with a Technical
Special Provision submitted to the State Roadway Design Engineer for approval.
3. The initial treatment cannot be applied to any State Highway whose asphalt
pavement surFace is older than 5 years.
4. May be used in areas not subject to vehicte traffic such as median islands, curb
extensions, sidewalks, and landscaping borders.
� 5. Meet ADA requirements in areas subject to pedestrian traffic. See PROWAG
R309.5 and R301.7 and ADAAG 302 and 303 for surFace requirements.
I When architectural pavers are used, identify the location, type, pattern, shape and color in
the plans. In addition, project specific details and requirements for edge restraints,
bedding material thickness, and base and sub-base materials and thicknesses, as
� appropriate, must be developed and included in the plans, which must be signed and
sealed by a licensed Florida Professional Engineer.

Plans Preparation Manual, Volume 1 January 1, 2016
When patterned pavement treatments are used, identify the location, patterned type (
(brick, stone, etc.), and surface color in the plans. Because local agencies must fund
and maintain these treatments, product brands, colors and patterns may be specified in
the plans as long as the brand is listed on the APL at the time of use.
Design Variations to any of the requirements in this Section must be approved by the �
District Design Engineer.
2.1.6.2 Maintenance Memorandum of Agreement
Requirements for Patterned Pavement
Prior to the installation of patterned pavement crosswalks in intersections on the State
Highway System, a Maintenance Memorandum of Agreement must be entered into with (
the local government agency requesting this aesthetic enhancement to the project. This
agreement must be filed with the District Maintenance Office. This Agreement requires �
the local government agency to acknowledge that the installation and maintenance of
patterned pavement is the total responsibility of the local agency, including contracting
for friction testing with a qualified firm.
"Maintenance" of all patterned pavement crosswalks in these Agreements must be �
defined, as a minimum, to include its frictional characteristics and integrity as follows:
1. Evaluate a11 lanes of each patterned crosswalk for surface friction within 60 days of I
project acceptance by the Department. Conduct the friction test using either a
locked wheel tester in accordance with FM 5-592 (Florida Test Method for Friction
Measuring Protocol for Patterned Pavements) or a Dynamic Friction Tester in
accordance with ASTM E1911. FM 5-592 can be accessed at the following link:
http://materials,dot.state.fl.us/smo/administration/resources/iibrarvlpublications/fis
tm/Methods/fm5-592. pdf
The initial friction resistance must be at least 35 obtained at 40 mph with a ribbed I
tire test (FN40R) or equivalent. Failure to achieve this minimum resistance will
require all deficient crosswalk areas to be removed to their full extent (lane-by-lane)
and replaced with the same product installed initially. If the Department determines
that more than 50% of the lanes in the intersection require replacement, the entire
intersection installation may be reconstructed with a different product on the
Approved Products List (APL) or replaced with conventional pavement.
2. Approximately one year after project acceptance and every two years thereafter
and for the life of the adjacent pavement, only the outside traffic lane areas of
each patterned crosswalk must be tested for friction resistance in accordance �
Design Geometrics and Criteria 2-17
( Topic #625-000-007
Plans Preparation Manual, Volume 1 January 1, 2016
� with ASTM E274 or ASTM E1911. Friction resistance must, at a minimum, have
a FN40R value of 35 (or equivalent).
� 3. Send the results of all friction tests to the District's Warranty Coordinator with a
cover letter either certifying that the crosswalks comply with the minimum friction
criteria, or stating what remedial action will be taken to restore the friction.
� 4. Failure to achieve the minimum resistance requires all lanes of the crosswalk to
be friction tested to determine the extent of the deficiency. All deficient areas
� must be removed to their full extent (lane-by-lane) and replaced with the same
product installed initially. If the Department determines that more than 50% of
the lanes in the intersection require replacement, the entire intersection
installation may be reconstructed with a different product on the APL or replaced
with conventional pavement.
5. When remedial action is required in accordance with the above requirements, the
� local agency must complete all necessary repairs at its own expense within 90
days of the date when the deficiency was identified. No more than two full depth
� patterned pavement repairs can be made to an area without first resurfacing the
underlying pavement to 1" minimum depth.
6. The Department will not be responsible for replacing the treatment following any
construction activities in the vicinity of the treatment.
7. Should the local agency fail to satisfactorily perform any required remedial work
in accordance with this agreement, the Department reserves the right to replace
the patterned pavement with conventional pavement (matching the adjacent
pavement) and bill the local agency for this cost.
