1.
Description
This specification is for furnishing a system
designed for providing pavement markings directed at pedestrian and bike path
delineation. The applied markings will have significant skid resistant features
not typically associated with thermoplastic systems, will be durable, oil and
grease impervious, and provide immediate and continuing retroreflectivity. This
unique marking system can be adhered to asphalt and portland cement concrete
pavements by means of heat fusion, and without the need and requirement for
sealers and primers.
2. Materials - General
2.1 The preformed retroreflective marking material shall
consist of a resilient polymer thermoplastic (alkyd, no hydrocarbon) with
uniformly distributed glass beads and abrasives throughout its entire cross
section. Preformed retroreflective markings shall be available conforming to
the current edition of the Manual on Uniform Traffic Control Devices for
Streets and Highways as issued by the U.S. Department of Transportation Federal
Highway Administration.
2.2
The
preformed marking materials shall not be brittle and will be sufficiently
cohesive and flexible at temperatures exceeding 50ºF.
2.3 The preformed marking materials shall be fusible to
asphalt and portland cement concrete pavements by means of the normal heat of a
propane type torch. Adhesives, primers, or sealers are not necessary prior to
the preformed markings application on asphalt and portland cement concrete
pavements.
2.4 The preformed marking materials shall conform to
pavement contours, breaks, and faults through the action of traffic at normal
pavement temperatures. The markings shall have resealing characteristics and be
capable of fusing to itself and previously applied hydrocarbon and / or alkyd
thermoplastic pavement markings.
2.6 The preformed marking materials shall be capable and
ready to open to traffic 15 minutes after application.
2.7 The preformed marking materials shall be suitable
for use for one year after the date of receipt when stored in accordance with
the manufacturer's recommendations.
3. Manufacturing Control and ISO Certification: The manufacturer must be ISO
9001:2008 certified and provide proof of current certification. The scope of
the certification shall include manufacture of preformed thermoplastic pavement
marking material.
4. Classification: The preformed marking
materials shall be highly durable retroreflective pliant polymer thermoplastic
materials designed for transverse, legend, and symbol markings. This system is
designed for and subjected to high urban traffic volumes and particularly
severe wear conditions including winterized maintenance practices employed by
various regions of the US DOT market.
5. Requirements
5.1 Composition: The preformed marking materials shall consist
of a homogeneous mixture of high quality polymeric thermoplastic binders,
lead-free pigments, fillers, and intermix glass throughout the entire
composition. The thermoplastic material must conform to AASHTO designation M249
with the exception of the relevant differences due to the material being
preformed, and identified herein.
06.22.10 HT SO 90 SA
5.1.1 Intermix Glass: The
preformed retroreflective material shall contain a minimum of 30% glass,
comprised of approximately 50% glass spheres conforming to AASHTO M247 Type 1
and 50% abrasives uniformly distributed throughout the material. Glass spheres
shall have a minimum of 80% true spheres overall.
5.1.2 Top Glass: To provide
uniform retroreflectivity and skid resistance, a proprietary glass bead and
abrasive combination shall be factory preapplied at a uniform rate. The glass
beads shall have a minimum of 80% true spheres overall.
5.2. Retroreflectivity: The
preformed marking materials shall upon application exhibit uniform adequate
nighttime visibility (retroreflectivity). The applied markings shall have an
average minimum retroreflectivity of 250 mcd/lx/m2 for white
markings and 150 mcd/lx/m2 for yellow markings.
Note: The initial retroreflectivity
values assume proper application. For optimum retroreflectivity, beads must be
embedded, upon application, 50% - 60% into the preformed thermoplastic.
5.3 Color Characteristics: Preformed
marking materials without preapplied top glass beads shall meet the following:
White: Daytime luminance factor
(cap Y) of 80% minimum.
Yellow: Daytime luminance factor
(cap Y) of 45% minimum.
The daytime luminance factor shall
not change significantly when the preformed retroreflective thermoplastic is
properly applied to the roadway surface.
For highway use, the white markings
shall contain a minimum of 10% by weight of titanium dioxide pigment. Yellow
color shall reasonably match color chip Number 13538 of Federal Standard number
595 and be lead free.
5.4 Skid Resistance: The surface
of the preformed marking materials shall provide a postapplied minimum skid
resistance value of at least 60 BPN when tested according to ASTM E 303.
5.5 Thickness: The
thickness of the supplied material shall have a minimum average thickness of
0.090 in. (2.29 mm) (expressed as 90 mils).
5.6 Flexibility: The
preformed marking materials shall have flexibility at 50ºF such that when a 1
in. by 6 in. sample is bent through an arc of 90º at a uniform rate in 10
seconds (9º per second) over a 1 in. mandrel, no cracking occurs in the test
sample. The sample must be conditioned prior to testing at 50ºF ±2 for a
minimum of four hours. At least two specimens tested must meet the flexibility
requirements at 50ºF for a passing result.
5.7 Bond Strength: The
preformed marking materials must have superior bonding strength of at least 300
psi on portland cement concrete when tested according to ASTM D 4796, except
that a 2 in. by 2 in. specimen shall be placed on a preheated brick (15 minutes
at 425ºF) and then placed in a 425ºF oven for 15 minutes.
5.8 Tensile Strength and
Elongation: The preformed marking materials shall have a minimum tensile
strength of 150 lb. per square inch of cross section when tested according to
ASTM D 638, except that a sample 1 in. wide by 6 in. long shall be tested at a
temperature between 70ºF and 80ºF using a jaw speed of 10 in./min. The sample
shall have a maximum elongation of 20% at break when tested by this method.
5.9 Low Temperature Cracking
(Stress) Resistance for Extended Period: The preformed marking
materials shall be tested according to AASHTO T250 section 7 with section 7.2.3
modified for extended cold temperature (-9.4ºC ±2 (15ºF ±3)) exposure period of
72 hours. Any cracking shall constitute failure of the material for portland
cement concrete road surfaces.
06.22.10 HT SO 90 SA
06.22.10
5.10 Environmental Resistance: The applied
preformed marking materials shall be resistant to deterioration due to exposure
to sunlight, water, oil, diesel fuels, gasoline, pavement oil content, salt,
and adverse weather conditions.
5.11 Effective Performance Life: When
properly applied, in accordance with manufacturer's instructions, the preformed
marking materials shall be neat and durable. The markings shall remain skid
resistant and show no fading, lifting, shrinkage, tearing, roll back, or other
signs of poor adhesion.
6. Packaging: The
flexible preformed marking materials, for use as transverse or bike symbols as
well as legends, shall be available in flat form material up to a maximum of 2
ft. width by 4 ft. length. The material shall be packed in suitable
shrink-wrapped cartons clearly labeled for ease of identifying the contents.
Packaging shall not use plastic liners within to separate material from itself.
Product packaging shall identify part number and mil thickness.
7. Material Replacement Provisions:
Any
properly applied preformed marking materials that shall smear or soften
independent of pavement movement or condition within a period of one year from
date of application shall be replaced by the supplier.
8. Installation: The
preformed marking materials shall be applied in accordance with the
manufacturer's recommendations on clean and dry surfaces. New portland cement
concrete surfaces must be sandblasted to entirely remove curing compound.
Marking configuration shall be in accordance with the "Manual on Uniform
Traffic Control Devices" where applicable.
8.1 New Surfaces: Markings
specified for newly paved asphalt road
surfaces shall be capable of being
applied as the original permanent marking on the day the surface is paved.
8.2 Fusion: The
preformed marking materials shall be fusible to the pavement by means of a
propane torch recommended by the manufacturer.
9. Technical Services: The
supplier shall provide technical services as may be required.
10. Performance: The preformed marking material
shall meet state specifications and be approved for use by the appropriate
state agency
