**3.1 PREPARATION**

**\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\***

**NEWLY LAID FLEXIBLE AND RIGID PAVEMENTS REQUIRE AGING PRIOR TO
PAINTING IN ORDER TO OBTAIN SATISFACTORY PAINT PERFORMANCE. IF
PRACTICABLE, ALL NEW PAVEMENT SURFACES SHOULD BE AT LEAST 30 DAYS OLD
BEFORE APPLICATION OF MARKING MATERIALS. WHEN EARLIER APPLICATION OF
PAINT IS NECESSARY BECAUSE OF OPERATIONS REQUIREMENTS, THE MAXIMUM
PERIOD PRACTICABLE SHOULD BE SPECIFIED. REMOVAL OF RUBBER IS GENERALLY
ACCOMPLISHED BY WATER BLASTING. FEW APPROVED CHEMICAL ARE EFFECTIVE AND
SANDBLASTING IS NOT PERMITTED BY AIR POLLUTION REGULATIONS AT SOME
LOCATIONS. MECHANICAL ABRASION GENERALLY CAUSES DAMAGE TO THE
PAVEMENT.**

**\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\*\***

**A. New Pavement Curing: Allow new pavement surfaces to cure for a
period of not less than 30 days before application of marking
materials.**

**1. Where early painting is required on rigid pavements, a pretreatment
with an aqueous solution containing 3 percent phosphoric acid and 2
percent zinc chloride shall be applied to prepared pavement areas prior
to painting.**

**B. Traffic Controls: \[Section 01500 - Temporary Facilities and
Controls.\] Suitable warning signs shall be placed near the beginning of
the worksite and well ahead of the worksite for alerting approaching
traffic from both directions. Small markers shall be placed along newly
painted lines or freshly placed raised markers to control traffic and
prevent damage to newly painted surfaces or displacement of raised
pavement markers. Painting equipment shall be marked with large warning
signs indicating slow‑moving painting equipment in operation.**

**C. Cleaning: Thoroughly clean surfaces to be marked before application
of pavement marking. Remove dust, dirt, and other granular surface
deposits by sweeping, blowing with compressed air, rinsing with water,
or a combination of these methods as required. Remove \[rubber
deposits,\] \[existing paint or other material markings,\] \[residual
curing compounds,\] and other coatings adhering to the pavement by
waterblasting. Scrub affected areas, where oil or grease is present on
old pavements to be marked, with several applications of trisodium
phosphate solution or other approved detergent or degreaser and rinse
thoroughly after each application. After cleaning oil‑soaked areas, seal
with shellac or primer recommended by the manufacturer to prevent
\"bleeding through.\" Do not commence marking in any area until pavement
surfaces are dry and clean.**

**1. Surfaces shall be recleaned, when work has been stopped due to
rain.**

**2. Cleaning Concrete Curing Compounds: On new portland cement concrete
pavements, cleaning operations shall not begin until a minimum of 30
days after the placement of concrete. All new concrete pavements shall
be cleaned by either sandblasting or water blasting. When water blasting
is performed, thermoplastic and preformed markings shall be applied no
sooner than 24 hours after the blasting has been completed. The extent
of the blasting work shall be to clean and prepare the concrete surface
as follows:**

**a. There is no visible evidence of curing compound on the peaks of the
textured concrete surface.**

**b. There are no heavy puddled deposits of curing compound in the
valleys of the textured concrete surface.**

**c. All remaining curing compound is intact; all loose and flaking
material is removed.**

**d. The peaks of the textured pavement surface are rounded in profile
and free of sharp edges and irregularities.**

**e. The surface to be marked is dry.**

**D. Removal of Existing or Incorrect Markings: **

**1. Identification: When markings must be removed because of conflict
with new markings, obsolescence, or faulty application, these markings
will be identified \[on a drawing\] \[and\] \[or\] \[by the Contracting
Officer\]. New preformed and thermoplastic pavement markings shall not
be applied over existing preformed or thermoplastic markings.**

**2. Removal: The Contractor shall use \[chemical paint remover\]
\[abrasive/air blasting\] \[mechanical abrasives\] or other technique
approved by the Contracting Officer. The technique shall meet OSHA and
local health and safety standards. Whenever grinding, scraping,
sandblasting or other operations are performed the work must be
conducted in such a manner that the finished pavement surface is not
damaged or left in a pattern that is misleading or confusing. When these
operations are completed the pavement surface shall be blown off with
compressed air to remove residue and debris resulting from the cleaning
work.**

**3.2 APPLICATION OF PAINT AND REFLECTIVE SPHERES**

**A. Dimensions of Marking:**

**1. Stripes \[for a solid line\] shall be 4 inches (100 mm) wide
\[and\] \[for a broken line shall be a 10 ft (3 m) strip with a 30 ft (9
m) gap\].**

**2. Symbols shall be of the dimensions as shown on the drawings,
executed with 4‑inch (100 mm) lines.**

necessary to control paint application. Take special precautions in
marking numbers, letters, and symbols. Manually paint numbers, letters,
and symbols. Sharply outline all edges of markings. The maximum drying
time requirements of the paint specifications will be strictly enforced,
to prevent undue softening of bitumen, and pickup, displacement, or
discoloration by tires of traffic. Discontinue painting operations if
there is a deficiency in drying of the markings until cause of the slow
drying is determined and corrected.**

**D. Protection of Markings: The painted area shall be protected from
traffic until the paint is dry.**

**A. Surface Preparation: The surface of the pavement shall be clean,
dry, and free of loose foreign material. The pavement temperature shall
be a minimum of 70 degrees F (21 degrees C).**

**B. Material Preparation: The Raised Pavement Markers (RPM\'s) shall be
warmed prior to setting by heating to a maximum temperature of
120 degrees F ( 49 degrees C)for a maximum of 10 min. The adhesive shall
be maintained at a temperature of 60 to 85 degrees F (15 to 30 degrees
C) before use and during application.**

**C. Mixing Adhesive: The components of the epoxy adhesive shall be
added together and mixed to a smooth uniform blend just prior to use.
Mixed adhesive shall be discarded when polymerization has caused
stiffening and reduction of workability.**

**D. Application of Adhesive: The mixed adhesive shall be applied to the
prepared pavement area to be covered by the RPM and the RPM pressed into
place so as to squeeze out a small bead of adhesive around the entire
periphery of the RPM. The required amount of adhesive per RPM will
normally be in the range of .7 to 1.4 ounces (20 to 40 g).**

**E. Seating RPM\'s: The sequence of operations shall be as rapid as
possible. Adhesive shall be in place and the RPM seated in not more than
30 sec after the removal of the pavement preheat or warm air blast. The
RPM\'s shall not have cooled more than 1 min before seating.**

**F. Bonding: The length of the pavement preheat or warming shall be
adjusted so as to insure bonding of the RPM in not more than 15 min.
Bonding will be considered satisfactory when adhesive develops a minimum
bond strength in tension of not less than 25 lb or a total tension
strength of 800 g/in^2^.**

**G. Alignment: The RPM\'s shall be spaced and aligned as shown on the
drawings or approved by the Contracting Officer. A displacement of not
more than 1/2-inch (12.5 mm) left or right of the established guideline
will be permitted. Improperly placed markers shall be removed and
replaced at no cost to the Government. Pavement markers shall not be
placed over longitudinal or transverse joints in the pavement surface.**

**3.5 APPLICATION OF PREFORMED PLASTIC PAVEMENT MARKING**

**A. Material Application Requirements: The reflective preformed plastic
strip shall be suitable for application on asphaltic or portland cement
concrete pavement. The material shall be applied according to
manufacturer\'s instructions and as called for on the drawings.**

**B. Surface Preparation: The surface of the pavement shall be clean,
dry, and free of loose foreign material. The pavement surface
temperature shall be a minimum of 60 degrees F (15 degrees C) and the
ambient temperature shall be a minimum of 60 degrees F (15 degrees C)
and rising. The preformed markings shall be placed in accordance with
the manufacturer\'s written instructions if they conflict with these
specifications.**

**C. Normal Application: Material shall be cut and laid out prior to
removal of backing. During application only 2 to 3 feet (.6 to .9 m)of
backing shall be removed at one time prior to application of pressure
from a weighted \[steel-drummed\] roller of at least 250 lb (113 Kg).
There shall be no more than 3 splices per 60 yd (55 m) of length.**

**D. Application Over Fresh Asphalt Pavement: When the material is
applied over fresh asphalt pavement, it shall be applied \[immediately\]
\[within \[\_\_\_\_\] min\] after breakdown rolling. The rolling shall
then continue to insure complete inlay of the marking strip and to
obtain the required density of the pavement.**

**E. Standards of Application: The material as applied shall be clean,
free of cracks, and the edges shall be true and straight. Material which
loses adhesion within 6 months of application shall be considered to
have failed and shall be replaced by the Contractor at no additional
cost to the Government.**

**3.6 CLEANUP**

**A. Requirements: Products of the removal shall be cleaned up so as to
leave no visible residues and disposed of off the site so as not to
contribute to air or water pollution in a manner approved by local
authorities.**

**3.7 COORDINATION AND TRAFFIC CONTROL**

**A. Traffic Control at the Work Site: Where pavement marking operations
may interfere or conflict with normal vehicular or pedestrian traffic,
the Contractor shall submit five copies of the traffic control plan to
the Contracting Officer for approval. \[The plan shall be coordinated
with local authorities to take activities and contingencies into
account.\] \[The plan shall meet the requirements of Section 01500 ‑
Temporary Facilities and Controls.**

**3.8 FIELD QUALITY CONTROL**

**A. Markings: Shall present a clean cut, and uniform appearance.
Markings which fail to have a uniform, and satisfactory appearance,
either day or night, will be rejected.**

**B. Tolerances: **

**1. The length of painted segment and gap shall not vary more than
6 inches (150 mm)in a 40 foot (12 m) cycle.**

**2. Painted lines shall be 4 inches (100 mm) wide plus or minus 1/8
inch (3 mm).**

**C. Test Results: Examine material at the job site to determine that it
is the material referenced in the report of test results or certificate
of compliance. A certificate of compliance shall be accompanied by test
results substantiating conformance to the specified requirements.**

**1. Surface Preparations and Application Procedures: Surface
preparations and application procedures will be examined by the
Contracting Officer to determine conformance with the requirements
specified. Approve each separate operation prior to initiation of
subsequent operations.**
