beads shall have a minimum of 80% true spheres, minimum refractive index of 1.50.
D. Acceptance.
Acceptance of material shall be based on final inspection per Article DS-23079.03, F and
satisfactory field performance. Pavement markings shall be approved prior to installation on a
project. Approval does not preclude the need for acceptance sampling and testing on a project-
by-project basis.
23079.03 CONSTRUCTION.
A. Contractor Qualifications.
Provide a letter of certification from the preformed thermoplastic pavement marking manufacturer
indicating the Contractor’s qualifications to install their product.
DS-23079, Page 3 of 4
B. Equipment.
All equipment shall be of such design and maintained in such condition as to properly heat, mix,
and apply the material.
C. Surface Preparation.
1. Grooving for pavement markings and legends / symbols and shall be 130 mils -0/+10 mils.
2. The pavement surface on which the thermoplastic material is to be placed shall be clean and
dry. Even if the pavement is visibly dry, subsurface moisture may be present in amounts
sufficient to affect bonding. To test for dryness, a 3 to 6 foot section of tar paper shall be laid
on the pavement and molten thermoplastic applied on top. After 30 seconds, lift the paper
and check for moisture on the bottom of the paper. If the paper is dripping wet, wait until the
pavement has dried before applying the thermoplastic. If the paper shows only a damp spot,
proceed with the thermoplastic application.
3. Pavement surfaces shall be inspected for cleanliness and any dirt, debris, or other
contaminants on the surface to be marked shall be removed.
D. Application.
1. Asphalt.
The material shall be applied as recommended by the manufacturer. The material must be
able to be applied without preheating of the pavement. A primer may be required pursuant to
manufacturers installation requirements.
2. Portland Cement Concrete.
The same application procedure shall be used as described in Article DS-23079.03, D, 1.
However, a primer shall be applied and cured in accordance with the recommendations of the
manufacturer of the thermoplastic material.
3. Glass Beads.
Glass beads shall be applied as recommended by the manufacturers of the thermoplastic
material.
E. General Requirements.
The applied thermoplastic markings will be inspected continually for overall workmanship.
Markings shall have clean cut edges and the color shall be distinctive. The glass beads shall
appear uniform on the entire marking surface.
F. Final Inspection.
1. Provide an acceptable 30 meter geometry retro-reflectometer to use on the project which will
remain the property of the Contractor. In the presence of the Engineer, measure the retro-
reflectivity of selected preformed thermoplastic markings. Take a minimum of five randomly
spaced readings per color line every 1 mile, or per legend or symbol randomly selected per
tenth symbol. Provide the engineer a document indicating results of retro-reflective testing for
the project files. The material, when applied in accordance with manufacturer’s guidelines,
must demonstrate a uniform level of sufficient nighttime retroreflection when tested in
accordance initial minimum retroreflectance values of 300 mcd/sq m/lux for white markings
and 200 mcd/sq m/lux for yellow markings according to ASTM E 1710 (AASHTO T 398). The
minimum retro-reflectivity shall be:
Minimum Coefficient of Retroreflected Luminance (mcd / sq. ft. / ft.-cdl.)
White lines / Symbols / Legends 300
Yellow lines / Symbols / Legends 200
DS-23079, Page 4 of 4
2. If the marking does not meet these initial retro-reflectivity readings, if the marking does not
have the required minimum thickness, or if the marking does not comply with the
specifications for any other reason, the Engineer may require complete removal or correction
at the Contractor’s expense.
23079.04 METHOD OF MEASUREMENT.
Measurement for pavement markings or symbols and legends, satisfactorily placed, will be as follows:
A. Preformed Thermoplastic Pavement Markings.
The number of stations of markings placed will be calculated by the Engineer, using the
beginning and ending points for each type of line placed, based on a single 4 inch width as
outlined in plans. The types are as shown in the plans. The calculations for broken or dotted lines
are adjusted in the table to exclude skips as specified. The calculation for solid lines will be
adjusted to exclude breaks. The quantities for several types of lines will be totaled to a single
quantity of thermoplastic longitudinal 6 inch lines in stations.
B. Preformed Thermoplastic Symbols and Legends.
Each precut symbol or legend is indicated on the plans, and the units will be counted. Each of the
following is a complete unit: each STOP; each SCHOOL legend (one lane or two lane); each RxR
marking for railroad and highway grade crossing; each ONLY; each AHEAD; each freeway,
expressway, and ramp arrow; each straight, curve, or combined arrow; each route shield.
C. Grooves Cut for Pavement Markings or Symbols and Legends.
Per Articles 2527.04, A, 11 and 12 of the Standard Specifications.
23079.05 BASIS OF PAYMENT.
A. Payment for pavement markings or symbols and legends, satisfactorily placed, will be at the
contract unit price as follows:
1. Preformed Thermoplastic Pavement Markings.
For the number of stations of thermoplastic longitudinal lines and transverse markings
placed, the Contractor will be paid the contract price per station.
2. Preformed Thermoplastic Symbols and Legends.
For each unit of precut symbol and legend placed, the Contractor will be paid the contract
price.
3. Grooves Cut for Pavement Markings or Symbols and Legends.
Per Articles 2527.05, A, 11 and 12 of the Standard Specifications.
B. This compensation will be full payment for all work involved in cleaning and preparing the surface
and furnishing, applying, and maintaining the pavement marking, and for furnishing all equipment,
tools, and labor necessary to complete the work. Removal of existing markings is included as a
bid item in the plans and paid for at the contract unit price. The accepted quantity of thermoplastic
pavement marking will be paid for at the contract unit price.
