1.2. Material under this contract may include, but is not limited to Bulk Thermoplastic, Preformed Thermoplastic (pre-heat) Type IV, Preformed Thermoplastic (no pre-heat) Type IV, Preformed Thermoplastic (linear) pre-heat, Preformed Thermoplastic (linear) no pre-heat, accessories, and primers/sealers.

2. Introduction and Background

2.1. The supplied materials and accessories will be used by Department crews statewide for the maintenance and installation of pavement markings. The majority of those markings will be transverse. Transverse markings are those normally placed across and/or in traffic lanes, such as crosswalk lines, stop lines, turn arrow symbols and word legends.

3. General Requirements

3.1. The preformed marking materials and accessories are a pavement marking system in which symbols and legends are supplied in their final form and applied by means of adhesive or heat fusion. The hot-melt thermoplastic and preformed marking materials, hereafter referred to as pavement markings, are to be fully compatible to the applicable requirements of the Manual of Uniform Traffic Control Devices (MUTCD) Part 3. MARKINGS and any other related Federal Highway Administration (FHWA) documents.

3.2. The pavement markings shall conform to applicable requirements of the American Association of State Highway and Transportation Officials (AASHTO), Standard Specifications for Transportation Materials. The exceptions to the AASHTO specification relate to those relevant differences that the pavement markings need to achieve its preformed state and its application and performance characteristics herein described and required.

3.3. The pavement marking material specified in this contract shall be referred to as the “Arizona Maintenance Standard” (AZ Maint. Std.) formulations. The requirements for this material differ from that specified in the Department’s “Standard Specifications for Road and Bridge Construction” — “Section 704 Thermoplastic Pavement Markings” and “Section 705 Preformed Pavement Marking.” The formulation differences herein specified are intended to allow the Department the ability to better assess cost and performance to help ensure resources are being properly allocated.

3.4. The pavement marking material supplied shall be fully compatible and suitable to be placed on newly laid asphaltic pavement surfaces, micro-sealed surfaces, chip-sealed surfaces, Portland cement concrete surfaces and surfaces that have been previously striped with paint, thermoplastic or epoxy pavement marking materials. The Contractor shall give detailed recommendations and/or site visit(s) on how the material is to be applied on each surface so the Department can achieve its maximum durability and performance. A surface application guide matrix should be included in the user’s manual and in the training session furnished as a part of this contract.

3.5. The pavement marking material supplied and the use instructions and training provided by the contractor shall account for all of the applicable federal (Environmental Protection Agency, FHWA, OSHA, etc.), state and local regulations governing its shipment, handling, use, clean-up and disposal.

3.6. The pavement marking material supplied shall not contain mercury, lead, hexavalent chromium, toluene, chlorinated solvents, hydrolysable chlorine derivatives, ethylene-based glycol ethers and their acetates, nor any carcinogen, as defined in 29 CFR 1910 \ 1200of OSHA Standards.

3.7. The pavement markings shall be suitable for applications on all types of pavement surfaces. Upon application (including cooling) the material shall be immediately ready for traffic. Additionally, after being applied (including thermally molded and fused) to the pavement surface the material shall maintain all of its performance characteristics, making it a useful and durable pavement marking symbol, legend, line (e.g. shape, color, skid resistance, retroreflective appearance) or adhesive (hold the marker or channelizer down on the pavement to its intended alignment).

3.8. Besides being fully compatible with all pavement surfaces, the pavement markings shall also be suitable as a re-stripe material. The material shall also have a resealing characteristic that allows it to fuse to previously applied hydrocarbon or alkyd thermoplastics.

3.9. After proper application and sufficient drying time, the markings produced utilizing the thermoplastic products supplied shall show no appreciable deformation or discoloration under local traffic conditions with road surface temperatures ranging from -10 degrees to +200 degrees Fahrenheit (F).

3.10. The pavement markings shall be specifically formulated to withstand all of Arizona's roadway environments while maintaining its needed shape, color, skid resistance, presences and retroreflective appearance. The retroreflective appearance requirement does not apply to adhesive pads. The materials shall, as a minimum, come with a one-year storage warranty and a one-year field performance and durability warranty. This requirement assumes that the pavement markings are properly installed and the underlying pavement stays in-place and does not fail. It is anticipated that the material will last longer.

3.11. The installation requirements shall be straightforward and simple. The pavement markings shall be designed to be installed on clean dry pavement, with a one or two person crew, with little if any special equipment (e.g. propane-fueled heat torch), and minimal or no surface preparation.

4.2. Bulk Hot-Melt Thermoplastic

4.2.1. The thermoplastic material shall be white, yellow or black colored alkyd binder formulation, which is compatible for the gravity feed contact extrusion equipment, and application methods used by the Department’s maintenance crews.

4.2.2. The bulk thermoplastic material supplied through this contract will be used to maintain mostly crosswalk, stop bar, legend and symbol pavement markings. Once melted, the material will be applied to new and old asphaltic concrete (AC) pavement, portland cement concrete (PCC) pavement and existing pavement markings, of either thermoplastic, paint or epoxy.

4.2.3. The bulk thermoplastic shall be capable of performing as specified herein when subjected to high traffic volumes and severe wear conditions such as repeated shear action from crossover or encroachment on edge and channelization lines, starting, stopping, and turning movements.

4.2.4. The bulk hot-melt thermoplastic pavement marking material shall consist of a 100% solid mixture of heat stable resins, white, yellow or black pigment, inter-mixed glass beads, filler, and other materials in granular or block from specifically compounded for reflectorized (white and yellow only) pavement markings to be applied to the pavement in a molten state via a hand cart extrusion method. The drop-on glass beads, which are purchased by the Department from another source, will be dropped on to the surface of the white and yellow molten material immediately after it has been extruded on to the pavement surface.

4.2.5. The flow characteristics of the molten thermoplastic shall be such that complete and even coverage of the surface being striped can be achieved through the extrusion dies used by the Department.

4.2.6. The characteristics of the liquefied material shall be such that complete and even coverage of specified width and thickness as a line, legend or symbol is provided by the required application method and rate. Upon cooling to normal pavement temperature, this material shall produce an adherent reflectorized (white and yellow only) pavement marking capable of resisting deformation and wear in the roadway.

4.2.7. The white colored alkyd hot-melt thermoplastic formulation will be used for symbols, legends and transverse lines, including stop bars (or lines) and crosswalks where vehicles typically stop, wait, accelerate and turn. Therefore, the thermoplastic material used to make these pavement markings will be subjected to constant wheel loading and vehicle drippings (oils, fuel, antifreeze, hydraulic fluid, etc.). Combining these factors with Arizona hot desert climate presents an extremely harsh environment for pavement markings. The thermoplastic formulation supplied shall be configured to account for these factors so the markings, if properly applied at thicknesses from 90 to 125 mils, have the ability to have durable and proper function for at least 1 year or longer on any roadway or pavement surface. All thermoplastic shall be warranted to perform as such if they are properly applied by the Department in the field.

4.2.8. The white and yellow bulk hot-melt thermoplastic material will also be used for reflectorized lane, edge, storage, cross hatch and gore line applications. The yellow will be used for school crosswalks and channelization lines.

4.2.9. The black hot-melt thermoplastic material may be used by the Department to enhance contrast of either white or yellow pavement markings.

4.2.10. Physical Characteristics of the Composition

4.2.10.1. The pavement marking material shall not exude fumes which are toxic, injurious or require specialized breathing apparatus when heated to the temperature range specified by the manufacturer for application. The material shall remain stable when held for four hours at this temperature, or when subjected to four reheating’s, not exceeding a total of four hours, after cooling to ambient temperature. The temperature viscosity characteristics of the plastic material shall remain constant throughout the reheating’s and shall show like characteristics from batch to batch. There shall be no obvious change in color of the thermoplastic material as a result of reheating, and the color of the material shall not vary from batch to batch.

4.2.10.2. After being heated to application temperature and then cooled the material shall meet the following color requirements: When tested, according to ASTM D6628. The pigments shall be selected and blended to provide a white or yellow marking film which conforms to standard highway colors throughout the expected life of the film.

4.2.10.2.1. The minimum skid resistance, when tested according to ASTM E 303 "Standard Test Method for Measuring Surface Frictional Properties Using the British Pendulum Tester" shall be at least 45.

4.2.10.2.2. Provided the bulk hot-melt thermoplastic material is properly applied by the Department with a single drop glass bead rate of ten pounds per 100 square feet of AASHTO M247 Type I glass beads for short line pavement markings, and double drop glass bead rate of six pounds per 100 square feet per drop of FP-96 Type III glass beads and AASHTO M247 Type I for long line pavement markings. Thermoplastic materials supplied for long line pavement markings shall have the following minimum retroreflection intensity values (retroreflectance in millicandelas) as measured by the Department in accordance with ASTM E-1710 using an LTL-X Delta Retrometer or similar device, within 30 days of application, but no sooner than three days after application to the roadway surface, unless loose beads are hand swept from test location.

4.2.10.2.6. For transverse lines two measurements are to be taken per lane (one wheel path and center of the lane) for which the line crosses (up to a maximum of 20 measurements);

4.2.10.2.7. For Long line pavement markings (continuous longitudinal lines), the testing will be performed every 0.2 mile, with four readings (averaged) taken at each location. The four readings shall be taken randomly within a 10 foot section. A minimum of 20 readings shall be taken per line. The spacing of these measurements is to be roughly at the start, midpoint and end point for the line being measured. The minimum distance between any one measurement should be three feet.

4.2.10.2.8. For Long line pavement markings (skip or 12 inches white turn lanes) lines a total of four readings per lane line are to be taken with a minimum number of ten lane lines to be sampled. The spacing of the lines to be sampled should be at the start, midpoint and end point in the area to be measured.

The minimum distance between the two measurements should be two feet.
