Understanding International Standards for Thermoplastic Road Marking Paint

When purchasing thermoplastic road marking paint, price and color are only part of the decision.

For highway, municipal and infrastructure projects, buyers also need to determine which technical standard the material should follow.

Three specifications frequently encountered in international road marking projects are:

AASHTO M249 · BS 3262 · JT/T 280

Although all three are related to thermoplastic or road marking materials, they come from different standard systems and are not interchangeable.

Choosing the correct standard depends primarily on the project specification, destination country, tender requirements, road conditions and testing requirements.

What Is AASHTO M249?

AASHTO M249 is an American specification covering white and yellow reflective thermoplastic striping material in solid form.

According to AASHTO, the material is applied to the pavement in a molten state using mechanical equipment, with glass beads applied to the surface. After cooling, it forms an adherent retroreflective stripe designed to maintain its specified color, thickness and width under traffic.

AASHTO M249 focuses on:

• Reflective thermoplastic pavement markings
• White and yellow road marking materials
• Material composition
• Application properties
• Retroreflective marking systems
• Product testing and acceptance
• Packaging and identification

AASHTO M249 is particularly relevant when a tender, consultant or road authority follows U.S.-style highway material specifications.

Typical applications

• Highways
• Expressways
• Main traffic corridors
• Urban arterial roads
• Government infrastructure projects
• Export projects specifically requiring AASHTO specifications

For international buyers, the important point is not simply asking:

“Do you have AASHTO paint?”

Instead, procurement documents should identify the exact AASHTO specification and edition required by the project.

What Is BS 3262?

BS 3262 is a British standard series historically associated with hot-applied thermoplastic road marking materials.

However, buyers should understand an important detail: not every part of BS 3262 has the same current status.

For example, BS 3262-1:1989, covering constituent materials and mixtures, was withdrawn in 2000, while BS 3262-3:1989, covering application of hot-applied thermoplastic materials to road surfaces, is still listed by BSI as current.

Therefore, a tender that simply says:

“BS 3262”

should be checked carefully.

The buyer should confirm:

• Which part of BS 3262 is referenced?
• Which edition is required?
• Is the project using BS 3262 directly or a local specification derived from it?
• What laboratory tests and acceptance criteria are required?

Typical applications

BS-type thermoplastic specifications are commonly encountered in projects influenced by British engineering practice, including some markets in:

• Asia
• Africa
• Middle East
• Commonwealth-related infrastructure systems

The exact requirement always depends on the tender or road authority.

What Is JT/T 280?

JT/T 280-2022 — Road Marking Paint is a current Chinese transportation industry standard.

It applies to the production, inspection and use of road marking paints used for highway traffic markings. The 2022 edition officially replaced JT/T 280-2004.

The standard is administered within China's transportation standardization system and is therefore especially relevant for Chinese highway and road infrastructure projects.

JT/T 280 is relevant to:

• Road marking paint production
• Product inspection
• Highway marking applications
• Material quality control
• Chinese road engineering projects

China also has complementary standards relating to finished road marking performance. For example, GB/T 16311-2024 covers quality requirements and test methods for road traffic markings, while GB 5768.3-2025 covers road traffic markings and took effect on May 1, 2026.

AASHTO M249 vs BS 3262 vs JT/T 280

The following simplified comparison helps international buyers understand their different roles.

The important point is that none of these standards should be selected only because one sounds more international or more demanding.

The project specification should always come first.

How to Choose the Right Standard for Your Project

1. Check the Tender Documents First

For government and infrastructure projects, the tender normally defines the required technical specification.

If the tender says:

AASHTO M249

then the supplier should manufacture and test against the applicable AASHTO requirements.

If it specifies:

BS 3262

the exact part, edition and related project requirements should be confirmed.

For Chinese road projects, the current JT/T 280-2022 should be considered rather than automatically using the older JT/T 280-2004 specification.

2. Consider the Destination Country

Different markets commonly use different specification systems.

For example, a Middle Eastern project may reference AASHTO, British standards or its own national specification.

An African infrastructure tender may combine British-derived specifications with locally defined requirements.

Southeast Asian countries may use national standards while also referencing AASHTO, BS or other international testing methods.

Therefore:

Country ≠ Standard

The actual tender document is always more important than the general market convention.

3. Consider Traffic and Road Conditions

The technical standard is only one part of product selection.

Buyers should also provide the manufacturer with information such as:

Traffic Volume
Heavy trucks and high traffic frequency may require different material properties.

Climate
Hot climates, tropical rainfall, humidity or large temperature variations can influence formulation selection.

Pavement Type
Asphalt and concrete may require different surface preparation and primer systems.

Required Thickness
Different application methods and project specifications require different marking thicknesses.

Reflectivity Requirement
Glass bead type, dosage and application method need to match project requirements.

Customized Thermoplastic Paint for Different Project Specifications

HuaQun's current website lists thermoplastic product categories associated with AASHTO M249, BS 3262 and JT/T 280, and its thermoplastic product listings support customized formulas for different project requirements.

Depending on the project, customization may include:

• Resin system
• Glass bead content
• Color
• Softening characteristics
• Application temperature
• Flow properties
• Packaging
• Private labeling

A representative HuaQun thermoplastic product listing shows an application temperature of 180–220°C, 25 kg packaging and customized white, yellow, blue, red and green options.

For specification-controlled projects, the exact formulation and test report should be confirmed before production.

Which Standard Should You Choose?

A simple purchasing guideline is:

Choose AASHTO M249
when your project or tender specifically follows AASHTO/U.S.-style thermoplastic pavement marking requirements.

Choose BS 3262-related specifications
when the project references British thermoplastic requirements—but confirm the exact BS 3262 part and project specification because the status of individual parts differs.

Choose JT/T 280-2022
when the project follows China's current highway road marking paint specification system.

For projects without a specified standard, the decision should be based on the local road authority requirements, climate, traffic level, pavement conditions and required marking performance.
