When purchasing thermoplastic road marking paint, buyers often ask whether products manufactured according to China’s JT/T 280 standard can meet AASHTO M249 requirements.
Both standards are related to road marking materials, but they are not identical. They use different classifications, test methods and acceptance requirements. Therefore, a product that complies with one standard should not automatically be described as complying with the other.
For tenders and government road projects, the buyer should provide the complete standard number, edition and required test items before the manufacturer confirms the formulation.
What Is AASHTO M249?
AASHTO M249 is an American material specification for white and yellow reflective thermoplastic pavement marking material supplied in solid form.
It is commonly referenced in road marking tenders and highway projects that follow American specifications.
The standard covers important material properties related to thermoplastic pavement markings, which may include:
Material composition
Colour
Heating and application performance
Softening behaviour
Flow characteristics
Glass bead content
Water absorption
Impact resistance
Durability-related properties
The exact requirements depend on the edition specified in the tender.
Some older project documents may refer to AASHTO M249-98, while current documents may use a later edition. Buyers should not assume that different editions contain exactly the same requirements.
What Is JT/T 280?
JT/T 280 is a Chinese transportation industry standard for road marking coatings.
The current edition, JT/T 280-2022, covers several types of road marking materials rather than only one thermoplastic product.
Depending on the product category, the standard contains requirements for:
Appearance and colour
Density
Drying performance
Softening point
Compression resistance
Wear resistance
Alkali resistance
Water resistance
Heating stability
Coating performance
Glass bead content
Other physical and application properties
JT/T 280 is widely used for Chinese highway, municipal road, national road and provincial road projects.
Older tenders may still refer to JT/T 280-2004, so the manufacturer must confirm whether the buyer requires the 2004 or 2022 edition.
Are AASHTO M249 and JT/T 280 Equivalent?
No. AASHTO M249 and JT/T 280 should not be treated as completely equivalent standards.
They have a similar purpose because both can be used to evaluate thermoplastic road marking materials. However, they differ in several areas:
1. Standard System
AASHTO M249 belongs to the American highway material specification system.
JT/T 280 belongs to China’s transportation industry standard system.
2. Product Scope
AASHTO M249 focuses on white and yellow reflective thermoplastic striping material supplied in solid form.
JT/T 280 covers a broader range of road marking coatings and classifies products according to their material type and performance.
3. Test Methods
The two standards may use different specimen preparation methods, testing conditions, equipment and calculation methods.
Even when two test items have similar names, their procedures and acceptance limits may not be the same.
4. Technical Requirements
Requirements for resin, pigments, fillers, glass beads and other components may differ between the two standards.
A formulation designed for JT/T 280 should therefore be reviewed and, when necessary, adjusted before being offered for an AASHTO M249 project.
5. Tender Acceptance
The final acceptance standard is determined by the tender document, project specification and designated testing laboratory.
A general factory test report cannot replace the specific documents required by the project.
Can a Chinese Manufacturer Produce AASHTO M249 Thermoplastic Paint?
Yes. A Chinese road marking material manufacturer can develop and produce thermoplastic paint according to AASHTO M249 requirements.
However, the buyer should first provide:
Complete standard number
Required edition or publication year
Product colour
Project location
Climate conditions
Pavement type
Application thickness
Required glass bead content
Laboratory test requirements
Packaging requirements
Estimated order quantity
The manufacturer can then review the specification, adjust the formulation and arrange relevant testing.
Compliance should be confirmed by test results based on the specified edition rather than by comparing only the product name.
Which Standard Applies to Road Marking Glass Beads?
The paint standard and glass bead standard should be confirmed separately.
For projects using the AASHTO system, road marking glass beads are commonly specified according to AASHTO M247.
For projects using Chinese standards, road marking glass beads are commonly specified according to GB/T 24722.
A tender may also specify other glass bead standards, particle-size distributions, refractive indices or surface treatments.
The buyer should provide the complete glass bead standard instead of writing only “AASHTO glass beads.”
Why Are Glass Bead Requirements Important?
Glass beads provide nighttime retroreflection by returning vehicle headlight illumination toward the driver.
Thermoplastic road marking systems may use:
Premixed Glass Beads
Premixed beads are incorporated into the thermoplastic material during production.
As the marking surface gradually wears, newly exposed beads help maintain nighttime visibility.
Drop-On Glass Beads
Drop-on beads are applied to the molten thermoplastic surface immediately after the marking is installed.
Their performance depends on:
Particle-size distribution
Refractive index
Roundness
Surface coating
Application rate
Bead embedment
Paint temperature during application
The thermoplastic paint and glass beads should be evaluated as one complete road marking system.
What Information Should Be Checked in a Tender?
Before quoting for a road marking tender, the supplier and buyer should check the following details.
Standard Edition
Confirm whether the tender requires an older edition or the latest edition.
For example, AASHTO M249-98 is not the same edition as later versions of AASHTO M249.
Paint Colour
Confirm whether the project requires white, yellow or another colour.
Colour coordinates and luminance requirements may be included separately in the tender.
Glass Bead Standard
Check whether the project requires AASHTO M247, GB/T 24722, EN 1423 or another standard.
Premixed Bead Content
Confirm whether the thermoplastic paint must contain premixed glass beads and the required percentage.
Drop-On Bead Application
Confirm the required bead type and application rate for the completed marking.
Application Thickness
The required marking thickness affects material consumption, construction performance and final cost.
Climate and Pavement
High-temperature, tropical, humid or cold environments may require different formulations.
The supplier should also know whether the material will be applied to asphalt, concrete or an existing marking.
Required Documents
Confirm whether the buyer requires:
Technical data sheet
Safety data sheet
Certificate of analysis
Factory test report
Third-party test report
Certificate of origin
Product samples
Packaging photographs
How Should Buyers Compare Quotations?
Buyers should not compare thermoplastic paint quotations only by price per tonne.
A proper comparison should include:
Applicable standard
Standard edition
Material composition
Premixed glass bead percentage
Colour performance
Recommended thickness
Theoretical consumption
Packaging weight
Required primer
Drop-on bead dosage
Testing and documentation
Expected application conditions
A lower price may represent a different formulation, lower glass bead content or different performance level.
All suppliers should therefore quote according to the same technical specification.

Frequently Asked Questions
Is JT/T 280 the Chinese equivalent of AASHTO M249?
They have similar applications, but they are not directly equivalent. Their scopes, classifications, test methods and technical requirements differ.
Can JT/T 280 thermoplastic paint be used for an AASHTO project?
The formulation must first be checked against the required edition of AASHTO M249. Additional formulation adjustment and testing may be necessary.
Does AASHTO M249 also cover glass beads?
The thermoplastic material specification may contain requirements related to the reflective material, but pavement marking glass beads are normally specified separately under AASHTO M247.
Which Chinese standard covers road marking glass beads?
GB/T 24722 is commonly used for road marking glass beads in China.
Can the manufacturer issue an AASHTO M249 certificate directly?
The manufacturer can provide internal quality documents and available test reports. If the tender requires independent certification, testing must be completed by an accepted third-party laboratory according to the specified edition.
What should I send before requesting a quotation?
Please send the complete tender document, standard edition, colour, quantity, packaging, glass bead requirements, destination port and required certificates.
Conclusion
AASHTO M249 and JT/T 280 are both important road marking material standards, but they cannot be considered interchangeable.
For tender projects, buyers should provide the exact standard, edition and individual test requirements. The manufacturer can then select or customize the formulation and arrange the required quality verification.
