Why Do Thermoplastic Road Markings Crack? Causes and Solutions for Vietnam's Tropical Climate
As Vietnam continues to invest in highways, industrial parks, urban roads, and logistics infrastructure, thermoplastic road markings have become one of the most widely used traffic safety solutions.
From Ho Chi Minh City and Hanoi to Da Nang and the Mekong Delta region, thermoplastic road marking paint is preferred for its fast drying time, excellent durability, and high nighttime visibility.
However, many contractors and project owners face the same problem:
Why do thermoplastic road markings crack?
Cracking not only affects appearance but also reduces reflectivity, shortens service life, and increases maintenance costs.
Based on Vietnam's commonly adopted TCVN 8791:2011 standard, this article explains the main causes of thermoplastic marking cracks and how to prevent them.
1. Excessive Temperature Changes
Vietnam's tropical climate creates significant pavement temperature fluctuations.
During dry seasons, asphalt surface temperatures can become extremely high during the day and cool rapidly at night. Continuous expansion and contraction generate stress inside the marking layer.
If the thermoplastic material lacks sufficient flexibility, transverse cracks, edge cracks, and network cracking may occur.
High-quality thermoplastic paint should provide excellent heat resistance, adhesion, and flexibility to withstand Vietnam's environmental conditions.
2. Improper Heating Temperature During Application
Thermoplastic road marking materials are typically applied at temperatures between 180°C and 220°C.
Common construction mistakes include:
Overheating the material
Maintaining high temperatures for excessive periods
Burning or degrading the resin system
These issues reduce the flexibility of the coating and make the markings more susceptible to cracking under heavy traffic.
Using a reliable hydraulic double-cylinder preheater and proper temperature control is essential.
3. Incorrect Marking Thickness
International road marking practices generally recommend a thickness of approximately 2–3 mm for thermoplastic markings.
If the coating is too thick:
Internal stress increases
Cooling becomes uneven
Cracking risk rises
If the coating is too thin:
Wear resistance decreases
Service life becomes shorter
Professional hand-push road marking machines and precision marking shoes help maintain consistent thickness.
4. Poor Surface Preparation
Many industrial and port projects in Vietnam face challenges such as:
Dust contamination
Oil residues
Moist pavement conditions
These factors reduce adhesion between the thermoplastic material and the pavement.
Under continuous heavy vehicle traffic, the markings may crack, debond, or peel off.
Proper cleaning and drying of the pavement before application are critical.
5. Low-Quality Thermoplastic Paint
One of the most common root causes of cracking is poor material quality.
Premium thermoplastic road marking paint typically contains:
Petroleum resin
Titanium dioxide
High-quality fillers
Premixed glass beads
Low-cost materials often reduce resin content or use inferior fillers to cut costs.
Although initial performance may appear acceptable, the markings can crack prematurely under Vietnam's combination of heat, rainfall, humidity, and heavy traffic.
The Importance of Glass Beads
Many buyers consider glass beads only as reflective materials.
In reality, high-quality road marking glass beads contribute to a more uniform marking structure while significantly improving nighttime visibility.
Quality glass beads offer:
High roundness
Excellent transparency
Strong adhesion
Stable refractive index
Combining premix and drop-on glass beads can improve both durability and retroreflectivity.
How to Prevent Thermoplastic Marking Cracks
Professional contractors usually follow these practices:
Use thermoplastic paint compliant with TCVN 8791:2011 and international standards.
Select premium reflective glass beads.
Use professional road marking equipment.
Maintain proper application temperature.
Ensure pavement surfaces are clean and dry.
Control coating thickness consistently.

How Long Do Thermoplastic Road Markings Last in the Philippines? Key Factors Affecting Service Life
As infrastructure development continues across the Philippines, thermoplastic road markings are widely used on highways, municipal roads, airports, industrial parks, and parking facilities.
From Manila and Cebu to Davao and Clark, road authorities and contractors increasingly rely on thermoplastic road marking systems to improve traffic safety, visibility, and long-term maintenance efficiency.
One of the most common questions asked by Philippine contractors and project buyers is:
How long do thermoplastic road markings last?
The answer depends on several factors, including material quality, traffic volume, road conditions, climate, and construction practices.
Philippine Climate and Road Conditions
The Philippines experiences a tropical maritime climate characterized by:
High temperatures
Strong UV exposure
Frequent rainfall
Typhoon seasons
Heavy traffic loads
These environmental conditions can accelerate the deterioration of inferior marking materials.
For this reason, thermoplastic road marking paint has become one of the preferred solutions for Philippine road projects because it offers:
Excellent adhesion
Superior wear resistance
Strong nighttime visibility
Longer service life
Typical Service Life of Thermoplastic Road Markings
Highways
When high-quality materials and proper installation methods are used, thermoplastic road markings on highways typically last around 2–3 years.
Because vehicle movement is relatively consistent, wear tends to be evenly distributed.
Urban Roads
In busy urban environments such as Manila and Cebu, frequent braking, turning, and congestion increase surface wear.
Under normal conditions, thermoplastic markings generally last between 1.5 and 3 years.
Parking Lots and Industrial Areas
Because traffic speeds are lower and vehicle movements are less aggressive, service life can often exceed 3 years.
Why Do Some Road Markings Fail Early?
Many project owners notice that some markings remain highly visible for years, while others begin to deteriorate within months.
The difference is usually caused by four key factors.
1. Thermoplastic Paint Quality
The performance of road markings begins with the formulation.
High-quality thermoplastic paint typically contains:
Petroleum resin
Titanium dioxide
PE wax
Glass beads
Premium mineral fillers
A well-balanced formulation improves adhesion, durability, weather resistance, and reflective performance.
For Philippine road projects, weather resistance is especially important due to high temperatures and humidity.
2. Glass Bead Quality
Glass beads are essential for nighttime visibility.
They directly affect:
Retroreflectivity
Driver recognition distance
Overall marking performance
Proper bead embedment is critical. Industry practice shows that approximately 60% embedment within the coating provides excellent reflective performance.
High-quality glass beads help improve road safety during nighttime driving and heavy rain conditions.
3. Construction Quality
Even premium materials cannot perform well without proper application.
A professional installation process includes:
Surface Preparation
The pavement must be:
Clean
Dry

Are Thermoplastic Road Markings Heat Resistant? Best Road Marking Solutions for Hot Climate Roads in the Philippines
The Philippines has a tropical climate with high temperatures, strong sunlight, high humidity, and frequent rainfall throughout the year. These weather conditions create major challenges for road marking materials, especially in busy cities such as Manila, Cebu, and Davao, where asphalt road surfaces can become extremely hot under direct sunlight.
Because of this, many contractors, importers, and project buyers ask an important question:
Are thermoplastic road markings heat resistant?
The answer is yes — high-quality thermoplastic road marking paint offers excellent heat resistance, but only when the formulation, raw materials, and application process meet professional standards.
What Determines Heat Resistance in Thermoplastic Road Markings?
Thermoplastic road marking paint is mainly composed of:
Synthetic resin
Pigments
Fillers
Glass beads
Functional additives
Among these materials, the resin system and softening point are the most critical factors affecting heat resistance.
Premium thermoplastic paint typically has a softening point of around 90–110°C, allowing it to remain stable even under hot road surface conditions.
Low-quality materials may lead to serious problems such as:
Softening under extreme heat
Tire pick-up
Reduced night visibility
Shorter service life
These problems significantly increase maintenance costs.
Road Marking Requirements in the Philippines
Road construction projects in the Philippines usually require road markings with strong performance in three key areas.
High Reflectivity
Heavy rain and night driving make reflective performance extremely important. Clear road markings help drivers identify lanes quickly and safely.
Wear Resistance
Dense traffic in metropolitan areas creates constant friction, especially from heavy vehicles. Durable markings reduce maintenance frequency.
