Thermoplastic road markings are a critical component of safe, durable, and compliant road infrastructure in the Philippines. For contractors, engineers, and DPWH stakeholders, understanding the technical specifications, application methods, and lifespan of thermoplastic road marking Philippines is essential. Rua Seguridad Corporation brings you this complete technical guide, aligned with DPWH 2024-2025 standards, to serve as your flagship reference.
1. Types of Thermoplastic Road Markings
Thermoplastic road markings can be applied using three primary methods:
- Screed Method
- Ideal for high-volume traffic areas and highways.
- Provides thick, uniform markings.
- Requires specialized screed machines for precise application.
- Ideal for high-volume traffic areas and highways.
- Extrusion Method
- Material is extruded directly onto the road surface.
- Allows consistent thickness and excellent adhesion.
- Commonly used for center lines and lane markings.
- Material is extruded directly onto the road surface.
- Spray Method
- Best suited for retroreflective applications.
- Faster application for long stretches of road.
- Often combined with glass beads to improve night visibility.
- Best suited for retroreflective applications.

2. Binder Composition
The quality and performance of thermoplastic road markings depend on the binder composition. Typical components include:
- Synthetic resins: Ensure flexibility and adhesion to asphalt or concrete.
- Plasticizers: Improve workability at high temperatures.
- Pigments: Provide visibility and durability under Philippine UV exposure.
- Glass beads: Embedded for retroreflectivity, enhancing night-time visibility.
Rua Seguridad Corporation’s thermoplastic formulations are optimized for tropical conditions, ensuring excellent durability and performance across the Philippines.
3. Recommended Thickness & Application Temperatures
Proper application is crucial for compliance and longevity. DPWH standards (2024-2025) recommend:
| Marking Type | Recommended Thickness | Application Temperature |
| Screed / Extrusion | 1.5 – 3.0 mm | 180–200°C |
| Spray | 0.8 – 1.2 mm | 180–200°C |
Applying thermoplastic within these parameters ensures adhesion, durability, and compliance with DPWH specifications.
4. DPWH Standard Specifications
Compliance with DPWH specifications is mandatory for all public roads in the Philippines. Key standards include:
- Glass bead content: 15–25% by weight for standard lane markings.
- Retroreflectivity: Minimum 250 mcd/m²/lux for high-visibility areas.
- Color specifications: White and yellow conforming to DPWH traffic guidelines.
- Binder quality: Must meet DPWH 2024-2025 technical specifications for road marking longevity.

5. Typical Lifespan in Philippine Climate
The lifespan of thermoplastic road markings in the Philippines depends on traffic volume, climate, and application quality:
- Urban roads: 2–3 years
- Highways / Expressways: 3–5 years
- Heavy rainfall or coastal areas: May require more frequent maintenance
Regular inspection and maintenance, combined with quality thermoplastic products, extend service life and enhance road safety.
Thermoplastic road markings are vital for safe, durable, and compliant road infrastructure in the Philippines. By understanding types, binder composition, thickness, DPWH standards, and typical lifespan, contractors and engineers can deliver long-lasting, high-quality markings that withstand local climate conditions.
Rua Seguridad Corporation offers a complete range of thermoplastic products, primers, and glass beads, ensuring compliance, performance, and durability for every project.
