Here is an English technical introduction to thermoplastic road marking requirements:Thermoplastic Road Marking Specifications

1. Material Requirements

• Use hot-melt thermoplastic marking paint compliant with ASTM D713 or EN 1871 standards.
• Glass beads (0.8-1.5mm粒径) with ≥80% retroreflective index must be premixed (18-25% by weight) or surface-applied (200-500g/m²).
• Primer (adhesive agent) should achieve full bonding strength within 2-5 minutes.

2. Surface Preparation

• Clean pavement to SSPC-SP13/NACE No.6 standards (≤0.3% contaminants).
• Apply primer at 0.15-0.25kg/m² when pavement temperature is 10-40°C.

3. Application Parameters
   | Parameter | Specification |
   |————————-|——————————|
   | Melting temperature | 180-220°C (356-428°F) |
   | Line thickness | 1.5-2.0mm (standard) |
   | | 4-6mm (raised profile) |
   | Cooling time | ≤3 minutes (to 50°C) |
   | Application speed | 3-5 km/h (walk-behind units) |
   | Glass bead embedment | 50-60% bead diameter |
4. Performance Standards

• Color: Meet CIE chromaticity diagram requirements
• Skid resistance: ≥45 BPN (pendulum test)
• Wear resistance: ≤80mg loss (CS-17 wheel, 1000 cycles)
• Service life: ≥24 months in heavy traffic (＞20,000 AADT)

5. Tolerances

• Line width: ±5% of design dimension
• Length: ±0.5% of total segment
• Position: ±10mm lateral deviation
• Retroreflectivity: ≥350 mcd/m²/lx (dry), ≥200 mcd/m²/lx (wet)

6. Special Conditions

• Apply anti-slip aggregates (3-5mm粒径) for transverse markings on grades ＞6%
• Use double-layer application for snowy regions (base layer + glass bead layer)
• Maintain 50-70% humidity control during tropical applications

Would you need any specific standards (e.g., MUTCD, ISO 17398) referenced or additional details about particular marking types (arrows, symbols, etc.)?
