Key Differences
- Particle Size:
- BS6088B has a smaller particle size range (90–850 µm) compared to BS6088A (600–1400 µm), making it better suited for drop-on applications where uniformity and adhesion are critical.
- AASHTO Type II beads have smaller particles (300–600 µm), making them ideal for low-traffic and temporary markings.
- Retroreflectivity:
- BS6088B and EN1423 offer higher retroreflective performance compared to AASHTO Type II, making them suitable for critical applications such as highways and airports.
- Durability:
- BS6088B and EN1423 beads have excellent durability, while AASHTO Type II beads are less durable and suitable for low-traffic areas.
- Standards Compliance:
- BS6088B complies with British Standards, while EN1423 is aligned with European Standards, and AASHTO beads meet American standards. Selection depends on regional requirements.
- Cost Efficiency:
- BS6088B offers a balance of cost and performance, making it a versatile choice for most applications. AASHTO Type II beads are more economical but less reflective and durable.
Conclusion
- BS6088B Glass Beads are ideal for a wide range of applications due to their excellent retroreflectivity, durability, and compliance with international standards. They are particularly well-suited for urban roads, highways, and airports.
- For projects requiring larger bead sizes or enhanced wet condition performance, BS6088A or EN1423 may be a better choice.
- AASHTO Type II Glass Beads are a cost-effective option for low-traffic or short-term applications.
This table provides a clear comparison to help you choose the most suitable product for your specific road marking needs.
