Urban areas are facing increasing challenges related to stormwater management, flooding, and urban heat island effects. Permeable pavements are widely recognized as a key component of Low Impact Development (LID) and sponge city strategies, but most applications rely on cement-based pervious concrete or porous asphalt.

Resin-bound systems, such as PurePave, are emerging as innovative alternatives with distinctive features:

✅ Superior mechanical performance (Flexural strength >6 MPa, Compressive strength ~39 MPa) ✅ Freeze-thaw resilience (no mass loss and no strength loss) ✅ Ultra-high infiltration capacity (up to 38,000 L/m²/hr) ✅ Decorative and long-lasting aesthetics

Discussion points:

Can resin-bound permeable pavements, like PurePave, outperform traditional permeable pavement systems in durability, lifecycle cost, and sustainability. What opportunities or challenges exist for their adoption in sponge cities and climate-resilient urban design?

I’d love to hear your research insights, case studies, or expert opinions on:

• Field performance in various climates
• Barriers to large-scale implementation
• Environmental benefits and regulatory perspectives

If you’ve studied, tested, or implemented similar systems, or have thoughts on PurePave’s potential, please share your experience!
