Storage-infilltation type permeable pavement for roadways and heavy traffic roads

Overview

This permeable asphalt pavement for roadways can draw rainwater underground in the same way as natural ground. While permeable pavement technology that has been used to date on sidewalks and in parking lots has been harnessed, improvements in terms of durability and aggregate scattering resistance have been made to expand this product’s applicability to heavy traffic roads.

Features

  1. Compatibility with roadways: Widely applicable from light traffic roads to heavy traffic roads.
  2. Environmental conservation: Contributes to the conservation of the water cycle and is also effective for reducing road traffic noise.
  3. Safety and comfort: Inhibits rainwater splashing and hydroplaning.
  4. Resource conservation: Pavement materials can potentially be made from industrial by-products.

Uses

  • Permeable pavement on roadways
