A VOLCANO-PEBBLE PAVEMENT COMPOSITE AND A PERMEABLE STRUCTURE USING THE SAME

摘要

PURPOSE: A volcano-pebble pavement composite and a water permeable structure using the same are provided to improve water-permeability of volcano-pebbles and to prevent heat island. CONSTITUTION: A volcano-pebble pavement composite comprises 65-90 weight% of volcanic rock aggregate and 10-35 weight% of urethane-based environmentally-friendly binder. The urethane-based environmentally-friendly binder improves the rigidity of the volcanic rock aggregate.
