A ECO-FRIENDLY PERVIOUS PAVING MATERIAL AND A PERVIOUS PAVING METHOD FOR A COMPLEX, A LANDSCAPE, A PARK, A RIVER, AND A ROAD

摘要

PURPOSE: A nature-friendly water permeable pavement material and a water permeable pavement method are provided to increase intensity, warmness keeping, coldness keeping and sound absorption effects of the pavement layer by an inorganic binder which includes bottom ash and silicate. CONSTITUTION: A nature-friendly water permeable pavement material comprises fine aggregate, bottom ash and an inorganic binder. 85% of the fine aggregate passes through a standard net with a diameter of 5mm. The fine aggregate comprises quartz sand, clam shell powder, granule granite soil, loess, and soil. The bottom ash is heat-treated before being mixed. The inorganic binder comprises 75-85 wt% of silicate, 1-5 wt% of thickening agent, 1-5 wt% of water resistant reinforcing agent, and additive based on 100 wt% of silicate. The additive is one or more selected from a group including a flexibility giving agent, a copper based curing agent, an assistant hardening agent, a wetting agent and an antifoaming agent. A nature-friendly pavement method comprises the following steps: forming a pavement layer by applying the bottom ash and one of coarse aggregate and fine aggregate; and coating the pavement layer with the inorganic binder including silicate.
