Paving method using stone powder for water permeable cement concrete road

摘要

PURPOSE: A permeable cement concrete road pavement method using powered limestone is provided to prevent powered limestone from sticking or lowering on strength cause by shortage of moisture, to promote convenience on construction by simplify a process and to be used for manufacturing permeable blocks. CONSTITUTION: The permeable cement concrete road pavement method using powered limestone comprises the steps of: putting water to powered limestone according to moisture content and keeping for 2 hours or more; mixing cement with the water-absorbed or saturated powered limestone; paving a powered limestone permeable cement concrete layer on the paved and hardened subsidiary base layer or macadamized base layer; paving a surface layer on the upper part of the powered limestone permeable cement concrete layer; after hardening the powered permeable cement concrete layer or the surface layer with a roller, then covering with vinyl and curing fabric and curing the surface.
