Manufacturing method of cork chip for road pavement with improved permeability having multi-coating film， cork chip for road pavement manufactured by the same manufacturing method and road pavement method using the same

The present invention is a method for producing and installing an elastic packaging material for replacing a rubber chip using a natural cork chip， by having a structure of a triple coated coating film having respective functions and effects， yellowing of the natural cork chip or It reduces the discoloration phenomenon such as browning， increases the physical properties and adhesion of the cork chip itself， and also ensures the antibacterial properties of the natural cork chip. When used as a road pavement， it has excellent durability such as tensile strength， elongation and hardness， and flat work. This is an easy-to-use road that improves water permeability with a multi-coated film that can be used without deformation for a long period of time by preventing impervious phenomenon due to clogging of surface pores by preventing lifting and bending of packaging materials and providing excellent friction and water permeability. Method for manufacturing cork chips for pavement and cork chips for road pavement manufactured by the method and It provides a road pavement method using the.
