Abstract:
PROBLEM TO BE SOLVED: To provide a method of paving using natural bark facilitating maintenance and control by preventing the bark from scattering and making the surface of a road uneven even at the application of large impact and pressure caused by fast walkers or runners. SOLUTION: To pave the roadbed of a walkway such as a promenade or a running course by laying natural bark, a plurality of net mat layers 5 each formed by filling a bag-shaped net 4 of predetermined sizes with bark are laid along the walkway or running course between a lower bark layer 2 laid directly on the roadbed 1 and an upper bark layer 3 laid on the surface layer of the roadbed, to obtain a layered structure. The bag-shaped net 4 is woven from a flexible rope made of fibers obtained by recycling PET bottles. Preferably, the net consists of a fine upper net and a coarse lower net. COPYRIGHT: (C)2003,JPO
