ROAD SURFACE CONSTRUCTION METHOD FOR ROAD FOR WORK IN FOREST

摘要

PURPOSE:To prevent collapse of a road for a work, built on the slope of a forest on a mountain, owing to rainwater by a method wherein used tires are arranged on the whole surface of the width of the road surface of the road for a work built on the slope of a forest on a mountain. CONSTITUTION:Used tires T are juxtaposed on the whole surface of the width of a road surface R or at intervals of a given distance in the longitudinal direction of the road surface R. Further, covering earth A is applied on the surfaces of the used tires T. Further, in a case of the road surface R being a steep slope, the used tires T are intercoupled by means of a wire and laid in a multilayer. The whole of the road surface R is unfiformly reinforced by the used tires T juxterposed with each other. Rainwater is dammed at the outside of the used tires T. Simultaneously, rainwater is drained through earth with which the inner circular hole 1 of the used tire T or a gap 2 between the used tire are filled. Since an amount of water flowing from the road surface R directly to a road shoulder S is reduced, a face B of a slope is prevented from collapse.
