Document Type and Number:
Japanese Patent JP6645794
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pavement structure in which a road bed is stacked on a subgrade and further a pavement body is formed on the road bed, the pavement structure preventing a step or a sharp slope from being generated on a road surface at a position at which a structure of the subgrade or a road body under the subgrade changes.SOLUTION: Between a lower layer road bed 5 and an upper layer road bed 7 is provided a settlement suppression layer 6 continuing over both sides of a position at which a structure of a subgrade 4 or a road body under the subgrade changes. The settlement suppression layer 6 includes: granular material including at least any of crushed stone, ballast, and sand; and material having asphalt as its main component. Particles of the granular material are bound by using the material having asphalt as its main component. A net-like body 10 made from steel is embedded in the settlement suppression layer in a direction along a road surface of a pavement body 8, the net-like body dispersing a tensile force and compressive force generated in the settlement suppression layer to gradually cause deformation.SELECTED DRAWING: Figure 2
