Asphalt pavement, asphalt pavement road surface structure and method of forming asphalt pavement

摘要

PROBLEM TO BE SOLVED: To provide an asphalt pavement body and an asphalt pavement road surface structure which can suppress scattering of particulates packed in a gap of a porous layer; and a method for forming the asphalt pavement body.SOLUTION: An asphalt pavement body 12 comprises a porous layer 14 using an asphalt mixture as a base, a group of particulates which is packed in a gap of the porous layer 14 so as to form micropores 17, a group of grains which is packed closer to the side of a surface layer 15 than the group of particulates in the gap of the porous layer 14 so as to form pores 18, a hydrophobic resin 23 which bonds grains 22 constituting the group of grains with each other in the surface layer 15 of the porous layer 14, and a surface active agent 25 which attaches to the inside walls of the pores 18 and which forms a hydrophilic film in the surface layer 15.SELECTED DRAWING: Figure 2
