歴声質舗装体。Spread bituminous material to form a tack coat layer or prime coat layer on the foundation, and then spread a heated asphalt mixture with a high maximum coarse aggregate ratio and relatively high porosity, such as open-grained asphalt concrete, on top. A heated asphalt mixture layer that has been rolled and pressed is provided, and the upper surface thereof is made of aggregate, filler, and modified asphalt, and the penetration degree of the modified asphalt (conical needle 25°C) is 30 to 100.
A heated modified asphalt mixture that has a softening point of 65 to 120°C and is fluid at high temperatures is spread and rolled to cover the surface of the heated asphalt mixture layer and fill the voids between the aggregates in the upper layer. 1. A textured paving body characterized in that a layer of heat-modified asphalt mixture is provided and integrated.
