の上に透水性舗装材を舗設した舗装構造に関する。[Detailed Description of the Invention] A waterproof adhesive layer is provided on base materials such as roadbeds, subgrades, base layers, surface layers of roads of the present invention, concrete deck slabs and steel deck slabs of bridges, and a water-permeable paving material is applied on top of the waterproof adhesive layer. Concerning paved pavement structures.
従来、道路等の舗装体は不透水性の舗装材を用いたもの
が多かったが、近時、部会の砂漠化を防止し、植物を保
護する等の見地から透水性の舗装材が開発され実用され
るに至っている。In the past, impermeable paving materials were often used for pavements such as roads, but recently, permeable paving materials have been developed to prevent desertification and protect plants. It has come to be put into practical use.
透水性の舗装材を用いると雨水等は舗装体を通り、直接
路床へ浸透し、地中に還元するので自然環境としては好
都合である。Using permeable paving materials allows rainwater to pass through the paving, directly into the roadbed, and return to the ground, which is advantageous for the natural environment.
しかしながら、地中の状態によっては水の影響から路床
、路盤の強度低下をきたし、舗装の破壊をひきおこす。However, depending on the underground conditions, the strength of the subgrade and roadbed may decrease due to the influence of water, leading to destruction of the pavement.
そこで、車道等において路盤、路床の強度維持を図るた
め、舗装構造の中間（路盤、路床の境界）に遮水層（プ
ラスチックフィルム）を設けることなどが提案されてい
る。Therefore, in order to maintain the strength of the roadbed and subgrade on roadways, it has been proposed to provide a water-blocking layer (plastic film) in the middle of the pavement structure (at the boundary between the subgrade and the subgrade).
しかしながら、これはフィルムの継目構造に欠陥を生じ
易（、継目から漏水し、ひいては路床の強度低下へとつ
ながる。However, this tends to cause defects in the joint structure of the film, leading to water leakage from the joints, which in turn leads to a decrease in the strength of the subgrade.
また、通常の車道の舗装体は透水性であることから、路
盤又は基層又は表層の上に透水性舗装材を舗装すること
も提案されている。Moreover, since the pavement of a normal roadway is water permeable, it has also been proposed to pave a water permeable pavement material on the roadbed, base layer, or surface layer.

層等基材との接触面積が少く、通常用いられるアスファ
ルト乳剤系プライマー、プラスチックス系プライマーで
は高温時透水性舗材の流動が発生する。However, since the permeable pavement material is porous, the contact area with the base material such as the lower pavement layer is small, and the commonly used asphalt emulsion primer and plastic primer cause the permeable pavement material to flow at high temperatures.
一方、アスファルト乳剤プライマー、プラスチックス系
プライマー等は低温になると硬質化し、衝撃に弱くなる
と同時に下地になっている下部不透水性舗装層等基材に
亀裂が発生した時にはプライマーも同様に亀裂が入り、
水の浸透のある場合は舗装の破壊につながる。On the other hand, asphalt emulsion primers, plastic primers, etc. harden at low temperatures and become vulnerable to impact.At the same time, if cracks occur in the underlying base material, such as the lower impermeable pavement layer, the primer will also crack. ,
Water infiltration can lead to pavement failure.
