FREE-GRADIENT PORTAL SIDE DITCH FOR PRECAST CONCRETE STREET GUTTER HAVING APRON PAVED WITH ASPHALT
PROBLEM TO BE SOLVED: To form an asphalt pavement bicycle travel lane by eliminating a change of a 6% apron slope and a 2% roadway section cross gradient in a free-gradient portal side ditch having a top surface formed as an L-shaped street gutter.SOLUTION: The vicinity of a gutter bottom employs a drop cover with a curb, which serves as a top surface pavement stop. An asphalt top surface pavement with a 2% gradient is applied to a surface including an apron surface. A side strip suitable for bicycle travel is provided.SELECTED DRAWING: Figure 1
【課題】 上面がＬ形街渠の自由勾配門形側溝において６％エプロン傾斜と２％車道部横断勾配の変化を無くし、アスファルト舗装自転車走行帯を形成する。【解決手段】 渠底近くが上面舗装止めとなる縁石付落し蓋を用い、エプロン面も含めて２％勾配のアスファルト上面舗装とし、自転車走行に適した路側帯を設ける。【選択図】図１
