Hydraulic and Environmental Performance of Porous Pavement in Cold Climates

低影响开发(LID)技术是一种相对较新的雨水管理策略，旨在减少或消除对传统雨水基础设施的需求。一个受欢迎的盖子是透水性路面，因为它可以在现场处理雨水的水量和水质。透水性路面是一种透水性较高的路面，可以收集、储存和处理雨水径流。该系统允许雨水从地面流向下部结构(从地面铺装层底部到路基顶部的区域，包括垫层、蓄水层和土工布)。如果没有防渗层，水最终会到达排水沟，或者被允许进一步渗透到周围的土壤中，以补充地下水。雨水暂时储存在可渗透材料的子结构中

Low Impact Development (LID) technology is a relatively new stormwater management strategy developed to reduce or eliminate the need for traditional stormwater infrastructure. One popular LID is porous pavement because it can treat stormwater both in terms of water quantity and quality on site. Porous pavement is a pavement with a high permeability and thus, can collect, store and treat stormwater runoff. The system allows stormwater to flow from the surface to a sub-structure (the region spanning from the bottom of surface pavement layer to the top of the subgrade and includes the bedding layer and reservoir course and a geotextile). The water finally reaches a subdrain or is allowed to further infiltrate into the surrounding soil to recharge groundwater if there is no impervious liner. Stormwater is temporarily stored in sub-structure of the permeable
