Abstract

The invention discloses a full penetration type bituminous pavement system capable of effectively controlling road rainwater runoff pollution. The problems that an existing full penetration type bituminous pavement has poor system consideration and can only enable water to permeate and be drained after construction, theoretical advantages cannot be exerted, and road greening irrigation and road surface cleaning use plenty of water are solved. The pavement system utilizes a runoff storage module, a runoff utilization module and a water quality monitoring module, which are matched with the fullpenetration type bituminous pavement structure, to solve the problem of local absorption of pavement rainwater runoff during rainfall on the premise of ensuring that the road traffic function is not affected. At the same time, the real-time monitoring of a regular index of reclaimed runoff water quality is achieved, the system operation and a maintenance scheme are easy to adjust flexibly, water quality of sprinkling irrigation and road cleaning is further ensured, pollution of road rainwater runoff is alleviated, and water use problems of urban road greenbelt irrigation and road cleaning areeffectively solved.

Description

technical field [0001] The invention belongs to the technical field of municipal engineering, and specifically relates to a system that integrates the penetration, collection, purification, storage, reuse and water quality monitoring of rainwater runoff on the road surface, can alleviate the pollution of rainwater runoff on the road surface, and can effectively solve the problem of urban road green space irrigation and road surface drainage. A fully permeable asphalt pavement system that can effectively control rainwater runoff pollution on the pavement for cleaning water problems. Background technique [0002] Traditional impermeable urban roads are the main component of urban water catchment, and also the main place where road runoff and its pollutants are produced. Pollutants such as particulate matter, nutrient salts, heavy metals, and polycyclic aromatic hydrocarbons accumulate on the road surface on sunny days. When it rains, these pollutants dissolve in the rainwater ...
