Permeable Pavement Permeable Functional Urban Road Design Calculations And Applied Research

Heavy use of impermeable pavement in urban surface caused a series of environmentalproblems such as lack of sea water, groundwater, heat island effect etc. Along with the rapiddevelopment of urbanization, urban construction urgently needs a kind of benefit in theprocess of improving urban ecological environment of road pavement structure, road researchand use of the permeable pavement arises at the historic moment. In this paper the permeablemechanism of permeable pavement and its percolation, runoff mechanism analysis andresearch. In Qingdao area rainfall characteristics analysis and calculation of the same flowlaw of permeability coefficient under the condition of different return period; Summarizes thecurrent test method for determination of permeability coefficient at home and abroad, putsforward the indoor steps and the method for determination of the coefficient of permeabilityof the permeable pavement structure, and application of the method to determine the Qingdaoarea is a typical three kinds of permeable pavement permeability coefficient; By Qingdaoregional permeable pavement research puts forward a universal problem in use process, andputs forward the solution.
