Description
Technical Field
The invention relates to the technical field of pavement structures, in particular to a fiber implanted permeable pavement structure.
Background
With the development of times, the performance limitation of the traditional impermeable road surface is more and more obvious. The traditional urban road is paved by multipurpose asphalt mixture or cement concrete, has no water permeability, realizes water drainage by the transverse slope of a road arch, and has the possibility of causing water accumulation on the road surface when the water drainage is too large or the road is blocked in rainy seasons. The waterproof road surface can not timely discharge accumulated water in the use range, so that normal running of vehicles is hindered, and road performance is seriously affected. For example, the asphalt pavement can generate aggregate segregation and asphalt stripping phenomena under the action of water for a long time, further causing pavement diseases such as pits and grooves of the asphalt pavement, and affecting the service life of the pavement after a long time; if the accumulated water of the base layer under the panel can not be drained in time, the mud pumping phenomenon is easy to generate, and the service performance of the pavement is seriously influenced. In addition, the compatibility between the impervious pavement and the environment is poor, the hardened pavement changes the ground evaporation circulation system, is an important reason for causing urban waterlogging and heat island effect, and is not beneficial to the construction of ecological cities, so that the hardened pavement does not accord with the modern green road construction concept and the environment protection concept.
Aiming at the defects of the traditional impermeable road surface, the design concept of the permeable road surface is developed at the same time. The water permeability road surface is the novel road surface design that rainwater permeates the structural layer through the road surface in a large number, gets into marginal drainage facility through the lateral flow and reaches the drainage effect. At present, permeable asphalt, permeable concrete and other permeable materials are mostly used for the design of permeable pavements to achieve the effects of seeper permeation and drainage, but the permeable pavements are high in cost and not suitable for large-scale popularization.
