Problems solved by technology

[0003] In view of the problems existing in traditional concrete pavement, many research institutes at home and abroad are currently researching permeable concrete. However, there are still two common problems in functional permeable concrete: (1) Permeable concrete has insufficient strength or poor water permeability; (2) The surface of the concrete is airtight, and it is easy to form a "heat island phenomenon"

Abstract

The invention belongs to the technical field of highway construction, and particularly relates to a permeable pavement material and a preparation method and an application method thereof. The permeable pavement material provided by the invention comprises the following components in parts by weight: 4-5 parts of a weather-resistant epoxy resin adhesive, 85-95 parts of weather-resistant resin macadam, 2-4 parts of a reflective thermal insulation material and 0.2-1 part of fibers, wherein the epoxy resin adhesive is prepared by doping quartz sand into an epoxy resin mixture as an external forcephysical thickener. According to the weather-resistant resin permeable pavement provided by the invention, good water permeability of the permeable pavement is guaranteed, the heat conduction coefficient is reduced through a heat insulation layer, the heat insulation effect is achieved, self-cooling can be achieved, the heat island effect is prevented, and the ecological effect of the weather-resistant resin permeable pavement is brought into full play.

Description

technical field [0001] The invention relates to the technical field of road construction, and more specifically relates to a water-permeable pavement material, a preparation method and an application method. Background technique [0002] With the development of social economy and the improvement of people's living standards, a large amount of the earth's surface is covered by buildings and concrete pavement, which makes people's travel more convenient, but at the same time, the impermeable concrete pavement makes the balance of the ecosystem suffer greatly. threaten. For example, in recent years, urban waterlogging has occurred in many cities across the country, and there has been a cry of "come and see the sea". Because the common concrete pavement in the city has no water-permeable and air-permeable effect, this also prevents rainwater from penetrating into the ground in time, causing surface plants to fail to survive due to lack of water resources, and the groundwater le...
