Abstract

The invention provides a permeable pavement with an air purifying function and a preparation method thereof. The permeable pavement comprises an upper layer pavement and a lower layer pavement. Raw materials of the upper layer pavement comprise, by weight, 5-95 parts of coarse aggregate, 1-5 parts of basalt fiber, 1-10 parts of a polymer adhesive, 1-5 parts of a coloring agent and 1-5 parts of an air purifying material. Raw materials of the lower layer pavement comprise, by weight, 1-20 parts of an inorganic adhesive, 1-90 parts of coarse aggregate, 1-5 parts of basalt fiber and 8-25 parts of water. By means of the prepared permeable pavement, the removal rates of formaldehyde, PM2.5 and nitrogen oxides within 24 hours are above 65%, 45% and 90% separately.; and the compressive strength of the pavement within 28 days can reach above 50MPa, and the permeable capacity reaches above 200L/(m2.min). The technology is simple and easy to operate, the raw materials are low in cost, and the permeable pavement is suitable for industrialized production.

Description

technical field [0001] The invention relates to a novel pavement environmental protection material, in particular to a water seepage pavement with air purification function and a preparation method thereof. Background technique [0002] With the development of the urbanization process, the pace of urban construction is accelerating, and the ecological environment of the city is under tremendous pressure. The surface of modern cities is gradually hardened and covered by water-blocking materials such as buildings and concrete, forming an ecological "artificial desert". These impermeable pavements have a great negative impact on the ecological environment of the city. Therefore, how to realize the harmonious development of environmental protection and economy and society in urban construction has aroused people's attention. Supplementing urban water resources has significant economic and social benefits for improving the economic benefits of enterprises, improving safety, and...
