Abstract

The invention relates to the field of road engineering and particularly relates to a novel pavement water-permeable composite material. The pavement water-permeable composite material is mainly prepared from the following raw material components in parts by weight: 80-120 parts of sandstone, 1-10 parts of modified polyurethane and 0.1-1 part of additive. The pavement water-permeable composite material is subjected to filtration and water permeation through micron-order pores on a surface layer so as to ensure that water-permeable holes are not blocked, the skid resistance is good, and functions of water purification and water storage can be realized; and the pavement water-permeable composite material has high strength and good durability and is not easy to discolor. The invention also provides a preparation method of the pavement water-permeable composite material. The method has the advantages that production is carried out at normal temperature, production flows are energy-saving and environment-friendly, production processes are simple, and the cost can be saved.

Description

technical field [0001] The invention relates to the field of road engineering, in particular to a novel pavement permeable composite material and a preparation method thereof. Background technique [0002] With the acceleration of urbanization, cities are covered by more and more impermeable buildings and roads, causing urban heat island effect and increasing the risk of urban flood control. When it rains, the impermeable ground completely prevents the rainwater from infiltrating directly into the ground, and the accumulated water makes it very inconvenient for people to travel; the precious water resources eventually flow away with the drainage pipes, which increases the burden on urban drainage facilities; The large loss of rainwater makes it difficult for the groundwater level to rise, which directly affects the health of urban vegetation, makes it difficult for the surface plants in the city to grow normally, and increases the burden of municipal greening; the large loss...
