Abstract

The invention relates to a paving material and an environment-friendly easy-drainage porous pavement structure prepared through the paving material. The paving material is prepared from 1,300-1,500 kg of a component A, 300-450 kg of a component B and a component C, and the ratio of the component C to the component B is 0.28-0.32. The component A is prepared from, by mass, 4-6 parts of building stone, 3-5 parts of waste concrete particles and 1-2 parts of rubber particles. The component B is prepared from, by mass, 8.5 parts of cement, 0.5 part of basalt fibers and 1 part of coal ash. The component C is prepared from, by mass, 2.92-2.96 parts of water and 0.04-0.08 part of a water reducing agent. Compared with the prior art, the pavement structure prepared through the paving material has the beneficial effects of being good in drainage, resistant to freeze thawing and good in durability; and due to a waterproof layer, a concrete layer and a cement stabilized macadam layer can be prevented from being infringed by the natural environment and chemical objects, and the pavement durability is improved.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a pavement material and an environment-friendly and easily drainable permeable pavement structure prepared by the same. Background technique [0002] With the rapid development of my country's economy, environmental problems are becoming more and more severe, and the output of various wastes has increased sharply. Recycling wastes is an important way to protect natural resources and promote sustainable development. The acceleration of urban construction in our country has led to a rapid increase in the output of waste concrete. At present, the annual waste concrete produced in my country has reached about 100 million tons, and the long-term accumulated waste concrete will reach billions of tons. In 2015, the amount of waste tires produced in my country reached 330 million, and the recycling rate was less than 50%. Both waste concrete and waste tires can be r...
