Description

A kind of preparation method of the special microporous permeable material of pavement paving
Technical field
The present invention relates to a kind of preparation method of the special microporous permeable material of pavement paving, belong to urban architecture Technical field of material.
Background technology
In the process of construction in existing city, the waterproof pavement such as a large amount of cement concretes, bituminous concrete, although improve Traffic and road conditions, but these waterproof pavements also cause or exacerbated the occurrence and development of Urban Ecological Problems.
In order to alleviate these phenomenons and further improve the trip condition of people, relevant person energetically researchs and develops various The water-permeable pavement material of type, and it is applied to the ground pavements such as pavement, public square, open parking ground.Wherein, should With most extensively, research more deep mainly macrovoid cement pervious concrete and pitch pervious concrete.Theirs pours Technique is simple, cost is low, but water-permeable passage, i.e. aggregate accumulate the macroporous structure to be formed easily by the tiny of extraneous dust etc Particle is blocked, and is made permeable effect reduction or even is lost, it is necessary to high pressure water washing or vavuum pump dust suction, for the road surface of large area For, safeguard inconvenient, and maintenance cost is higher, also there is that many seepy material holes are tiny, compact structure, wearability is good, such as Ceramic water-permeable brick, but their complex manufacturing are sintered, some high-grade locations are only used for, and in the making of ceramic water-permeable brick During need high temperature sintering, consume mass energy.
Therefore, a kind of cost of developmental research is low, easy to maintenance, and hole is small, compact structure, the good microporous permeable of wearability Material, is following developing direction of urban road construction material.
The content of the invention
The present invention solves the technical problem of：For traditional pervious concrete in use, pore structure is easy It is blocked, causes permeable effect to decline, and it is difficult in maintenance, and there is provided a kind of pavement paving for the problem of maintenance cost is high The preparation method of special microporous permeable material.
