Description
Technical field
The present invention relates to a kind of novel pavement environment-friendly materials, and in particular to a kind of infiltration road surface with air-cleaning function
And preparation method thereof.
Background technology
With the development of urbanization process, the pace of construction in city is accelerated, and the ecological environment in city bears huge pressure.
The earth's surface of modern city is gradually hardened by material water-proof materials such as building and concrete and covered, " the artificial sand formed on ecology
It is unconcerned ".Great negative effect is brought to the ecological environment in city in these fluid-tight road surfaces.Therefore, how in urban construction
Realize that environmental protection attracts people's attention with economic, society harmonious development.City water resource is supplemented, to improving business economic
Benefit, raising are safely, preserving the ecological environment has great economic and social benefit.
At present, have begun to build more infiltration road surfaces to solve the problems, such as city water resource shortage.But existing skill
Infiltration road surface in art use it is mostly be it is single with gathering materials, do not have to or it is few with fine aggregate prepare without sand, celluar concrete.Road
The porosity in face becomes big compared with conventional pav, is easy to seep water.But porosity change causes intensity to be deteriorated greatly, so most of water seepage roads
Face is suitable only for bicycle lane or pavement.Therefore, the water seepage road face for building high intensity has good social effect.The Black Warrior
Rock fiber shows the compatibility better than other reinforcing fibers to cement matrix or stone material as a kind of active material.Cement
As a kind of fragile material, substantial amounts of hole and crack are internally easily formed with surface during cast and maintenance, so as to
Influence every mechanical property of base material.And cement matrix can be significantly reduced using basalt fibre as cement reinforcements
Hole and crack.This is due to that matrix load fibers can prevent the expansion in crack and can absorb the energy of crackle, so that
Every mechanical property of cement matrix is improved.Therefore, it is using the binding of basalt fibre and existing infiltration road surface
It is very important.
Meanwhile also in the presence of a severeer environmental problem, that is, the various motor vehicles travelled on road surface contribute to sky
VOC (the volatile organic of most haze (PM2.5) and various harm inside gas pollutant
Compounds, abbreviation VOC).These gases and particulate pollutant can cause greatly to injure to the body and psychology of people.Therefore,
Certain solution is provided on road surface, the technical research adsorbed and degraded to pollutant within the very first time also right and wrong
It is often important.
Therefore, it is badly in need of providing the technical side of a kind of infiltration road surface with air-cleaning function and its methods for making and using same
Case.
