Special multifunctional prefabricated pavement brick

Abstract

The invention discloses a special multifunctional prefabricated pavement brick. The special multifunctional prefabricated pavement brick sequentially comprises a concrete plate body layer, a sticky layer, a light-emitting functional layer and a tail gas absorbing functional layer from bottom to top, wherein the concrete plate body layer is made of fiber concrete; the sticky layer is made of modified emulsified asphalt or resin material; the light-emitting functional layer is a graded light-emitting broken stone layer which is composed of a colorless cementing material and graded light-emitting broken stones; and the tail gas absorbing layer is made of anatase type nano silicon dioxide powder which synchronously spreads on the light-emitting function layer. The special multifunctional prefabricated pavement brick disclosed by the invention has the night light-emitting function and the function of absorbing automobile tail gas, realizes the purpose of absorbing and degrading automobile tail gas in daytime and emitting light at night; and through a prefabricating mode, the effect of the special multifunctional prefabricated pavement brick is sufficiently brought into play, the use is convenient and the practicability is high.

Description

technical field [0001] The invention belongs to the field of road engineering, and relates to a functional material for road construction, in particular to a special brick for multifunctional prefabricated road surface. Background technique [0002] In recent years, with the rapid development of the road industry, more and more functional road construction materials have emerged. [0003] In some poorly illuminated sections of urban roads, luminous pavement is used, which not only adds a beauty to the city night scene, but also has the function of lighting. At present, luminescent road materials are mostly used in the way of adding luminescent material to paint or spraying luminescent powder, and now there are also applications for embedding luminescent gravel. For luminescent materials in the form of coatings, the road performance of the matrix coating itself will directly affect the performance of the luminescent materials. In the prior art, road coatings generally have p...
