Abstract

The invention relates to a spraying type colored asphalt, a preparation method and a use method thereof. The spraying type colored asphalt is prepared from the following raw materials by weight: 30-50parts of a softening agent, 10-20 parts of a styrene-butadiene-styrene triblock copolymer, 40-50 parts of a plasticizer and 70-90 parts of a solvent, wherein the solvent comprises an ester solvent and/or an alkane solvent. According to the spraying type colored asphalt provided by the invention, toxic and harmful solvents containing benzene and the like are not needed, an ester solvent and/or analkane solvent are/is used, can well dissolve a softener, SBS and a plasticizer, is harmless to the human body, can be directly sprayed on a pavement, also the product has low viscosity, is convenientto construct, can realize short-term color recovery of a colored asphalt pavement and repair of tiny cracks, and also has relatively high adhesive property.

Description

technical field [0001] The invention relates to the technical field of road asphalt, in particular to a spray-type colored asphalt, a preparation method and a use method thereof. Background technique [0002] As a new pavement technology, colored asphalt concrete pavement is used more and more in places such as highways, roads or squares, which has aroused people's widespread interest and attention, and is regarded as a "new green building material" by the global engineering community. For a long time, road pavement has only two colors, black (asphalt pavement) and white (cement pavement). With the development of the economy, colored asphalt pavement with rich colors and excellent performance has gradually begun to be popularized. Colored asphalt has the functions of decorating roads and beautifying the urban environment. It is applied to different functional sections or lanes (such as bus lanes, warning roads, park roads, non-motorized lanes, parking spaces, landscape road...
