Problems solved by technology

The colored asphalt binder provided by the invention is a hot-mix asphalt material, which also has the problems of high repair cost and low construction efficiency
[0006] Generally speaking, the colored asphalt pavement has the disadvantages that the color is not easy to maintain and clean, the existing methods are slow in construction, high in cost, and insufficient in performance. At present, there is no effective maintenance method. High-performance, short-term open traffic, low-cost new materials, can realize the short-term restoration of color of the old colored asphalt pavement, repair of small cracks and other functions

Abstract

The invention relates to a spray-type colored asphalt and its preparation method and use method. The preparation raw materials of the spray-type colored asphalt include the following components in parts by weight: 30-50 parts of softener, styrene-butadiene-benzene 10-20 parts of ethylene tri-block copolymer, 40-50 parts of plasticizer, and 70-90 parts of solvent; the solvent includes ester solvent and / or alkane solvent. The spray-type colored asphalt provided by the present invention does not need to use toxic and harmful solvents such as benzene, but uses ester solvents and / or alkane solvents, which can dissolve softeners, SBS and plasticizers well, and are not harmful to the human body. It is harmless and can be directly sprayed on the road surface. The product has low viscosity and is easy to construct. It can restore the color of the colored asphalt pavement and repair tiny cracks in a short period of time, and has high bonding performance.

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...
