Embodiment 1

[0015] The preparation method of colored asphalt pavement mixture comprises the following steps:

[0016] First heat 20kg of aromatic oil to 160°C, then add 15kg of aliphatic resin C5, 10kg of terpene resin, 2kg of styrene-butadiene-styrene block copolymer (SBS) and stir for 2 hours, then cool down to 120°C, then Add 15kg of polyol (such as 1,2-propanediol) and stir for 1h, and finally add 1kg of iron red pigment and stir for 1h as needed to obtain the product.

Embodiment 2

[0018] The preparation method of colored asphalt pavement mixture comprises the following steps:

[0019] First heat 40kg of heavy oil to 180°C, then add 40kg of aromatic resin C9, 25kg of terpene resin, 10kg of powdered styrene-butadiene rubber (SBR) and stir for 2 hours, then cool down to 140°C, then add 15kg of polyether and stir for 2 hours, and finally according to Need to add 15kg iron green pigment and stir for 1 hour to get the product.

Embodiment 3

[0021] The preparation method of colored asphalt pavement mixture comprises the following steps:

[0022] First heat 30kg distillate oil to 170℃, then add 10kg aromatic resin C9, 20kg aliphatic resin C5, 20kg terpene resin, 4kg powdered styrene-butadiene rubber (SBR), 4kg styrene-butadiene-styrene block Stir the copolymer (SBS) for 2 hours, then lower the temperature to 130°C, then add 25kg of ethyl acetate and stir for 2 hours, and finally add 10kg of chrome green pigment and stir for 1 hour to obtain the product.

Abstract

The invention relates to a coloured asphalt pavement mixture. The coloured asphalt pavement mixture is prepared from the following raw materials in parts by weight: 20-40 parts of base oil, 15-40 parts of petroleum resin, 10-25 parts of terpene resin, 2-10 parts of a modifying agent, 1-15 parts of inorganic pigment and 15-30 parts of a pressure-sensitive diluent. The coloured asphalt pavement mixture only needs to be simply packaged in barrels or a tank car in transportation and can be mixed and used with stones at normal temperature without being heated before and after use, and then pavement spreading and roller compaction construction are carried out, so that a preparation process of the coloured asphalt pavement mixture is greatly simplified, and the construction of a coloured pavement is changed to be extremely simple and convenient. The coloured asphalt pavement mixture has pressure-sensitive property and is subjected to roller compaction by virtue of a road roller and transit vehicles, the bonding strength between asphalt and aggregate is improved, and the self strength of the mixture is improved.

Description

(1) Technical field [0001] The invention relates to a cold construction colored pressure-sensitive modified asphalt, in particular to a colored asphalt pavement mixture. (2) Background technology [0002] In recent years, the state has focused on improving urban functions, improving the living environment, continuing the urban context, enhancing urban taste, beautifying the urban landscape, and highlighting urban characteristics. It has continuously improved the level of landscaping planning, construction, and management. At the same time, strive to promote the harmonious development of people and the environment to further enhance the city's taste. As a part of urban construction, roads should be more beautified. And now generally adopt colored asphalt to pave the road, but need to heat repeatedly in the existing colored asphalt use process, have a strong impact on its use effect, need to improve. (3) Contents of the invention [0003] In order to make up for the defici...
