Embodiment 1
[0026] A kind of colored asphalt suitable for cold regions, the specific operation of the preparation process is:
[0027] (1) Pour the naphthenic oil into the reaction container, place it on an electric furnace and heat it to 100°C, and keep stirring slowly and at a constant speed during the heating process to keep the naphthenic oil evenly heated;
[0028] (2) Continue heating. When the temperature rises to 125°C to 135°C, add the hydrogenated C9 petroleum resin in two times, and keep stirring at a constant speed during the heating process to ensure that the mixture is heated evenly, and promote the melting of the hydrogenated C9 petroleum resin and its interaction with the environment. Physical blending of alkanes;
[0029] (3) After the hydrogenated C9 petroleum resin is completely melted, add EVA, continue heating, control the reaction temperature at 140°C to 150°C, and promote the melting of EVA and its blending with naphthenic oil and hydrogenated C9 petroleum resin;

Abstract
The invention discloses colored asphalt suitable for cold regions and a preparation method of the colored asphalt, and belongs to the field of technical materials used in road engineering. The coloredasphalt is prepared from the following raw materials: naphthenic oil, hydrogenated C9 petroleum resin, SBS, EVA and epoxidized soybean oil (ESO). The naphthenic oil with small molecular weight is used as an aromatic component and a saturated component in the colored asphalt; the hydrogenated C9 petroleum resin, the SBS and the EVA components are used as asphaltene and colloid in the colored asphalt; the epoxidized soybean oil is used for blending the colored asphalt, so that a colloid system with properties similar to those of asphalt is simulated. The colored asphalt prepared by the method has excellent low-temperature performance, is far superior to common colored asphalt, and can completely meet the application requirements of cold regions. All adopted raw materials are green materials, are non-toxic and harmless and are beneficial to environmental protection. The colored asphalt and a mixture thereof can be used for paving surface layers of various grades of roads in cold regions.
Description
technical field [0001] The invention belongs to the field of technical materials used in road engineering, and relates to colored asphalt suitable for cold regions and a preparation method thereof. Background technique [0002] As a new type of road surface, colored asphalt pavement can be paved in different colors according to actual needs, which can improve the road environment, guide the driver's sight, relieve driving fatigue, improve road comfort and safety, and is also conducive to environmental protection. At present, it has been applied to a certain extent at home and abroad. However, the climatic conditions in cold regions put forward strict requirements on the road performance of colored asphalt and its mixture, especially the low-temperature performance. It is difficult to meet the application requirements in severe cold regions.
