Problems solved by technology

[0003] Colored asphalt is generally used to lay municipal roads and community roads. However, with the long-term use of colored asphalt pavement, the road surface will have pits and other phenomena due to the influence of natural factors such as ultraviolet rays and rain.
For the repair of potholes, the use of ordinary asphalt for repair will cause dazzling pollution due to the difference in color. When using general hot-mix colored asphalt mixture for repair, heat treatment must be done every time and the amount used is small, which will pollute the environment and Caused the waste of resource, general hot-mix type colored asphalt mixture is in construction, and the area that repaired has been closed for a long time, has greatly influenced traffic, therefore, urgently needs a kind of low cost at present, easy to use, Environment-friendly color pavement cold patching material and its preparation process that are environmentally friendly, do not affect traffic during construction, and can maintain the same color and adhesive properties as the colored pavement

Abstract

The invention discloses an environment-friendly color pavement cold-patching material and a preparation technology thereof. The preparation technology comprises the following steps of uniformly mixing a pigment and dried stone materials according to a weight ratio of 2: 100, adding an environment-friendly color pavement binder into the mixture according to a weight ratio of the environment-friendly color pavement binder to the dried stone materials of 10: 100, and mixing. The environment-friendly color pavement binder is prepared by mixing 60-70wt% of a material A and 30-40wt% of a material B and carrying out shearing of the mixture by a colloid mill, wherein the material A is obtained by mixing 50 to 55wt% of furfural extract oil and 45 to 50wt% of petroleum resin; and the material B is obtained by mixing 3 to 4 parts by weight of N-alkyl-triethyl-tertiary amine, 6 to 8 parts by weight of cationic SBS latex, 8 parts by weight of Na2SO3, 6 parts by weight of 1-aminoethyl-2-heptadecylimidazoline and 74 to 77 parts by weight of water. The environment-friendly color pavement cold-patching material has a low cost, is convenient for use, does not influence traffic during construction, and has a color and binder properties the same as a color and binder properties of a color pavement needing to be repaired.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to an environment-friendly colored pavement cold patching material which is used in the process of road engineering treatment of pits and other diseases on the colored pavement and can maintain the same color and binder properties as the colored pavement. Its preparation process. Background technique [0002] With the development of my country's economic construction, colored asphalt has entered the stage of experimentation and promotion in my country. Many cities have tried to use colored asphalt concrete to lay urban roads, such as Shanghai, Beijing, Tianjin, Changsha, Shenyang and Xiamen. [0003] Colored asphalt is generally used to pave municipal roads and community roads. However, with the long-term use of colored asphalt pavement, the road surface will have pits and other phenomena due to natural factors such as ultraviolet rays and rain. For the repair ...
