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 diseases due to the influence of natural factors such as ultraviolet rays and rain. Using ordinary asphalt for repairs will cause damage due to color differences. And cause dazzling pollution, using general hot-mix colored asphalt to repair will cause waste of resources because of heat treatment every time and the amount of use is small, and the use of general hot-mix colored asphalt needs to be sealed for a long time after construction The operation area has seriously affected the traffic; therefore, there is an urgent need for a low-cost, easy-to-use, non-affecting traffic during construction, and can maintain the same color and adhesive properties as the colored pavement at room temperature.

Embodiment 1

[0026] The raw materials used in the production of 106kg normal temperature colored pavement cold patch are as follows:

[0027]

[0028] Its preparation process is as follows:

[0029] ① Preparation of material A: first clean up the stirring equipment, and then add furfural extraction oil with a weight of 2.23kg, styrene-butadiene-styrene block copolymer with a weight of 0.18kg, and a weight of 2.00kg Petroleum resin with a weight of 0.45kg of inorganic pigments. During the addition process, the stirring equipment kept stirring, and the above mixture was heated to 170°C. After stirring at 170°C for 60 minutes, 4.86kg of cement was prepared by shearing A material;

[0030] ② Preparation of material B: mix 0.11kg of solvent oil and 0.006kg of Na 2 SO 3 1-aminoethyl-2-heptadecylimidazoline with a weight of 0.004 is mixed and stirred to make 0.12kg modified solution B material, as a lubricant and a modifier;

Abstract

The invention discloses a constant-temperature colored pavement cold repair material and a preparation process thereof. The cold repair material is prepared by blending a constant-temperature colored pavement cold repair binding material and dried stone according to a weight ratio of 6:100, wherein the constant-temperature colored pavement cold repair binding material is prepared by uniformly mixing a material A, a material B and a material C according to a weight ratio of 81:2:17; the material A is prepared from the following components in parts by weight: 50-55 percent of furfural extract oil, 3-4 percent of styrene-butadiene-styrene block copolymer, 37-45 percent of petroleum resin and 8-10 parts of inorganic pigment; the material B is prepared from the following components in parts byweight: 92 parts of solvent oil, 5 parts of Na2SO3 and 3 parts of 1-aminoethyl-2-heptadecylimidazoline; and the material C is diesel oil. The cold repair material has the advantages of low cost, convenience in use, no influence on traffic during construction and capability of keeping the same color and binding material property as the colored pavement.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a normal-temperature cold patch for colored pavement that can maintain the same color and properties of the adhesive as that of the colored pavement and its preparation process, which is used in the process of road engineering treatment of pits and troughs on colored pavement . 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 lay municipal roads and community roads. However, with the long-term use of colored asphalt pavement, the road surface will have pits and other diseases due to the influence of natural factors such as ultraviolet rays and rain. ...
