Problems solved by technology

[0005] At present, the role of Sasobit, the mainstream asphalt warm mix agent in China, has been proved in practical applications. The viscosity reduction of the binder in the high temperature area is somewhat insufficient. For this reason, we adopt the SC composite warm mixing agent technology. The research shows that the SC composite warm mixing technology has a very obvious effect on reducing the viscosity of the high-viscosity material such as the colored binder in the high temperature area.

Embodiment 1

[0028] Example 1: A colored asphalt warm mix agent is prepared by mixing and melting 48 kg of polyethylene wax, 48 kg of calcium stearate, and 4 kg of silicon dioxide, extruding and granulating.

[0029] The preparation process of the colored asphalt warm mix agent is as follows: first clean the mixing and stirring equipment, and then add 48 kg of polyethylene wax, 48 kg of calcium stearate, and 4 kg of silicon dioxide to the mixing equipment through the feeding pipeline After being heated to 140°C, it is extruded and granulated through a plastic extrusion granulator.

[0030] The process of using the colored asphalt warm mix agent to prepare warm mix asphalt mixture is as follows: first mix 100 kg of Add colored asphalt into the mixing equipment, heat to 170°C, start strong stirring, then add 4 kg Color asphalt warm mix agent, just mix for 30 minutes.

Embodiment 2

[0032] A colored asphalt warm mix agent is prepared by mixing and melting 48kg polyethylene wax, 49kg calcium stearate and 3kg silicon dioxide, extruding and granulating.

[0033] The preparation process of the colored asphalt warm mix agent is as follows: first clean up the mixing and stirring equipment, then add 48kg of polyethylene wax, 49kg of calcium stearate, and 3kg of silicon dioxide into the mixing equipment through the feeding pipeline, and heat After reaching 140°C, pass through a plastic extrusion granulator, extrude and granulate.

[0034] The process of using the colored asphalt warm mix agent to prepare warm mix asphalt mixture is as follows: first mix 100 kg Add colored asphalt into the mixing equipment, heat to 170°C, start strong stirring, and then add 6 kg Color asphalt warm mix agent, just mix for 30 minutes.

Embodiment 3

[0036] A colored asphalt warm mix agent is prepared by mixing and melting 49kg of polyethylene wax, 49kg of calcium stearate and 2kg of silicon dioxide, extruding and granulating.

[0037] The preparation process of the colored asphalt warm mix agent is as follows: first clean the mixing and stirring equipment, and then add quantitative polyethylene wax, calcium stearate, and silicon dioxide to the mixing equipment through the feeding pipeline, and heat it to 140°C , through a plastic extrusion granulator, extruded and granulated.

[0038] The process of using the colored asphalt warm mix agent to prepare warm mix asphalt mixture is as follows: first mix 100 kg Add colored asphalt into the mixing equipment, heat to 170°C, start strong stirring, and then add 6 kg Color asphalt warm mix agent, just mix for 30 minutes.

Abstract

The invention relates to a color asphalt warm-mixing agent, in particular relating to a preparation process of a warm-mixing agent for color asphalt. The color asphalt warm-mixing agent is prepared by mixing, melting, extruding and granulating the following components by weight percent: 48-48% of polyethylene wax, 48-49% of calcium stearate and 2-4% of silica. The color asphalt warm-mixing agent has the advantages that the construction cost is saved, and the construction temperature is reduced.

Description

technical field [0001] The invention relates to an asphalt warm mix agent, in particular to a preparation process for a warm mix agent for colored asphalt cement. Background technique [0002] At present, colored asphalt has entered the stage of experimentation and promotion in my country, and many cities have tried to use colored asphalt concrete to pave urban roads, such as Shanghai, Beijing, Tianjin, Changsha, Shenyang and Xiamen. [0003] The production process of colored asphalt mixture is basically the same as that of general asphalt mixture, the difference is that the materials processed on each process route have changed, the filler is changed to pigment, the aggregate is changed to colored stones, and the binder is changed to It is changed to translucent cementitious material, which is processed into colored asphalt mixture through traditional technology. There are many colors of colored asphalt mixture, but generally red, yellow and green are the main colors, and ...
