[0004] At present, the preventive maintenance methods of asphalt pavement mainly adopt micro-surface treatment and slurry sealing layer. These methods can not only form a sealing layer on the pavement, resist the damage caused by the penetration of water or other chemicals, but also better restore the use function of the pavement , but it also has shortcomings: a. The sealing layer simply covers the surface of the pavement. When the temperature changes, it is inconsistent with the expansion and shrinkage of the old asphalt pavement, which eventually leads to cracks in the pavement; b. Need to design and prepare asphalt Mixed materials, the process is cumbersome, and special machinery and equipment are required for construction; c. The cost is high and the cost performance is low

[0021] The above raw materials are operated according to the following steps: add coal tar and toluene to the reaction kettle under stirring conditions, heat up to 60°C after stirring for 8 minutes, add No. 104 acrylic resin, and add rapid penetrant T and furfural to extract the oil after stirring for 8 minutes. After continuing to stir for 30 minutes, cool down to room temperature, and the obtained liquid mixture is the asphalt pavement penetration regeneration paint.
[0024] The above raw materials are operated according to the following steps: Add coal tar and toluene into the reaction kettle under stirring conditions, heat up to 70°C after stirring for 10 minutes, add No. 105 acrylic resin, and add penetrant JFC-M and furfural to extract the oil , continue to stir for 30 minutes, then cool to room temperature, and the resulting liquid mixture is the asphalt pavement penetration regeneration paint.
[0027] The above raw materials are operated according to the following steps: Add coal tar, kerosene, and phenyl glycidyl ether No. 690 into the reaction kettle under stirring conditions, stir for 15 minutes and then raise the temperature to 80°C, add No. 2080 acrylic resin, and stir for another 15 minutes. Penetrant T, penetrant JFC-E, and furfural extract the oil, continue to stir for 30 minutes, and then cool to room temperature. The resulting liquid mixture is the asphalt pavement infiltration regeneration coating.

Abstract
The invention discloses a penetrable regeneration paint for an asphalt pavement and a preparation method of the penetrable regeneration paint, which belong to the technical field of preparation of a preventative maintenance material for the asphalt pavement. The regeneration paint is a liquid mixture at normal temperature and particularly comprises the following components in part by weight: 30 to 50 parts of film forming resin, 3 to 9 parts of penetrant, 2 to 8 percent of asphalt rejuvenate agent, 30 to 50 parts of solvent and 10 to 20 parts of coal tar. The penetrable regeneration paint for the asphalt pavement, which is prepared by the preparation method, can strongly permeate through the asphalt pavement to deeply reduce aged asphalt so as to form a novel protective layer without carrying out mixture overlaying on the original pavement, and the using function of the pavement is recovered only by recovering the activity of the aged asphalt; meanwhile, a sealing film is formed on the asphalt pavement so as to prevent water, gasoline, chemicla and the like from invading into the asphalt pavement. When being adopted to recover the using function of the pavement, the penetrable regeneration paint for the asphalt pavement has the advantages that the penetrable regeneration paint is simple to construct and has short time of closing traffic and good waterproof performance; and the pavement friction coefficient is not reduced or reduced little.
Description
technical field [0001] The invention belongs to the technical field of preparation of asphalt pavement preventive maintenance materials, and in particular relates to an asphalt pavement permeable regeneration coating and a preparation method thereof. Background technique [0002] Asphalt pavement has the advantages of smooth surface, comfortable driving, wear resistance, low vibration, low noise, short construction period, easy maintenance and repair, etc. It has been widely used on urban and rural roads, especially high-grade roads. However, after a certain number of years of use of the asphalt pavement, due to the combined effects of traffic loads and natural factors, the asphalt in the surface layer will gradually age, which will eventually lead to the appearance of various diseases such as network cracks, subsidence, rutting, and bagging. The service function of the pavement. [0003] The maintenance methods of asphalt pavement can be mainly divided into two categories:...
