Embodiment 1

[0031]A heat regeneration asphalt mixture regeneration agent comprises the following raw materials in parts by weight: 10 parts of dipentene, 10 parts of benzofuran, 5 parts of pine tar, 5 parts of tall oil, 40 parts of heavy oil, 20 parts of of waste lubricating oil, 10 parts of waste engine oil, and 8 parts of biologically active powder; in order to further reduce the impact of volatile harmful substances in the heavy oil, and disperse the heavy oil without affecting the quality of regenerated asphalt, the biologically active powder is, using Alcaligenes faecalis expands and breeds in oily sewage, and the obtained breeding liquid is filtered and dried at low temperature to obtain biologically active powder. The heavy oil is initially hydrolyzed by using the breeding liquid of Alcaligenes faecalis in an alkaline environment. Through protein denaturation, precipitation binds heavy metals in heavy oil; at the same time, the bacteria in the breeding fluid absorb harmful substance...

Embodiment 2

[0039] A heat regeneration asphalt mixture regeneration agent comprises the following raw materials in parts by weight: 10 parts of dipentene, 10 parts of benzofuran, 2 parts of pine tar, 2 parts of tall oil, 30 parts of heavy oil, 10 parts of of waste lubricating oil, 10 parts of waste engine oil, and 2 parts of bioactive powder; all the other formulas and steps are the same as in Example 1.

Embodiment 3

[0041] A heat regeneration asphalt mixture regeneration agent comprises the following raw materials in parts by weight: 20 parts of dipentene, 20 parts of benzofuran, 10 parts of pine tar, 10 parts of tall oil, 60 parts of heavy oil, 30 parts of waste lubricating oil, 20 parts of waste engine oil, 10 parts of bioactive powder; all the other formulas and steps are with embodiment 1.

Abstract

A regenerant for thermal regeneration of an asphalt mixture is provided. Raw materials include, by weight, 10-20 parts of dipentene, 10-20 parts of benzofuran, 2-10 parts of pine tar, 2-10 parts of tall oil, 30-60 parts of heavy oil, 10-30 parts of waste lubricating oil, 10-20 parts of waste engine oil, and 2-10 parts of bioactive powder. The present invention also provides a method for preparingthe regenerant for thermal regeneration of an asphalt mixture. The method comprises the following steps: S1) raw material filtration; S2) preparation of a mixture regenerant prepolymer solution; S3) preparation of a regenerant regulator; and S4) preparation of the mixture regenerant. The beneficial effects of the regenerant and the method are that: the dipentene is utilized to cure a mixed solution, the benzofuran is adopted, the tall oil and the pine tar are then utilized so that the regenerant is convenient to use; the tall oil and the pine tar are not liable to volatilize, and the dipenteneand the benzofuran can reduce the aging rate of asphalt; preliminary hydrolysis is achieved by utilizing Alcaligenes faecalis so as to reduce volatilization of harmful substances; a pH regulator is utilized to reduce the pH, and the fat and oil dispersing ability of petroleum-degrading bacteria is utilized to accelerate preparation of the regenerant.

Description

technical field [0001] The invention belongs to the field of heat-regenerated asphalt mixture preparation, and in particular relates to a heat-regenerated asphalt mixture regeneration agent. Background technique [0002] The prosperity and development of our country's economic level has brought rapid progress in the transportation industry. As the main pavement form of expressways in my country, asphalt pavement has been widely used because of its outstanding road performance, low noise and good flexibility. According to statistics from the construction of roads in our country, by the end of 2012, the mileage of highways that have been repaired and opened to traffic has increased rapidly, reaching 4,237,500 kilometers, of which 96,200 kilometers belong to the mileage of expressways. With the emphasis on transportation facilities, the annual road construction is basically supported by more than 200 billion yuan of national finance; however, the service life of road asphalt p...
