Problems solved by technology

Due to the short mixing time, it is difficult for the regenerant to quickly penetrate into the aged asphalt, so that it cannot effectively function, and the recovery effect on the performance and structure of the aged asphalt is poor; the waste asphalt cannot be effectively regenerated, and the pavement performance of the regenerated asphalt mixture is poor.

preparation example Construction

[0024] A preparation method of high-permeability asphalt regenerant comprises the following steps:

[0025] Mix light base oil, plasticizer and anti-aging agent, shear and stir evenly at 130-150°C, then cool naturally to room temperature, then add structure repair agent and penetrating agent, keep warm and stir evenly to obtain high permeability type asphalt regenerant.

[0026] The stirring speed during the shear stirring process is 500-800 r / min.

[0027] The temperature during the heat preservation and stirring process is 100° C., and the stirring speed is 300-500 r / min.

Embodiment 1

[0029] The specific operation process of this embodiment is:

[0030] (1) Preparation of high-permeability asphalt regenerant

[0031] First, mix light base oil, plasticizer and anti-aging agent, and stir for 1 hour with a high-speed shearing machine at 150°C. The stirring speed of the high-speed shearing machine is 800r / min; naturally cool the above mixed solution to room temperature ;Keep the temperature at 100°C, add structure repairing agent and penetrating agent to the mixture, and then continue to stir for 1 hour at a speed of 300-500r / min; cool to room temperature to obtain a high-permeability asphalt rejuvenator.

[0032] Among them, the technical requirements of various raw materials in the preparation process of the above-mentioned high-permeability asphalt rejuvenator are shown in Table 1.

Abstract

The invention discloses a high-permeability asphalt regenerant and a preparation method thereof. The regenerant comprises, in percentage by mass, 76.64% of light base oil, 0.93% of a penetrant, 5.61% of a structure repairing agent, 11.21% of a plasticizer and 5.61% of an anti-aging agent. The regenerant achieves effective regeneration of waste asphalt and is good in pavement performance, and the preparation method is simple.

Description

technical field [0001] The invention belongs to the field of regeneration and recycling of road engineering materials, and relates to a high-permeability asphalt regeneration agent and a preparation method thereof. Background technique [0002] Under the comprehensive action of traffic load, environment and natural factors, asphalt pavement will have rutting, cracks, water damage, looseness, oil flooding and other diseases, and gradually aggravate with the increase of service time until it loses its function. Asphalt pavements generally require large-scale repairs or renovations before their useful life. According to the actual use of the asphalt pavement, it generally needs to be refurbished once in about 10 years, that is, to remove the old asphalt pavement and then re-pave the new asphalt pavement. According to statistics, China produces more than 2 million tons of waste asphalt mixture every year, including more than 100,000 tons of asphalt. It is speculated that as th...
