Embodiment Construction

[0018] A kind of asphalt regenerant, prepared by the following components in parts by mass

[0019] Softener 40%-50%,

[0020] 20%~30% plasticizer,

[0021] Performance enhancer 15%~30%,

[0022] 40 parts of softening agent, wherein 10 parts of rapeseed oil, 10 parts of palm oil, and 20 parts of waste lubricating oil are mixed according to mass ratio.

[0023] 21 parts of plasticizer, including 7 parts of C5 / C9 copolymerized petroleum resin, 7 parts of maleic acid resin, and 7 parts of terpene resin are mixed according to mass ratio

[0024] 16 parts of performance enhancer, wherein 8 parts of fatty alcohol polyether amide and 8 parts of dodecyltrimethylammonium bromide are mixed according to the mass ratio.

[0025] After the above components are configured, the preparation steps are as follows:

[0026] Preheat the reaction kettle to 150 degrees; add softener and stir for 6 minutes; add plasticizer and continue stirring for 4 minutes;

[0027] Lower the temperature to 1...

Abstract

The invention discloses an asphalt regeneration agent, wherein the asphalt regeneration agent includes, by mass, 40-50% of a softening agent, 20-30% of a plasticizer, and 15-30% of a performance improver. A preparation method includes steps of: 1) preparing the raw materials according to mass percentage ratio; 2) preheating a reaction kettle to 150-160 DEG C; 3) adding the softening agent, stirring the mixture for 5-8 min, adding the plasticizer according to the mass ratio, and continuously stirring the mixture for 3-5 min; 4) cooling the mixture to 100-120 DEG C and adding the performance improver, stirring the mixture for 2-3 min, and standing and cooling the mixture at normal temperature to prepare the asphalt regeneration agent.

Description

technical field [0001] The invention relates to the field of black pavement aging asphalt regeneration, in particular to an asphalt regeneration agent and a preparation method thereof. Background technique [0002] For black asphalt concrete roads, the asphalt is exposed to the natural environment for a long time, and the oil, colloid, and asphaltene in the asphalt can quickly age when the asphalt is exposed to the natural environment for a long time. It causes irreversible plastic deformation of asphalt, and the indicators such as penetration, softening point, ductility, and viscosity decrease or increase. Even if the properties of the aged asphalt are reversed by asphalt regeneration, it can be restored to the original state to a certain extent, effectively prolonging the service life of the road surface. Currently, hot-mix asphalt regenerants are mostly used on-site. The temperature needs to be controlled between 110-160 degrees, and the mixing is generally 1-2 minutes. ...
