Aged-asphalt regeneration agent, regenerated asphalt mixture and preparation method of two
The invention discloses an aged-asphalt regeneration agent, and the agent comprises the following compositions in percent by mass: 40-60% of a softening agent, 20-30% of a tackifier, and 15-30% of a performance improver. The aged-asphalt regeneration agent is good in compatibility with aged asphalt, and is capable of substantially adjusting the viscosity of aged asphalt, enabling aged asphalt to have good rheological property and realizing the purpose of improving performances of aged asphalt. By applying the aged-asphalt regeneration agent to prepare the regenerated asphalt mixture, efficient utilization of waste asphalt mixture is realized, and also the prepared regenerated asphalt mixture is excellent in various performances, and possesses the Marshall stability of 10 KN or more, the splitting tensile strength of 1.0 MPa or more and the dynamic stability of 3600 times mm. Usage of stone and new asphalt is effectively saved, cost is reduced, and the regenerated asphalt mixture is suitable for popularization and application.
