Technical Field
The invention relates to the technical field of asphalt regenerants, in particular to a dispersed SBS modified asphalt mixture regenerant and a preparation method thereof.
Background
The regeneration of bitumen is the reverse of aging. Typically, a rejuvenating agent such as corn oil, lubricating oil, etc. may be incorporated. After the regenerant is doped, the relative content of the asphaltene is reduced, the dissolving capacity of the soft asphaltene to the asphaltene is improved, the compatibility of the asphalt is improved, and the penetration degree and ductility of the asphalt are improved, so that the original performance of the asphalt is recovered or is close to the original performance.
The asphalt regeneration mechanism has two theories, one theory is a compatibility theory, the theory starts from chemical thermodynamics, and the reason for aging of asphalt is considered to be that the compatibility of each component in an asphalt colloid system is reduced, so that the solubility parameter difference among the components is increased. If a certain regenerant can be added to reduce the difference of solubility parameters, the asphalt can recover (even exceed) the original properties. The other theory is "composition adjustment theory". The theory starts from the migration of chemical components, and the theory is that due to the migration of the components, after asphalt is aged, some components are more, some components are less, and the proportion of the components is not consistent, so that the performance of an asphalt pavement is reduced, and if the components are adjusted by adding a regenerant, the original properties of the asphalt can be recovered. In fact, these two theories are consistent, the former being explained by the chemical energy of the internal structure of the bitumen and the latter being explained by the macroscopic chemical composition.
