Title:
REGENERATION OF RECOVERED ASPHALT
Document Type and Number:
Japanese Patent JP2018035352
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a recovered asphalt composition and a regeneration method thereof by aliphatic acid ester derived from tall oil.SOLUTION: There are provided an asphalt composition containing recovered asphalt and an ester functional regenerant derived from tall oil, and a composition which reactivates desired properties of unused asphalt to the recovered asphalt by a regeneration binder composition, provides improvement of low temperature crack resistance of the asphalt by reduction of glass transition initiation temperature and improvement of creep rigidity and has good fatigue crack resistance and resistance to track digging. There is provided the composition where the regenerant is selected from trimethylol propanethalate, ethylene glycol monomerate, neopentyl glycol monomerate, 2-ethylhexyl monomerate and glycerol monomerate. There is provided a method for reducing level with which construction industry depends on unused materials which cannot be regenerated, where the regenerant reduces a temperature needed for compaction or mixing of the asphalt composition, energy is saved and cost is reduced.SELECTED DRAWING: None
