And Asphalt Mixture Experiment regulation " T 0610-2011 in (JTG E20-2011): " asphalt rotating thin-film heat run " preparation
Aged asphalt.See Table 2 for details for regenerative agent basic performance testing result.
Table 2
It can be seen that regenerative agent viscosity prepared by the present invention in 108-125mPa from the testing inspection result of table 1 and table 2
Between s, it is more advantageous to during reclamation of old material and is uniformly merged with waste asphalt and waste asphalt mixture.Embodiment 1-4
In have to recycle environment-friendly type regeneration agent that grease is basic oil preparation compared to traditional light oil regenerative agent it is preferably anti-
Ageing properties.
In addition, energy will be old for the regenerative agent prepared in 1-4 of the embodiment of the present invention from 1 regeneration asphalt Performance Analysis of table
Change pitch and is restored to matrix pitch level.The addition of plasticizer shows the ductility of regeneration asphalt it can be seen from test example 2-3
Writing improves, this is because plasticizer can act at aged asphalt large fragment DNA ligation, macromolecular dispersion and solvation are promoted again
The flexibility and ductility of raw pitch.
(3) the environment-friendly type regeneration agent prepared in the present invention is applicable in high additive, low-dosage waste asphalt mixture.To survey
Regenerative agent prepared by the present invention is tried to the power of regeneration of waste asphalt mixture, mixture performance test uses 20%, 60%

The regenerative agent of middle preparation prepares reclaimed asphalt mixture and carries out analysis of experiments；See Table 3 for details for the performance indicator of reclaimed asphalt mixture.
Table 3
From table 3 it can be seen that the dynamic stability of reclaimed asphalt mixture is all larger than specification and wants in embodiment 1-2, test example 1
800 times/the mm asked.From the point of view of comparing three kinds of reclaimed asphalt mixtures, the reclaimed asphalt mixture embodiment under identical old material volume
The dynamic stability of 1-2 is slightly below reclaimed asphalt mixture test example 1, illustrates the Rut resistance of reclaimed asphalt mixture test example 1
Ability is preferable, but also illustrates that the regeneration effect of waste asphalt mixture in test example 1 is poor simultaneously.Old material volume is 20% He
Reclaimed asphalt mixture immersion residual stability when 60% is able to satisfy the immersion residual of plain asphalt mixture as defined in specification
Stability is greater than 80% requirement.And the immersion residual stability of mixture in embodiment, freeze-thaw split intensity ratio compared to
Reclaimed asphalt mixture in test example wants high, illustrates the regeneration effect to regenerative agent in embodiment to reclaimed asphalt mixture
It is better than regenerative agent in test example.
