The performance test results of plant oil base bitumen regenerant prepared by embodiment 1.1 to embodiment 1.13 such as 1 institute of table Show.
The performance test results of 1 plant oil base bitumen regenerant of table
The stability result of plant oil base bitumen regenerant in embodiment 1.1-1.13 is as shown in Figure 1, can be with from Fig. 1 Find out, the stability of vegetable oil regenerative agent is very good, can stablize preservation, is not in the phenomenon that isolation is layered.
Foundation《Highway engineering pitch and Asphalt Mixture Experiment regulation》(JTJ E20-2011) is to embodiment 2.1 to implementation Vegetable oil regeneration asphalt prepared by example 2.13 carries out the performance tests such as needle penetration, ductility, softening point, viscosity, and test result is such as Shown in table 2.
The performance test results of 2 vegetable oil regeneration asphalt of table
From Table 2, it can be seen that the regenerated vegetable oil regeneration asphalt of plant oil base bitumen regenerant of the present invention, each side Face performance is very close with new pitch, illustrates, recycling aged asphalt regeneration effect is very good.And vegetable oil regeneration asphalt is anti- Fatigability and water stability are significantly larger than new pitch, and the fatigue resistance and water stability for illustrating vegetable oil regeneration asphalt compare new pitch Fortunately, non-aging, service life is long.
On the other hand, during regeneration asphalt, the additive amount of plant oil base bitumen regenerant is considerably less, even less than plants The 10% of object oil regeneration pitch illustrates that plant oil base bitumen regenerant is very high to the regeneration efficiency for recycling aged asphalt, sexual valence Than very high.
