Problems solved by technology

When Additive 2, i.e., PPA, was added as such, it resulted in the release of H from bitumen / asphalt treated with Additive 1 2 S, therefore Additive 2 vs Additive 1 H 2 S clearance efficiency has side effects

Embodiment 7、8 and 9

[0122] Therefore, the current experimental results of Examples 7, 8 and 9 (of the second embodiment of the present invention) have confirmed that:

[0123] a) The activators of the present invention surprisingly and unexpectedly significantly reduce the H of Additive 2 to Additive 1 2 Side effects of S clearance efficiency. Therefore, the use of Additive 2 is more beneficial than known from the prior art.

[0124] Therefore, with the development of the present invention, due to the H of additive 2 to additive 1 2 The side effects of S scavenging efficiency have been significantly reduced so that Additive 2| Improve or enhance its various properties.

[0125] The inventors have also observed that the activators of the present invention surprisingly and unexpectedly do not have the same effect on the H of Additive 1 as Additive 2 2 S removal efficiency is adversely affected. In contrast, the activators of the invention surprisingly and unexpectedly increased the H of Additi...
