When used in the natural environment, asphalt will gradually age and its performance will decline due to factors such as light, oxygen, and temperature. Bitumen Emulsifiers can improve its anti-aging performance to a certain extent.
On the one hand, a suitable asphalt emulsifier can form a more stable structure inside the asphalt. It can make the interaction between asphalt molecules more compact and reduce the generation and diffusion of free radicals, which are one of the key factors that cause asphalt aging. By inhibiting their activity, the aging process of asphalt is delayed.
On the other hand, emulsifiers can form a protective film on the surface of asphalt. This film can prevent harmful substances such as oxygen and moisture from directly contacting asphalt, reduce the probability of oxidation and hydrolysis reactions, and thus slow down the aging of asphalt caused by oxidation and hydrolysis.
However, different types and amounts of Bitumen Emulsifiers have different effects. Only by selecting the appropriate emulsifier and using it reasonably can the anti-aging performance of asphalt be better improved, its service life be extended, and the quality and durability of roads and other projects be guaranteed.
