From the data in table 1, it can be seen that bituminous cement provided by the invention have excellent adhesion strength, can reach 2.5MPa and
More than, this is because carbolineum can promote the infiltration of adhesive each component, adhesive is enable to penetrate into Bituminous concrete surface or road surface base
The inside configuration of matter pitch, and then enhance the adhesive property of bituminous cement.
By above-described embodiment it is found that bituminous cement provided by the invention has higher adhesive property and permeance property,
It can penetrate into inside pitch, improve new, Bituminous concrete surface adhesive layer intensity.
In addition, bituminous cement purity provided by the invention is higher, influence of the impurity to adhesive property is avoided；Asphalt binder
Agent stability is preferable, and adhesion strength amplitude of variation is small, can further extend the service life of bituminous cement, the short time is avoided to deposit
Storage stability decline cause adhesive can not use result in waste of resources；Bituminous cement under cryogenic flawless, constantly
Ripper has excellent flexibility, and under the high temperature conditions, no trickling, sliding and drip phenomenon illustrate asphalt binder provided by the invention
Agent has excellent crack resistance at low-temperature, has expanded the application range of bituminous cement；Bituminous cement provided by the invention is also
It can be made to be used as sticking layer oil or priming oil by runoff investigation；Finally, bituminous cement provided by the invention has preferable
Water resistant evil performance and antifatigue cracking performance, there is preferable market value.
Although above-described embodiment is made that detailed description to the present invention, it is only a part of the embodiment of the present invention,
Rather than whole embodiments, people can also obtain other embodiment according to the present embodiment under the premise of without creativeness, these
Embodiment belongs to the scope of the present invention.
