The difference between medium temperature asphalt and modified asphalt
Medium-temperature asphalt is a common asphalt material whose properties and uses are similar to petroleum asphalt. However, modified asphalt is a type of asphalt that has been processed and has a higher softening point and better weather resistance, so it has better performance in some specific applications.
First of all, medium-temperature asphalt and modified asphalt differ in processing methods. Medium-temperature bitumen is obtained by distilling petroleum, while modified bitumen is obtained by processing petroleum by oxidation, pyrolysis or catalysis. These processing methods can change the composition of the asphalt and thus improve its properties.
Secondly, there are also differences in physical properties between medium-temperature asphalt and modified asphalt. Modified asphalt has a higher softening point, which means it retains some flexibility and ductility at high temperatures. In addition, modified asphalt is also more weather-resistant because it is less susceptible to ultraviolet rays and other environmental factors.
Finally, medium-temperature asphalt and modified asphalt also differ in their uses. Medium-temperature asphalt is mainly used in road construction, waterproofing materials, etc., while modified asphalt is more used in the manufacture of structural materials such as buildings and bridges.
In conclusion, there are differences between medium-temperature asphalt and modified asphalt in terms of processing methods, physical properties and uses. Therefore, when choosing to use, it is necessary to choose according to the specific application scenarios and requirements.
