Modified asphalt: index characteristics, uses and market analysis.
1. Definition and classification of modified asphalt.
Modified asphalt refers to asphalt materials that change the physical and chemical properties of asphalt through specific processing methods to improve its performance in use. Modified bitumen is generally divided into the following categories:
1) Oxidized asphalt: Through oxidation treatment, the molecular structure of asphalt is changed to improve its hardness and stability.
2) Polymer modified asphalt: Polymer is added to asphalt to improve the elasticity and weather resistance of asphalt through polymerization.
3) Heat-treated asphalt: through heating, mixing, filtration and other processes, the composition and structure of asphalt are changed to improve its high-temperature stability and durability.
2. Main index characteristics.
The main index characteristics of modified asphalt include setting time, high temperature stability, low temperature crack resistance, weather resistance, etc. Specific indicators vary depending on the modified asphalt method and the field of application.
1) Setting time: The setting time of modified asphalt is usually longer, which is conducive to the fluidity in the construction process.
2) High temperature stability: The modified asphalt has good high temperature stability and can withstand long-term use in a high temperature environment.
3) Low temperature crack resistance: The modified asphalt has strong low temperature crack resistance and can resist cracking in low temperature environment.
4) Weather resistance: The modified asphalt has good weather resistance and can resist the erosion of ultraviolet rays, oxidation and other factors.
3. Use. Modified asphalt is widely used in construction, transportation, fuel and other fields. In the construction field, modified asphalt can be used to make waterproof materials, anti-corrosion materials, etc.;In the field of transportation, modified asphalt can be used to pave road surfaces, make waterproof layers, etc.;In the field of fuels, modified bitumen can be used to make biofuels, among other things.
