The viscosity and temperature characteristics of modified asphalt are of great significance to environmental and safety issues, mainly reflected in the following aspects:

1. Too high mixing and compaction temperature will cause aging of modified asphalt: According to the research results in the reference information, too high mixing and compaction temperature will cause aging of modified asphalt. The aging of modified asphalt will reduce its performance and service life, which will affect the safety of road use.

2. Too high mixing and compaction temperature will cause environmental problems: too high mixing and compaction temperature of modified asphalt will lead to volatilization and combustion of asphalt, release harmful gases and particles, and pollute the environment. These harmful substances have adverse effects on air quality and ecological environment.

3. The determination of reasonable mixing and compaction temperatures is crucial to production safety: according to the research results in the reference information, when testing the viscosity of modified asphalt, it is necessary to specify the corresponding shear rate at the test temperature. Reasonable determination of mixing and compaction temperature of modified asphalt can avoid aging and environmental problems caused by excessive temperature, so as to ensure the safety of production process.

To sum up, the viscosity and temperature characteristics of modified asphalt are of great significance to the environment and safety issues, and reasonable determination of mixing and compaction temperatures can avoid the aging of modified asphalt, environmental pollution and production safety problems.
