1. Product Introduction
1) The product is used for producing modified asphalt with wide PG grade, and its SHRP grade can reach PG88-28.
2) Modified asphalt has good storage stability, and can be transported for long distance.
3) Modified asphalt is suitable for dense gradation and gap gradation mixture, and has excellent high temperature track resistance, low temperature crack resistance, anti-water damage and anti-aging performance.
4) Modified asphalt has low high temperature viscosity (175℃ kinematic viscosity Pa·S is ≯1.0), and is easy for mixing, spreading and rolling.
5) Cost of modified asphalt with wide PG grade is lower than that of SBS modified asphalt, and has high performance price ratio.
2. Product usage amount and methods
Add 20-25% of modifier and few quantity of additive into 180±5℃ asphalt, colloid mill isn’t required, and mixed development for 20-40minutes is enough.
