1. Product Introduction
The product is used for producing rubber and plastic alloy modified asphalt of wide PG grade, its SHRP
grade can reach PG88-28.
2. Product Advantages
1) The produced asphalt modified with rubber and plastic alloy asphalt modifier has good storage stability so as to be transported for a long distance.
2) The modified asphalt is applicable to dense-graded, gap-graded mixture, and has excellent resistance
to high-temperature rut, low-temperature crack, water damage, aging.
3) The modified asphalt has lower high-temperature viscosity(175℃ kinematic viscosity Pa·S≯1.0),
easy to mix, spread, roll.
4) Wide PG rubber and plastic alloy modified asphalt has lower cost than SBS modified asphalt, and it is
3. Product usage amount and methods
Add 20～25％ modifier and a small amount of other additives to 180±5℃ asphalt using SBS modified
asphalt equipment, shear and grind with colloid mill, and then mix and develop.
