"Hong Mian card" high viscosity and high elastic asphalt modifier
Product introduction
High viscosity and high elastic asphalt modifier, with polymer as main component, through a certain process synthesis and preparation of modified materials become uniform particle shape, the modified asphalt in the process of rapid and uniform dispersion, significantly improve the strength of asphalt mixture, water stability, low temperature resistance, anti flying fatigue a variety of performance.

Three, product features and methods of use
Solid powder, adding amount of 6~8%, can improve the dynamic viscosity of asphalt 60 degrees Celsius to 100000Pa s above; mainly used for water permeable asphalt pavement.
Use method: the matrix asphalt mixing temperature to 185 degrees Celsius + 5 degrees Celsius, adding a modifier to stir 30~60min, to see the obvious particles to join the asphalt mixture, continue to stir 2~4h, that is, high viscosity and high elastic asphalt.
Four, packaging and storage
Packing: the product adopts double packing, the inner bag is made of polyethylene waterproof plastic bag, the outer bag is composite paper plastic woven bag packaging, net weight 15 kg.
Storage: product available car, train and ship transport, during transport to prevent the sun and rain. Products should be stored in ventilation, cool, dry place, away from the fire. Shelf life of one year.
