High Modulus Composite Asphalt Modifiers For Road Pavement Asphalt Road Repair
High Modulus Composite Asphalt Modifiers for Road Pavement
Long life asphalt pavement
1. Description
High Modulus Composite Asphalt Modifiers for Road Pavement is mainly used for the middle layer and the upper layer of asphalt pavement. Small dosage and significant effect, dosage is 0.3-0.4% of the asphalt mixture, and dynamic stability can be raised from 1500 to about 15,000, which can effectively improve anti-rutting performance of the road surface, suitable for bus channels, heavy-duty roads, The intersection and other positions.
Asphalt Modifiers could be customized, modified asphalt also could be customized according to specific performance demand. Specific products could present distinguish performance like noise reduction, aging resistance, fatigue resistance, rutting resistance, reflective cracking resistance. And, our products could cover almost all the mixture types and all the situation where modified asphalt were required.
