The compaction temperature of material reduces by 20~30 DEG C.
But, the research of current multifunctional and composite type bituminous paving additive also in the starting stage, each product it is specific
Using effect is still among practice, especially with warm mix effect and composite type pitch road surface additive with low cost also very
Rareness, the defect existed in view of above-mentioned existing composite type pitch road surface additive, the present inventor is based on being engaged in such product
Practical experience and professional knowledge that design studies are enriched for many years, and coordinate the utilization of scientific principle, actively it is subject to research and innovation, it is intended to carry
Go out a kind of new warm mix type water resistant and damage asphalt road surface reinforcing material, for energy-saving and emission-reduction, prolonging service life of pavement, support personnel
Life security, there is important practical significance.
