High Temperature Additive Asphalt Black Top Road Repair Construction And Maintenance
High Temperature Stability Asphalt Pavement Anti-rutting Additive Asphalt Additives Agent
Long life asphalt pavement
1. Description
High Temperature Stability Asphalt Pavement Anti-rutting Additive Asphalt Additives Agent is composed of polymer composite. It is especially developed to resist the rutting of hot mix asphalt wearing course. It has the advantages of high temperature stability, fatigue resistance performance, water stability and the low temperature crack resistance. It can be applied to various of asphalt mixture and greatly improve the performance of asphalt mixture.

3. Advantages
A. Aggregate viscosity-increasing effect: the anti-rutting asphalt additives is first dry mixed with the aggregate, and partly melted on the surface of the aggregate to form a film, which improves the adhesion of the aggregate, which is equivalent to pre-modifying the aggregate.
B. Modified asphalt effect: during the wet mixing and transportation process, the anti-rutting asphalt additives is partially dissolved or swelled in the asphalt to form a cementation effect, so as to achieve asphalt modification effects such as increasing the softening point temperature, increasing the viscosity, and reducing the heat sensitivity, so as to make the asphalt mixture Improved pavement resistance to penetration and water damage.
C.Fiber reinforcement: the microcrystalline area formed by the polymer has considerable stiffness, which is partially drawn into plastic fibers during the mixing process, and bridges and crosslinks in the aggregate skeleton to form fiber reinforcement.
D.Deformation recovery effect: the elastic component of the anti-rutting asphalt additives has the function of elastically recovering the deformed part of the pavement at higher temperatures, thus reducing the deformation of the formed asphalt pavement.
4. Application Scope
High Temperature Stability Asphalt Pavement Anti-rutting Additive Asphalt Additives Agent is mainly used in the middle, upper and lower layers of asphalt pavement construction and maintenance engineering for all types of surface and base layers.
* Heavy-duty channelized traffic roads, long and steep roads, and roads in mountainous and heavy hilly areas with more sharp bends, which are more severely damaged by rutting.
* Sections with heavy traffic and heavy load.
* Important road sections such as highways, crossroads, airport runways, and municipal arterial roads.
