As an important road material modifier, asphalt high viscosity agent has shown significant advantages in improving the durability and rutting resistance of asphalt pavement in recent years. By using asphalt high viscosity agent scientifically and rationally, it can not only effectively improve the physical and chemical properties of asphalt pavement, but also significantly improve its service life and driving safety.
The main function of asphalt high viscosity agent is to enhance the adhesion and cohesion of asphalt. During the use of traditional asphalt pavement, the adhesion between asphalt and aggregate often decreases due to factors such as repeated rolling of vehicles, temperature changes and water erosion, and then peeling, cracking and other problems occur. Asphalt high viscosity agent, through its special chemical structure and composition, can significantly improve the adhesion between asphalt and aggregate, making the asphalt mixture more compact and firm, thereby effectively resisting the damage of the external environment.
In terms of improving the rutting resistance, asphalt high viscosity agent also plays an important role. Rutting is a common form of disease in asphalt pavement, mainly due to the plastic deformation of pavement materials caused by the long-term action of wheel load. Asphalt high viscosity agent increases the viscosity of asphalt and improves the shear resistance of asphalt mixture, so that it can better maintain shape stability when facing wheel load and reduce the generation of rutting.
In addition, asphalt high viscosity agent can also improve the anti-aging performance of asphalt pavement to a certain extent. Asphalt materials are exposed to the natural environment for a long time, they are easily affected by ultraviolet rays, oxygen, moisture and other factors, which will cause aging and performance degradation. Some components in asphalt high viscosity agent can absorb or shield these harmful factors, thereby delaying the aging process of asphalt and maintaining its good physical and chemical properties.
It is worth mentioning that the use of asphalt high viscosity agent can also reduce the noise pollution of asphalt pavement. Because the viscosity enhancer improves the bonding force between asphalt and aggregate, the road surface is smoother and tighter, the noise generated by vehicle driving is reduced, and a more peaceful living environment is provided for urban residents.
In summary, asphalt high viscosity agent has significant advantages in improving the durability and anti-rutting performance of asphalt pavement. By using asphalt high viscosity agent scientifically and rationally, not only can the service life of asphalt pavement be extended, but also driving safety and the quality of life of residents can be improved. Therefore, in future road construction, the application prospects of asphalt high viscosity agent will be very broad.
