Background Introduction
The asphalt mixture mixed with high modulus agent is suitable for high-grade highway asphalt pavement engineering with large traffic volume and heavy-duty vehicles, taking into account high carrying capacity, anti-fatigue performance, anti-high temperature permanent deformation and anti-water damage performance, in line with the performance requirements of long-life asphalt pavement, its technology has been successfully applied at home and abroad.
The modulus is the ratio of stress to strain, under certain stress conditions, the modulus increases the strain decreases, the reaction to the pavement structure is the modulus increases the pavement deformation decreases, so the asphalt mixture mixed with high modulus agent can also play a role in anti-rutting.
Asphalt admixture
-- High modulus agent
After years of technology and research and development, Zengguang Technology has developed a special high modulus asphalt mixture additive for airports.
Product introduction:
High modulus agent is a new type of light gray or light black granular pavement composite material, which is mixed with matrix asphalt according to a certain ratio and made of high temperature stable asphalt by special process. It is suitable for heavy traffic, high temperature area, long longitudinal slope and airport pavement, which not only greatly improves the dynamic modulus and high temperature stability of asphalt mixture, what is more important is to solve the problem of rutting and other deformation pavement problems caused by insufficient pavement strength and poor high temperature performance of asphalt mixture.
High modulus agent is an admixture that can significantly improve the stiffness modulus and fatigue resistance of asphalt mixtures. The asphalt concrete added with high modulus agent is called high modulus asphalt concrete. High modulus asphalt concrete achieves the purpose of improving stiffness modulus and fatigue resistance through the characteristics of hard binder, high binder dosage and low porosity.
By improving the modulus parameters of asphalt mixture, the thickness of asphalt layer structure can be thinner under the same cumulative axis, and the bearing capacity and service life can still meet the design requirements or even higher. The main purpose of high modulus agent is to improve the modulus parameters in structural calculation, reduce the thickness of asphalt layer, meet the requirements of structural calculation and reduce the project cost, that is, to save a lot of stone, it is of great significance for areas where there is a shortage of high-quality stone.
Product packaging
Technical features:
1, greatly improve the viscosity of asphalt, improve the dynamic modulus of asphalt mixture;
2, can save a lot of stone, for the shortage of high-quality stone areas to reduce unnecessary expenses;
3, in the cumulative same axis under the action of the asphalt layer structure thickness can be thinner, bearing capacity and service life can still meet the design requirements, or even higher;
4. It has the function of caulking, reinforcement, cementation, fine aggregate frame and deformation recovery on asphalt pavement;
5, significantly enhance the high temperature rutting resistance, improve the low temperature water stability of concrete, low temperature cracking resistance;
6, the construction process is simple, cost-effective. Asphalt concrete can be modified directly without special equipment.
7, greatly improve the high temperature stability of asphalt mixture, significantly improve the low temperature deformation and anti fatigue performance, dynamic stability can reach more than 5 times of the original asphalt concrete.
Construction process:
The application process of high modulus agent is simple, the high modulus agent is directly put into the aggregate mixing tank for dry mixing, and the dry mixing time of the regular asphalt mixture shall be extended by 10-15S. Then add asphalt and mix it for the same time as normal. Through the mixing process, the high modulus agent is softened and dispersed, and can be melted with asphalt into a uniform state, which can achieve the effect of modified asphalt concrete.
It is necessary to appropriately increase the material temperature. In general, for mixtures with high modulus agents, the aggregate heating temperature is 190-200 ℃, the asphalt temperature is 160-170 ℃, and the temperature of the mixed mixture is 170-185 ℃.
Executive standard:
The asphalt mixture mixed with high modulus agent shall not only meet the technical requirements of the Technical Specification for Construction of Highway Asphalt Pavement (JTG F40-2004), but also meet the requirements of the Modified Additives for Asphalt Mixtures Part 8: High Modulus Agent (JT/T 860.8-2023).
