1、 Modified wax used as a warm mix agent for road asphalt:
At present, green road construction is receiving increasing attention, and reducing construction temperature, energy consumption, and pollutant emissions have become the main goals pursued
The addition of warm mixing agents can effectively improve such related problems. There are many types of warm mixing agents, and modified wax is one of them.
Modified wax is a viscosity reducing warm mixing agent, which mainly has the following characteristics:
1. Improve the high-temperature temperature performance of asphalt and improve its thermal sensitivity.
2. Effectively reduce the mixing and construction temperature of asphalt mixtures.
3. Improve the low-temperature viscosity of asphalt and enhance the rheological resistance of asphalt pavement.
4. Effectively reduce the high-temperature viscosity of asphalt.
5. Reduce harmful gas emissions.
Dongguan Yangting New Material Technology Co., Ltd. is a high-quality wax additive manufacturer in China, specializing in the production of various wax additives. The products have been successfully applied in ten industries
Several industries, tens of thousands of customers.
2、 Significantly improve the anti rutting performance of asphalt mixtures:
Ruts are continuous longitudinal grooves formed on asphalt pavement during high temperature seasons due to repeated rolling of vehicles in the same direction and concentrated passing of wheels
Slot deformation, with a depth generally ranging from a few millimeters to several centimeters, and even permanent vertical deformation under repeated automotive loads, especially in
In the hot season, this situation is more likely to occur, and it has become the most serious and common damage to asphalt pavement.
Oxidized polyethylene wax has excellent cold resistance, heat resistance, and wear resistance, as well as good chemical stability and good compatibility with asphalt. It is used as asphalt
The modifier can quickly bind with asphalt, improve the composition of asphalt, and there is no need to worry about precipitation from asphalt when the state changes. It can be mixed and stirred in asphalt
Rapid and uniform melting and dispersion during the process improve the viscosity of asphalt, enhance its ability to resist flow, and significantly enhance the rutting resistance of asphalt mixtures
Can, while meeting other performance requirements of asphalt mixtures.
Compared with the original asphalt, asphalt modified with oxidized polyethylene wax exhibits high temperature performance, elongation, stretching, elasticity, and compatibility with the mixture
In terms of performance, anti-aging performance and so on, it has obvious improvement and enhancement; It can effectively improve the storage stability of modified asphalt, reduce the occurrence of segregation, and at the same time
Greatly increasing the low-temperature ductility of modified asphalt, improving high-temperature resistance to rutting and low-temperature resistance to brittle cracking, suitable for use in high-temperature and low-temperature areas.
Experimental data shows that as the content of oxidized polyethylene wax modifier increases from 0% to 20%, the softening point of asphalt increases, the penetration rate decreases, and the
The increase in temperature ductility leads to better scalability, improved elasticity recovery, and a significant improvement in high and low temperature performance. Therefore, as a drain
The oxidized polyethylene wax with green modifier has a large amount of usage and good market prospects.
