Natural asphalt has a high softening oxidized asphalt temperature, and its modification can significantly improve the heat resistance of asphalt coatings. The softening point of the asphalt itself is very high, generally between 160 and 175 °C, so the very high softening point is followed by the preparation of modified asphalt. The anti-rutting function of the layer.


2. The high nitrogen content in natural asphalt increases the resistance of the asphalt to moisture loss

Natural asphalt and nitrogen elements make natural asphalt a free base with high moisture retention and high resistance by means of functional quality. The existence of other functional group elements and side chains jointly develop the above characteristics. In particular, the improvement of asphalt viscosity, the improvement of oxidation resistance, the adhesion of aggregates and the anti-fall performance are significantly improved. Compared with organic amines, its water damage resistance is more stable and durable.


3. Natural asphalt has excellent anti-aging properties, excellent weather resistance, and the asphalt coating is more durable

Because natural asphalt continuously coexists with the natural environment, its performance is particularly stable, and natural asphalt is very resistant to microbial corrosion, because it may be corroded over millions of years of its composition. It forms the characteristics of a fine and bright protective film, which makes the surface bright and free, and forms a protective layer rich in natural asphalt to avoid damage to the asphalt inside. The high nitrogen content of natural asphalt makes the improved asphalt more viscous and more resistant to oxidation. These qualities will improve the durability of the asphalt pavement, slow its aging, and then extend the life of the journey.


4. Natural asphalt does not contain paraffin, and can enter the high paraffin quality of asphalt

Natural asphalt is not without paraffin in the state of crude oil, but under different conditions in the earth's crust for a long time, the content oxidized asphalt of paraffin is greatly reduced, which is transformed into the existence of other methods. When added to normal asphalt, this property is transferred to the main asphalt to some extent upon recombination, and then reduces its damage in the asphalt.


5. Natural stone asphalt, modified asphalt technology is simple, construction is convenient

Natural stone asphalt is a non-moving particle material, which is stored without agglomerates and is easy to process. Compared with modified asphalt, it generally does not require major modifications to the equipment, which greatly saves construction costs.


6. The performance of asphalt modified by natural asphalt is relatively stable

Compared with artificially modified asphalt such as SBS, natural asphalt is a petroleum-based solid, and its chemical structure is close to that of asphalt. It has very good compatibility with asphalt and can easily coexist with road asphalt. After mixing, the fine molecules that constitute natural asphalt and asphalt not only have the hardness and wear resistance of natural asphalt, but also have the function of resisting asphalt. my country's highway construction requires the use of good materials to help deal with harsh weather and traffic conditions, water damage, and high temperatures.


7. Reduce the temperature sensitivity of asphalt and charge, high-temperature running stability and rutting resistance, running low-temperature strength and crack resistance, running noise reduction function, running durability, extending service life, and reaching the same service life, which can reduce the performance of thin asphalt. thickness


8. Reduce maintenance costs, travel water damage resistance, oil and chemical corrosion resistance, and improve normal working conditions in harsh environments and harsh transportation conditions


9. It can be mixed with other modifiers and polymer modifiers. It can be used for modified asphalt substrates of any hardness. It needs to be self-sufficient. It only needs to adjust different proportions to achieve the purpose of modification. Rock asphalt has better physical properties. Good, easy to store, add simple skills, low carbon and environment.If you have any other questions, please contact us for oxidized asphalt details or contact us directly.
