Asphalt is a combination of heat, pressure, sodium asphalt sulfonate oxidation, catalyst, bacteria, etc. It is generally used to modify the base asphalt. The physical properties of bitumen are close to "coal".


distribute

The natural stone and asphalt minerals found in my country are mainly distributed around Xinjiang, Qinghai and Qingchuan in my country.


Qingchuan bituminous deposits are scattered in the Longmenshan area in northern Sichuan Province, which enjoys a national reputation. Preliminary proven reserves exceed 3 million tons. Estimated reserves are 10 million tons. It is estimated to have reached 1 billion tons so far.


Sichuan Jiangbei natural asphalt is composed of asphalt with a molecular weight of up to 10,000, and is composed of 0.87% of metals such as carbon 81.7%, hydrogen 7.5%, oxygen 2.3%, nitrogen 1.95%, sulfur 4.4%, aluminum 1.1%, silicon 0.18%. Among them, the content of carbon, hydrogen, oxygen, nitrogen and sulfur is relatively high, and the macromolecules of each asphalt almost all contain the above elements in the polar function, making it extremely strong in the adsorption force on the rock surface.


use

The active deformation of asphalt coating is a common phenomenon of asphalt coating cracking in the world. According to statistics, about 80% of traffic accidents are caused by the deformation of traffic composition. Through engineering practice, it is found that modified asphalt plus asphalt has great advantages under high sodium asphalt sulfonate temperature stability, and can successfully deal with high asphalt pavement problems related to rails due to heavy traffic and overload, early diseases and other phenomena.


feature


1. On the rut

Travel experiments and practice have proved that asphalt modifiers can effectively improve the anti-rutting function of asphalt pavement, delay the formation of pavement ruts, reduce the depth of rutting and the appearance of fatigue shear cracks.


2. fall resistance

In Qingchuan asphalt, nitrogen exists in the form of functional quality, which makes the asphalt have high wettability and high resistance to free oxidation radicals, especially because the adhesion to aggregate and anti-corrosion strength are significantly improved.


3. Aging and high temperature resistance

The softening temperature of natural asphalt itself reaches more than 300 ℃, and it participates in the base asphalt, which has excellent high temperature resistance and anti-aging properties.


4. Patience

Durability: Under asphalt, for example, should be used in the field to experience combined damage from light, rain, rain, bacteria, etc., its durability.


Asphalt has a strong effect on microbial corrosion and has the characteristics of forming a fine photoprotective film on the leisure surface. The participation of asphalt rock greatly improves the overall UV resistance of the asphalt, improves the durability of the asphalt pavement, delays the aging of the asphalt, and thus prolongs the service life of the road.If you have any other questions, please contact us for sodium asphalt sulfonate details or contact us directly.
