Modified asphalt is to add external admixtures (modifiers) such as rubber, resin, high molecular polymers, finely ground rubber powder or other fillers, or take measures such as mild oxidation processing of the asphalt to make the asphalt or asphalt mixture The performance of the asphalt binder can be improved.

Many users who use emulsified asphalt do not understand why emulsified asphalt needs to be demulsified, nor what its use is. Therefore, the editor of emulsified asphalt manufacturer Sinoroader would like to take this opportunity to explain in detail the relevant knowledge of emulsified asphalt demulsification.

As we all know, micro-surfacing and slurry sealing are both relatively common preventive maintenance techniques, and the manual methods are also similar, so many people don’t know how to distinguish them in actual use, so the editor of Sinoroader would like to take this opportunity Let me tell you the difference between the two.

Asphalt is a highly viscous organic liquid with a black surface and is soluble in carbon disulfide (a golden-yellow, foul-smelling liquid). They often exist in the form of asphalt or tar.
Asphalt can be mainly divided into three types: coal tar pitch, petroleum asphalt and natural asphalt: among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural asphalt is stored underground, and some form mineral deposits or accumulate on the surface of the earth's crust.

Asphalt mixer safety standards
1. Small asphalt mixer
It should be installed in a flat position, and square wood should be used to cushion the front and rear axles so that the tires are elevated to avoid movement when starting. ?
2. Small asphalt mixers should be subject to secondary leakage protection. After the power is turned on before going to work, they must be carefully inspected. After an empty test run, they are found to be qualified before they can be used. During trial operation, it should be checked whether the mixing drum speed is appropriate. Under normal circumstances, the speed of the empty truck is slightly faster than that of the heavy truck (after loading) by 2 to 3 revolutions. If the difference is large, the ratio of the moving wheel and the transmission wheel should be adjusted. ?

Asphalt concrete is a mixture made by manually selecting mineral materials with a certain gradation composition and a certain proportion of road asphalt materials, and mixing them under strictly controlled conditions.
Question: Some people put asphalt mixing equipment into road machinery. Is asphalt concrete concrete?
