Asphalt is often used in construction engineering, but for non-specialized understanding, it may not be understood. For this, Jinan asphalt manufacturer will explain the use of asphalt and precautions for use.
1、 What are the uses of asphalt?
The main use of asphalt is waterproof and anti-corrosion. Because asphalt is a high-viscosity liquid with outstanding performance and can be synthesized with different mineral materials, it is widely used for roof waterproof, ground waterproof and wood and steel anti-corrosion. In addition, there are three types of asphalt: coal coke type, petroleum type and natural type. Because of their different performance, users need to choose according to the actual situation.
2、 What should I pay attention to when using asphalt?
1. Before asphalt construction, it is necessary to check the condition of the base course. If the base course is uneven, it needs to be leveled or patched first to ensure that the asphalt is evenly paved. In addition, before asphalt construction, it is also necessary to clean the base course. If the conditions are bad, it is recommended to wash it with water to ensure the adhesion of asphalt.
2. During asphalt construction, the paver can be used, so the construction effect will be better. When using the paver, it is necessary to preheat the equipment in advance to ensure that the temperature is above 100 ℃, and calculate the asphalt and thickness in advance, and adjust the equipment, so as to ensure the uniform thickness of the asphalt layer.
3. The asphalt needs to be heated while construction, so after construction, there needs to be a cooling period for a period of time. During this period, pedestrians should not walk on it, let alone vehicles. According to a special person, if the asphalt temperature is lower than 50 ℃, you can generally walk, but pay attention to the fact that heavy vehicles cannot walk.
Because asphalt is used in different situations, its construction methods and techniques are different. For inexperienced users, they need to know the situation before construction. If you want to know more about asphalt, please pay attention to our website http://www.ycgjglcl.com 。
