1. What are the uses of bitumen
The main uses of bitumen are waterproofing and corrosion protection. Because bitumen is a high-viscosity liquid with outstanding performance and can be synthesized with different mineral materials, it is widely used for roof waterproofing, ground waterproofing, and anti-corrosion of wood and steel. In addition, there are three types of bitumen: coal char type, petroleum type and natural type. Because of different performance, users need to choose according to the actual situation.
2. The use of bitumen need to pay attention to what
a. Before construction of bitumen, it is necessary to check the condition of the base layer. If the base layer is uneven, it is necessary to level or fill the base layer first, so as to ensure that the bitumen is evenly spread. In addition, before the bitumen construction, the base layer needs to be cleaned. If the conditions are poor, it is recommended to rinse with water to ensure the adhesion of the bitumen.
b. When bitumen construction, a paver can be used, so that the construction effect will be better. When using a paver, it is necessary to preheat the equipment in advance to ensure that the temperature is above 100 degrees Celsius, and to calculate the bitumen and thickness in advance, and adjust the equipment, so as to ensure the uniform thickness of the bitumen layer.
c. Bitumen needs to be heated and constructed at the same time, so after the construction is completed, there needs to be a cooling period for a period of time. Please note that during this period, pedestrians cannot walk on it, let alone vehicles. According to professionals, if the bitumen temperature is lower than 50 degrees Celsius, you can generally walk around, but pay attention to the fact that heavier vehicles cannot walk.
