Distinguish between slurry seal and synchronous crushed stone seal in one minute
How to judge whether the road surface after construction is slurry seal or synchronous crushed stone seal? Is it easy to judge?
Answer: It is easy to judge. The road surface with stones fully coated is slurry seal, and the road surface with stones not fully coated is synchronous crushed stone seal. Analysis: Slurry seal is the emulsified asphalt and stones mixed and evenly spread on the road surface, so the asphalt and stones are fully coated. Synchronous crushed stone seal refers to the use of synchronous crushed stone seal equipment to evenly spread clean and dry crushed stones and bonding materials on the road surface through driving rolling to form a single layer of asphalt crushed stone wear layer. Strength is continuously formed under the action of external load. At the same time, due to the surface tension of the fluid asphalt, the asphalt climbs up along the surface of the stone, the climbing height is about 2/3 of the height of the stone, and a half-moon surface is formed on the surface of the stone, so that the area of ??the stone covered by asphalt reaches about 70%!
Are the construction processes the same?
Answer: Different. Continuing from the previous question, from its definition. Slurry seal is a mixing construction process, while synchronous crushed stone seal is a layering construction process!
Similarities: Both slurry seal and synchronous crushed stone seal can be used as waterproof layers on cement concrete. They can both be used for preventive maintenance construction of roads with a grade of: Level 2 and below, and a load of: medium and light.
