Description

Technical Field

[0001] The invention belongs to the technical field of paving materials, and in particular relates to a fiber material for paving. Background Art

[0002] Traditional paving materials primarily rely on loose pavement materials such as sand, gravel, and stone. These materials are widely used in various road construction applications due to their ease of acquisition and low cost. However, with increasing traffic volume and increasingly harsh climate conditions, the limitations of traditional paving materials are becoming increasingly apparent.

[0003] Although loose materials such as sand, gravel and stone have a certain bearing capacity, they have obvious deficiencies in strength, durability and water resistance. Especially in humid environments, these materials easily absorb moisture, causing softening and deformation, which in turn causes problems such as road cracks and potholes.

[0004] These problems not only seriously affect the service life of the road surface, but also pose a huge threat to driving safety. Summary of the Invention

[0005] In order to overcome the above technical problems, the present invention provides a fiber material for paving, which improves the strength and water resistance of the road surface by adding fibers.

[0006] The present invention adopts the following technical solutions: A fiber material for paving, comprising loose pavement material, the paving material further comprising a reinforcing material, a soil solidifying agent and clay, wherein the reinforcing material contains fiber, and the preparation method of the paving material is as follows: S1. Add the reinforcing material to the pavement material and mix it evenly; S2. Spray soil curing agent onto the material obtained by S1; S3. Add clay to the material obtained in S2 and mix them evenly to obtain paving material.

[0007] Preferably, the pavement material is sand or gravel.

[0008] Preferably, the reinforcing material is selected from one or more of polyvinyl alcohol fiber, Tencel fiber, and Lyocell fiber.

[0009] Preferably, the amount of reinforcing material added is 50-1000 g / m2.

[0010] A construction method of fiber material for paving is as follows: Before construction, ensure that the foundation is flat, the slope of the foundation is 3%-5%, and the compaction degree of the foundation is not less than 95%. During construction, the paving materials are evenly spread on the foundation surface, and the paving materials are compacted to complete the construction.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The present invention adds fibers to the paving material. After the fibers are treated with a soil solidifier, the fiber surface can strongly adsorb and fix clay particles, thereby improving the strength and water stability of the clay, thereby improving the strength and water resistance of the road surface as a whole.
