What materials are used to repair cement pavement
Cement pavement may be damaged due to various reasons during use, such as cracks, potholes, etc., which need to be repaired in time. So, what materials should be used to repair cement pavement?
First, the type of material.
The materials used to repair cement pavement can be divided into two main categories: inorganic materials and organic materials.
1.Inorganic materials: mainly use cement, sand and other materials, which are mixed to form concrete and repair the pavement. Inorganic materials have the advantages of good durability, high strength and low cost, but they also have disadvantages such as large shrinkage and poor water resistance.
2.Organic materials: Polymer materials such as resin and rubber are mainly used to repair the pavement by mixing them with fillers to form a mixture. Organic materials have the advantages of small shrinkage, good water resistance and good elasticity, but they also have disadvantages such as high cost and poor durability.
2. Select materials.
When choosing a material for repairing cement pavement, the following factors need to be considered:
1.Degree of damage: Different damage levels of pavement require different repair materials and methods. For minor damage such as cracks and peeling, joint filling can be used; For serious damage such as potholes and breakage, it is necessary to use concrete and other materials to repair them.
2.Material properties: Inorganic materials and organic materials have their own advantages and disadvantages, which need to be selected according to the actual situation. If you need to repair quickly and do not require high strength, you can choose organic materials; If long-term durability and high strength requirements are required, inorganic materials can be selected.
3.Environmental conditions: Different environmental conditions can also affect the choice of materials. For example, in a humid environment, it is necessary to choose materials with good water resistance; In cold environments, it is necessary to choose materials with good cold resistance.
4.Cost budget: The cost of different materials is also different, and you need to choose the right material according to your budget. If you have a limited budget, you can choose inorganic materials; If you have a good budget, you can choose organic materials.
Third, the construction method.
The construction method of repairing cement pavement can be divided into the following steps:
1.Surface Cleaning: Clean the surface of the broken pavement to remove debris and loose concrete.
2.Filling material: According to the selected inorganic or organic material, the filler is mixed and stirred evenly and filled into the cleaned pavement. Pay attention to the dense and flat filling.
