沥青路面冷拌补料主要用于维护和修复沥青路面，其功能包括：

Cold mix asphalt pavement patching is mainly used for maintaining and repairing asphalt pavement, and its functions include:

1. **修复裂缝和坑洞**：冷拌补料可以有效填补路面上的裂缝和坑洞，防止进一步恶化，延长路面的使用寿命。

1. * * Repair cracks and potholes * *: Cold mix patching can effectively fill cracks and potholes on the road surface, prevent further deterioration, and extend the service life of the road surface.

2. **降低温度影响**：与热拌沥青相比，冷拌补料在较低温度下施工，适用于气候条件不适合热施工的情况，避免了高温对路面的损害。

2. * * Reduce temperature impact * *: Compared with hot mix asphalt, cold mix asphalt is constructed at lower temperatures and is suitable for situations where climate conditions are not suitable for hot construction, avoiding damage to the road surface caused by high temperatures.

3. **施工便捷**：冷拌补料的施工不需要特殊设备，可以直接手工施工，减少劳动成本和施工时间，便于快速修复。

3. * * Convenient construction * *: The construction of cold mixed materials does not require special equipment and can be directly carried out manually, reducing labor costs and construction time, making it easy to repair quickly.

4. **环保性**：冷拌补料通常采用再生材料，对环境的影响较小，符合可持续发展的要求。

4. * * Environmental friendliness * *: Cold mix additives usually use recycled materials, which have a relatively small impact on the environment and meet the requirements of sustainable development.

5. **粘结效果良好**：冷拌补料配方中的添加剂可以提高与原有路面的粘结力，确保修补的持久性和稳定性。

5. Good bonding effect: The additives in the cold mix supplement formula can improve the bonding strength with the original road surface, ensuring the durability and stability of the repair.

6. **适应性强**：可以用于类型的沥青路面，包括城市道路、乡村公路和停车场等，有较强的适应性。

6. Strong adaptability: It can be used for various types of asphalt pavements, including urban roads, rural roads, and parking lots, with strong adaptability.

通过使用冷拌补料，可以有效维护沥青路面的性能，提升行车舒适度和安全性。

By using cold mix materials, the performance of asphalt pavement can be effectively maintained, and driving comfort and safety can be improved.
