1. Understand the specific conditions of the road to be repaired: consult the engineering drawings and relevant construction instructions to understand the pavement conditions, construction requirements and standards of the road to be repaired.
2. Consult professionals: If you are not sure whether you need to dig the oil removal surface, you can consult relevant professionals, such as road engineers or construction leaders, for more detailed information and suggestions.
3. Considering the actual construction conditions: According to the actual situation, consider whether it is necessary to dig the oil removal surface. For example, if the repaired pavement is in good condition and there are no obvious damages and cracks, then the oil removal surface may not be dug. However, if the road surface is in poor condition and has serious damage or cracks, it may be necessary to dig the degreasing surface for repair.
4. Compliance with relevant regulations and standards: According to relevant national and local regulations and standards, carefully review and evaluate the construction and quality requirements of the repaired roads to ensure that the repaired roads meet the specifications and standards.
Road construction with or without oil removal surface refers to the treatment of roads in the process of road construction. If the oil removal surface needs to be dug, it means that the original pavement asphalt or concrete is roughened or milled, and then paved again; If you don't dig the oil removal surface, directly repair the original pavement or lay a new pavement.
