Methods and steps:
1. Pavement preparation: Before construction begins, the pavement needs to be prepared. This includes cleaning debris and dust on the pavement and ensuring that the pavement is flat.
2. Base treatment: Before pavement construction, the base needs to be treated. This may include filling potholes and repairing cracks, and ensuring the stability and flatness of the base.
3. Base layer paving: After the base layer is treated, the base layer can be paved. The base layer is generally paved with coarse stone and then compacted. This step is used to strengthen the bearing capacity of the pavement.
4. Middle layer paving: After the base layer is treated, the middle layer can be paved. The middle layer is usually paved with fine stone or asphalt mixture and compacted.
5. Surface paving: After the middle layer is treated, the surface layer can be paved. The surface layer is the layer that is most in contact with vehicles and pedestrians, so high-quality asphalt mixture needs to be selected for paving.
6. Compaction: After paving, compaction work is required. The road surface is compacted by using equipment such as rollers to ensure the stability and flatness of the road surface.

Notes:
1. Check the weather conditions before construction to avoid construction in rainy days or extreme temperatures.
2. Carry out construction according to design requirements and specifications to ensure that the construction quality meets the requirements.
3. Pay attention to the safety of the construction site, set up warning signs, and take necessary safety measures to prevent accidents.
4. Reasonable traffic management is required during the construction process to ensure the safe passage of vehicles and pedestrians.
5. Check the construction quality regularly and carry out necessary repairs and maintenance work to extend the service life of the road surface.
