Low temperatures in winter will affect the effect of asphalt spreading. When constructing Asphalt Distributor Truck, special attention should be paid to the following points:
1. Asphalt heating control
- Heat the asphalt to 160-180℃ before construction to ensure fluidity
- Use insulated tank trucks for transportation to avoid rapid temperature drop during transportation
2. Equipment preheating preparation
- Start the equipment heating system in advance to preheat the pipes and nozzles
- Check whether the heat transfer oil circulation is normal to prevent condensation and blockage
3. Construction time selection
- Try to work during the high temperature period of the day (10:00-15:00)
- Construction should be suspended when the ambient temperature is below 5℃
4. Spraying operation adjustment
- Appropriately reduce the spraying height to reduce heat loss
- Immediately cover with gravel after spraying to help keep warm
5. Maintenance points for Asphalt Distributor Truck
- Empty the residual asphalt in the pipeline after construction every day
- Focus on cleaning the nozzle to prevent blockage after cooling
6. Emergency preparation
- Prepare enough diesel blowtorches for local heating of solidified parts
- Prepare insulation materials to cover key parts of equipment
Check weather forecast before construction to avoid rainy and snowy weather. It is recommended to use low-temperature modified asphalt to improve winter adaptability.
