Routine maintenance of asphalt concrete pavements is crucial for ensuring their service life and driving safety. Specifically, the following measures can be taken:

1. Regular Cleaning: Regularly remove dust, garbage, and other debris from the pavement to prevent these substances from affecting drainage performance or causing wear and tear during vehicle traffic.
2. Crack Inspection: Regularly inspect the pavement for cracks and promptly repair any small, fine cracks. Larger cracks require more specialized repair methods.
3. Disease Prevention: Observe the pavement for ruts, bumps, and other defects. Address any issues promptly to prevent escalation.
4. Maintaining a Good Drainage System: Ensure that drainage facilities are unobstructed to prevent water accumulation and erosion of the asphalt layer. If necessary, add or improve existing drainage systems.
5. Controlling Overloaded Vehicle Traffic: Restrict heavy trucks from traveling on specific road sections to reduce pavement damage caused by excessive weight. 6. Seasonal Maintenance: Implement appropriate protective measures based on the characteristics of different seasons. For example, in winter, strengthen snow removal and anti-skid work; in summer, pay attention to the aging of asphalt materials under high-temperature conditions.
7. Regular Inspection and Assessment: Conduct regular professional inspections and assessments of the road surface condition, and develop reasonable maintenance plans based on the actual situation.
By implementing these methods, the service life of asphalt concrete pavements can be effectively extended, ensuring safe and smooth road traffic.
