高速公路沥青路面预防性养护时机与技术方案优化分析

Key Points

• This research aims to optimize the timing and technical strategies for preventive maintenance of asphalt pavements to enhance longevity and efficiency.
• Analyzed the performance degradation mechanisms and typical failure characteristics of asphalt pavements.
• Compared various preventive maintenance techniques such as fog seal, micro-surfacing, and thin overlay based on their conditions and performance features.
• Developed a multi-criteria evaluation model integrated with life cycle cost analysis (LCCA) for optimizing maintenance strategies.
• Identifying optimal maintenance timing and matching the right technique maximizes preventive maintenance benefits.
• Data-driven dynamic optimization strategies improve the efficiency and intelligence of asphalt pavement maintenance management.
