How to improve road repair efficiency through fast, low-carbon, and durable maintenance methods,under Extreme Climate Conditions
Historically, traditional pavement M&R approaches have struggled to balance operational efficiency with long-term performance. Conventional pothole fixing using cold-mix asphalt mixture is a fast process, but yields poor durability and subpar surface smoothness. Conversely, preventive maintenance techniques like hot-mix patching and slurry seals offer good durability, but they are costlier, more labor-intensive, and require longer construction times. Because pavement M&R routine is a continuous necessity, these inefficiencies contribute heavily to cumulative carbon emissions, making the reduction of CO2 a critical priority under concerns of climate change.
Research Background
1. Climate Change and Carbon Emission Challenges
- Pavement maintenance is a continuous and high-frequency activity, contributing significantly to cumulative carbon emissions.
- Reducing CO₂ emissions has become a critical issue under global climate change.
2.Increasing Pavement Deterioration and Potholes
- Conventional maintenance and rehabilitation methods are ineffective in preventing recurrence.
- Pothole occurrence continues to increase in THB highways.
3. Maintenance and Rehabilitation (M&R)
- Conventional M&R: FAST, but poor in quality and durability.
- Preventive maintenance: DURABLE, but costly and less efficient.
4. Sustainability and Resource Constraints
- With increasing pothole occurrences and limited resources, a low-carbon technique to fix potholes has become a key challenge.
