What Causes Road Surface Collapse?

[SanAurora]

It is caused by the instability of filled roadbeds due to factors such as rainwater erosion, rising groundwater levels soaking the soil, increased vehicle load pressure, or other geological hazards. Preventive measures should include thorough investigation of slope soil properties during the design phase, and calculations to determine whether retaining walls or other protective structures are necessary. When driving on uneven roads, drivers should maintain a relaxed mindset and adopt proper sitting posture. Below are relevant recommendations for driving on uneven roads: 1. Mindset when driving on uneven roads: Drivers should remain patient, avoid agitation, and maintain correct driving posture—keeping the upper body close to the seatback, holding the steering wheel firmly, and minimizing upper body sway or bouncing. 2. Speed control when driving on uneven roads: Reduce speed in advance and traverse at a steady, appropriate pace.
