Causes of Road Potholes?

Generally, potholes are caused by substandard foundation treatment, while smaller potholes require analysis of the conditions during pouring. Below is an introduction to the causes of road potholes: 1. Causes: Analyze the conditions during pouring, such as concrete quality, pouring methods, and curing conditions. 2. Solutions: Local damage to cement concrete pavements, if not repaired promptly and effectively, will lead to rapid deterioration. Regular maintenance, including road surface cleaning and joint clearing, is essential. Concrete pavements must be frequently swept to prevent the accumulation of gravel and other hard objects, which can cause cracks or potholes due to repeated wheel pressure. To prevent joint failure, aged or damaged sealants must be replaced in a timely manner.
As a veteran driver with over 20 years of experience, I've seen how most potholes form. It's mainly due to the mischief of water and weather: rainwater seeps into pavement cracks during rain, expands when frozen in winter, widens the cracks, and leaves cavities after thawing—vehicles then compress these into potholes. Heavy trucks accelerate the damage, especially when their wheels repeatedly roll over the same spot, causing faster pavement fatigue. Additionally, aging asphalt or concrete becomes brittle and cracks easily under high temperatures, allowing even light rain to wash out large holes. I remember one night when I couldn’t dodge a pothole in time, hit it, and spent 500 yuan fixing a blown tire. So, stay alert, drive slowly to avoid potholes, and urge municipal authorities to inspect and maintain roads more frequently to reduce such hazards.
Having worked on the road maintenance frontlines for years, the root cause of potholes often lies in weak foundational engineering or poor material selection. Water infiltration is a common culprit—once it seeps into cracks, it erodes the underlying materials, causing loosening. During freeze-thaw cycles, the expansion force of freezing water is immense, enough to tear apart the pavement structure. Heavy vehicle loads, especially frequent truck traffic, accelerate road collapse. Inadequate maintenance is the primary issue; in rainy regions, small cracks rapidly expand into large potholes, and cutting corners during repairs worsens the problem. We often have to patch roads overnight, but tight budgets lead to rushed, short-lived fixes. I recommend adopting high-quality asphalt and improved techniques, designing roads to prevent water pooling from the start—cost-effective and safer.
