Answer: Potholes in asphalt paving are primarily caused by the combination of water infiltration, temperature fluctuations, and traffic stress. Water seeps into cracks in the asphalt, weakening the base layer beneath. When temperatures drop, the water freezes and expands, causing the asphalt to shift and crack further. As vehicles drive over these weakened areas, the pressure causes the asphalt to break apart, forming a pothole. Over time, repeated freeze-thaw cycles, poor drainage, and lack of maintenance accelerate pothole formation.

Answer: Potholes in asphalt paving are primarily caused by the expansion and contraction of water that has seeped into the pavement. This process, combined with the wear and tear from traffic, weakens the asphalt surface and eventually leads to the formation of potholes. Here's a detailed breakdown: 1. Water infiltration: Cracks or small openings on the asphalt surface allow water to seep into the pavement. This can be due to poor drainage, heavy rainfall, or melting snow and ice. 2. Freeze-thaw cycles: In colder climates, water that has entered the pavement can freeze during winter months. When water freezes, it expands and forces the asphalt to crack and weaken. As temperatures rise and the ice melts, the water seeps deeper into the pavement, causing further damage. 3. Wear and tear: As vehicles pass over the weakened sections of the asphalt, the pavement becomes further stressed, leading to cracking, deformation, and the eventual formation of potholes. This process is accelerated under heavy traffic, particularly with large commercial vehicles. 4. Inadequate maintenance: Neglecting regular maintenance of asphalt surfaces, such as sealcoating and prompt repair of cracks, can contribute to the development of potholes over time. 5. Poor construction: Improper installation or use of low-quality materials can result in a weaker pavement structure that is more susceptible to pothole formation.
