What causes potholes in asphalt paving?

Answer: Potholes form when water seeps into cracks in the asphalt, freezes, and expands. This weakens the pavement, and traffic pressure breaks it apart, creating a hole.

Answer: Potholes in asphalt paving are primarily caused by the combination of water infiltration, freeze-thaw cycles, and the stress of traffic. Here’s how the process works: - Water seeps into cracks in the asphalt and reaches the underlying layers[1][2][5]. - When temperatures drop, the trapped water freezes and expands, pushing the pavement upward[1][3][5]. - As temperatures rise, the ice melts, leaving a gap beneath the surface[1][3][5]. - The weight of vehicles passing over these weakened spots causes the pavement to break and collapse, forming a pothole[1][2][3][5]. Poor drainage, aging asphalt, heavy traffic, and temperature fluctuations all accelerate this process[2][6][8].

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: Various Causes : 1. Poor material 2. oil leaks 3. segregation 4. poor sub grade 5. grade issues 6. ponding water

Answer: When ur asphalt gets all cracked up and water or weeds starts to get in it

Answer: Alot things can cause it

Answer: From water freezing and contracting while units drive over it.

Answer: Either from untreated cracking in surface or from failed subgrade

Answer: Weak soil under the asphalt causes potholes..

Answer: Heavy traffic, un-maintenance driveway/parking lot

Answer: water getting into the base poor base or subsoils such as clay poor paving job or too thin or poor compaction

Answer: The base has been compromised or was not properly stabilized

Answer: Poor job from the start The age of the asphalt water and freeze damage

Answer: Water damages the base

Answer: Generally speaking potholes are caused by excessive cracks and water deteriorating the sub base.

Answer: Cracks crack filler if nothe put in right and cleaned really good be u put in

Answer: A pothole is a structural failure in an asphalt pavement, caused by the presence of water in the underlying soil structure and the presence of traffic passing over the affected area. Introduction of water to the underlying soil structure first weakens the supporting soil

Answer: Water. Oil spots

Answer: Oil,water.etc

Answer: Oil gas. Spills. Oxidation ravell. Pavment. Drys. Out. Gets. Loose. And. Then. Holes. Appear

Answer: Base fail
