A pothole is a depression in a roadway that can range from a few inches wide and a few inches deep, to several feet wide and sometimes a foot deep. Potholes jar the tires of cars driving over them sometimes causing handling and suspension problems.
Since potholes form in both gravel and paved roads it is not a simple matter of rain washing the material away, and since rain falls equally on all the road the wearing effect should be equal over the whole surface. Another consideration is that potholes seem to appear in the spring. Furthermore, potholes can form in cold climates as well as hot climates only for different reasons. Potholes seem to be the result of several factors depending on where you live.
In colder climates:
- The freezing and thawing of the road surface lifts the road material up making cracks in the surface.
- These cracks formed to fill with water which freezes and expands the cracks wider.
- The thawing water washes the broken material out of the cracks
- Cars traveling the road hit the small cracks vibrating even more material loose from the area.
- As the holes continue to grow the bumping gets more severe, breaking more of the surface loose.
- As these breaks get wider the asphalt is able to rock loose leaving the pothole behind.
In warmer climates:
- Over time as the sun heats up the asphalt it will start to dry out the oil and binders which hold the asphalt in place.
- Once the asphalt reaches a critical point of dryness it becomes less able to absorb shock from the cars traveling on the road or parking lot.
- Eventually the asphalt will form fine cracks, typically found in the drive path areas of roads and parking lots.
- When winter rains come these cracks fill with water and begin to widen.
- Once the cracks are large enough the asphalt will pop out do to vibrations from vehicular traffic.
In either climate the pothole process is initiated by small breaks in the surface. Some are caused by freeze/thaw cycles and others are caused by asphalt drying out due to long term sun exposure. The potholes continue to form from exposure to rain and traffic. After time the original material becomes loosened and eventually fails completely. Leaving behind the pothole.
The next question is why do potholes appear in the same places year after year. This results from the repair of potholes with cold pack asphalt. If the material is not installed properly (bonded in palace with tar and tamped and rolled into place) it is easier to break up than the rest of the road surface, Sort of like the problems with a poorly filled dental cavity. As a result the new pothole forms where the surface is weakest, the site of the poor repair.
On gravel roads potholes often result from another cause, the natural frequency of the tire and shock absorber system of car. These potholes can be either individual depressions or ridges that run normal to the flow of traffic. This latter condition is more commonly known as a washboard road. In this case some minor irregularity of the road causes a car tire to bump up. When it comes down it impacts the clay and gravel compacting it slightly. This forms a depression which causes another compression and release of the suspension. The period of the movement is due to the natural frequency of the system. Eventually this causes a series of depressions each time the tires rise and fall.
On the lighter side:
It is caused by marijuana smokers throwing their roaches out the windows. That causes pot holes.
What else can I help you with?
What kind of weathering creates potholes?
Freeze-thaw weathering is a common process that creates potholes. Water seeps into cracks in the road, freezes during cold weather, expands, and weakens the pavement material. This cycle of freezing and thawing causes the road surface to break up, leading to the formation of potholes.
Why are roads covered in cracks and potholes in the winter time?
Roads can develop cracks and potholes in winter due to the cycle of freezing and thawing. When water seeps into cracks in the road surface and freezes, it expands, causing the pavement to crack. As vehicles drive over these weakened areas, the pavement can break apart, forming potholes. Additionally, the use of road salt and other de-icing chemicals can further deteriorate the road surface.
Does ice wedging often causes potholes in streets?
Ice wedging is not a common cause of potholes in streets. Potholes are typically formed due to a combination of factors such as weathering, traffic, and poor road maintenance. Ice wedging primarily occurs in natural environments where water freezes and expands in cracks in rocks or soil.
How are potholes formed in roads?
Potholes are caused by vibration from traffic, and also by movement of the ground under the road. In cold weather, the water in the ground freezes and thaws - this makes the ground expand and contract, and makes cracks in the road. Traffic running over the cracks breaks them open further and creates a pothole.
How does ice wedging relates to potholes?
Ice wedging is a process where water seeps into cracks in rocks or pavement, freezes, and expands, causing the cracks to widen and break apart. This can contribute to the formation of potholes on roads, as repeated freezing and thawing cycles weaken the pavement, leading to the development of potholes over time.
Can abrasion cause potholes in the road?
No, potholes are typically caused by a combination of factors such as water seepage, freezing and thawing cycles, and heavy traffic. While abrasion from vehicle tires can contribute to the deterioration of road surfaces, it is not the primary cause of potholes.
What kind of weathering creates potholes?
Freeze-thaw weathering is a common process that creates potholes. Water seeps into cracks in the road, freezes during cold weather, expands, and weakens the pavement material. This cycle of freezing and thawing causes the road surface to break up, leading to the formation of potholes.
What are potholes made of?
Potholes are typically made of a combination of asphalt, gravel, and other materials used in road construction. These materials weaken over time due to factors like water infiltration, freeze-thaw cycles, and heavy traffic, causing the road surface to deteriorate and form potholes. Regular maintenance and repairs help prevent potholes from forming.
Does comprehensive insurance cover damages caused by potholes on the road?
It may and My policy does
Why are roads covered in cracks and potholes in the winter time?

What causes potholes to form in streets and roadway?
They are called potholes because a pot (cookware) has a big dent in it used for filling much like potholes in out roads. They are called potholes because a pot (cookware) has a big dent in it used for filling much like potholes in out roads.
What does salt do to the ice on the road?
It eats into the road surface causing potholes. It lowers the freezing temperature of the ice and melts it away. See the related link for more information..
At the end of each winter roads are usually filled with cracks and potholes Why do you think this happens after cold winter rather than a hot summer?
In the winter the roads crack because the cold causes the concrete to contract, therefore making cracks and potholes in the road. This will not happen in the summer because the heat makes the concrete expand.
Does ice wedging often causes potholes in streets?
Ice wedging is not a common cause of potholes in streets. Potholes are typically formed due to a combination of factors such as weathering, traffic, and poor road maintenance. Ice wedging primarily occurs in natural environments where water freezes and expands in cracks in rocks or soil.
Would you find potholes in the roads of regions where temperatures are above freezing all the time Why?
Potholes can still form in regions with temperatures above freezing. When water seeps into cracks in the road and then freezes during the night, it expands, causing the pavement to crack and break. This process repeats and eventually creates potholes, regardless of the region's average temperature.
How do you use joggled in a sentence?
The road hadn't been paved in years, and the numerous potholes joggled the car. The word joggled is a verb.
When was Potholes in My Lawn created?
Potholes in My Lawn was created in 1988.
