Freezing and thawing cycle that causes potholes in roads and breaks in rocks?
Freeze/thaw cycle doesn't create potholes. It creates cracks on pavement. Potholes form when water, whether from melting snow, rain or frost thawing gets into the cracks in the pavement and cause the road base to shift and develop voids just under the pavement. When this occurs, the weight of vehicles causes the pavement to crumble causing potholes.

Why do paved roads damage more in the winter rather than in the summer?
Freezing, and ice wedging. Water freezes and refreezes expanding under the road and in the cracks.

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.
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.

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.

Why do roads need to be sealed?
To seal the surface and prevent rain water seeping into the road material. In winter this water will freeze and potholes will appear when the weather warms up in spring.
Which city has the potholes in the us?
Having driven in many cities in the US I would have to say that Detroit Michigan has some of the worst roads in the country. I drive a lot in the state of Oklahoma. In Tulsa, the roads are really bad and uneven. Potholes there range anywhere from 1' to 6' in diameter and up to 2' deep in some places. Those potholes are just the ones located on paved roads. Some dirt or gravel roads have had up to half of the road missing after a big storm."During the fiscal year 2000-01, 83,613 potholes were repaired." That was from a report given by the city, on the conditions of roads in Tulsa. Those numbers, however, are just an estimate of the potholes that have been reported as repaired according to city maintenance records. There are still more potholes that haven't been reported, fixed, or are on roads that the city isn't responsible for maintaining.

What often causes pothpoles in streets?
Potholes are holes created in the road due to various stresses. On tar roads, the tar can expand and contract considerably during the summer and the winter. As a result of this constant contraction and expansion, parts of the road can erode away. During the winter, ice can also form in the pores in the tar road and the freezing of the ice expands the road slightly. Over days, weeks, and months of exposure to such stresses, tar roads break away at weak points and form potholes. Continued driving and application of the weight of multiple cars and trucks can also facilitate the road's destruction. The same can occur on concrete roads, although not as often as on tar roads.
