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.

∙ 14y agoMost potholes are caused by weather. The rain water collects under the road. It freezes and causes a stress on the road. The cars driving over the stressed area brakes the pavement forming a hole.

Hope this helps

We will be filled with wastes.
What happens when a balloon filled with water is pricked with a pin?
The balloon pops and the water falls out and splashes onto the floor.
What happens to balloons when they are let go?
well it depends what type of balloon it is if it is filled with helium it will float higher and higher until it will pop under the air pressure. but if it a ballon filled with normal air it will just float back down or get blown away if there is wind
Explain what happens inside the ball when you pump a flat basketball?
The inside of the ball becomes filled with the air you pump in, thus inflating the ball and turning it from a flat ball to a round one.

What is a flooded crater?
A crater that is formed when there is an impact (usually by an asteroid) that forms cracks. The cracks are then filled by lava.
What are the advantages of an asphalt driveway?
Winter means snow. For many buildings, it means snow mountains and snow-filled walkways and driveways. If you own a commercial building, then you know that your driveway affects the general perception of your building. No one fancies a driveway filled with cracks or potholes. This holiday season, here are three things you can do to keep your driveway: Fix cracks. Asphalt expands and contracts when temperatures fluctuates. These cracks can create permanent damage on the driveway when water seeps into the foundation. Hire a contractor as soon as you can to fix these cracks. Clear the driveway regularly. Don’t allow accumulation of snow on your driveway. Snow can keep cracks hidden. It is important to shovel your driveway often so snow doesn’t worsen cracks or cause damages. Use Sealcoating.
Where can one get a glass tea pot repaired?
Repairing glass is not a simple task. Usually somebody like a glassblower will be needed. Small cracks can be filled with a resin material but usually it takes a pro to do it. Chinaglassrepair is a website that caters to this.
Why are there channels filled with tar at intervals across cement-concrete roads?
Where cracks form in the asphalt/concrete, repair crews fill the cracks with tar to keep water from seeping in and widening the cracks into pot holes.

Surface cracks can be easily fixed with elastomeric crack filler which is flexible. Deep wide cracks need to be filled with fine sand and then applied with the elastic crack filler.

What are potholes and what do the cause?
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 equal 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. Further more, 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 cracksCars 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 rof potholes with coldpack asphalt. If the material is not installed properly (bonded in palace with tar and tamped and rolled intp 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 whre the surface is weakest, the site of the poor repair.
What is the difference between a pothole and sinkhole?
A pothole is a hole in a street caused by traffic and weather. It is caused by events above the street. A sinkhole is caused when land beneath the street is washed away or water empties out of a cave from beneath a street. In that case, the street falls down into the hole created when the road collapses when the ground gives way. Potholes are far easier to fix than sinkholes. Potholes need to be filled in and they are ready to be driven over. With sinkholes, the underlying problem must be filled in or the road must be rerouted. After the sinkhole is filled in or the road rerouted then the road must be rebuilt.

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.
