The cracks form due to the forces applied by turning or braking motion of vehicles. Distortions in an asphalt pavement are caused by instability of an asphalt mix or weakness of the base or subgrade layers. These distresses may include rutting, shoving, depressions, swelling and patch failures.

What are the effects of road cracks?
This compression leads to cracks and fissures, which then become gashes and craters. Time. Once a small crack is created in the road, the more time that passes before it is sealed, the larger and more treacherous it can become. Traffic exerts continual pressure on cracked asphalt.
What causes the concrete on the streets to have cracks?
As the sun beats down on the concrete and then the night air cools it, the material goes through a cycle of expansion and contraction. These effects are small, but over time they can form tiny cracks in the concrete.
Is it normal to have hairline cracks in concrete?
Hairline cracks in a concrete slab are rarely a cause for concern. They can be controlled, but not eliminated. A crack in a slab of 1/8 inch or less is typically a normal shrinkage crack and not a cause for concern.
Are cracks in concrete normal?
When you see a crack in your concrete slab or wall, your first assumption is typically that something has been done wrong–but that's not always the case. Actually, concrete cracks are very common, some are even inevitable.
Why does concrete crack after a year?
Shrinkage is a main cause of cracking. As concrete hardens and dries it shrinks. This is due to the evaporation of excess mixing water. The wetter or soupier the concrete mix, the greater the shrinkage will be.
What is crack filling?
Crack filling is the placement of asphalt emulsion into non-working cracks to reduce water infiltration and to reinforce the adjacent pavement.
Does sealing concrete prevent cracks?
Protecting Concrete
A concrete sealer can reduce freeze-thaw damage by reducing the water absorbed by the concrete. ... One effective product that protects concrete from cracks is Sikagard 701W.
Can concrete cracks be repaired?
Wide cracks in concrete are best patched and sealed with a concrete patching compound. Smaller cracks, less than 1/4 inch wide, can be repaired with a concrete caulk or liquid filler. ... However, the color of the patch will look like new concrete and will not match the old concrete.
Should I worry about hairline cracks?
Generally, smaller hairline cracks are not cause for concern. These are usually the result of seasonal expansion and contraction of clay soils beneath your house over time, and can be easily patched and re-painted.
Should concrete crack right away?
As the shrinkage begins, the concrete will crack where it is the weakest. Cracking typically starts within 12 hours of the finishing process. Weather conditions will slow or accelerate it. Shrinkage cracking is typically planned for and handled with control joints.
Should concrete crack after pouring?
As the slab loses moisture while curing it gets a bit smaller. As the concrete shrinks, the slab could crack in order to relieve tension. Shrinkage cracks are common and can occur as early as a few hours after the slab has been poured and finished. Usually they are not a threat to the structure.
Can you pour new concrete over old cracked concrete?
You can put new concrete over old concrete. However, unresolved issues with your old concrete, such as cracks or frost heaves, will carry over to your new concrete if not taken care of. In addition, you must pour it at least 2 inches thick.
