A crack occurs when water seeps into cracks in the pavement. It then freezes, causing the pavement to expand; when it thaws, the pavement contracts, causing cracks, which eventually lead to larger areas of cracking, pavement instability, and then potholes.
After know the reason of crack cause, then what should we do can prevent causing the cracks.
Cracks can be temporarily repaired in the winter, but because of pavement expanding and contracting due to the cold, it is recommended that permanent repairs be left until the spring.
It may be necessary to perform a full-depth removal of the affected area, depending on the damage. Luckily, the actual repair of a pothole itself is fairly easy; filling material is placed in the pothole, then it is pressed down and a cap is placed on it.
If you spot any fresh potholes, clearly mark them with a pylon. Then, contact your professional road maintenance manufactures for emergency repair right away; this will minimize your exposure to liability for trip-and-fall accident claims. Once the weather has warmed up, the professionals can repair the affected area with high-quality materials that will greatly extend the life of the asphalt pavement.
