The Impact Temperature Has on Paved Asphalt
When people see asphalt, they believe it is something very strong. This is true, but asphalt also has its shortcomings. When the seasons change, it is obvious the changing temperatures do affect an asphalt surface.
There are many places that experience significant low temperatures during the winter. This could result in freezing occurring above as well as below any asphalt surface. Any water that has penetrated the asphalt surface can freeze. This can cause cracks to occur. When this happens during the winter months, it could cause problems with an asphalt surface. Since water expands when it freezes, the more water that fills the cracks can result in the beginning stages of a pothole.
Areas that regularly have warmer weather can experience asphalt affected by extreme heat. Cracks can be caused by the heat, and this will result in water getting into the asphalt. This can damage asphalt. Water drainage can erode the subsurface layers beneath an asphalt surface. It will cause air gaps to form inside the pavement. Should the surface with air gaps have pressure placed on it, the subsurface will sag and possibly collapse.
Rain And Asphalt
Rain is something that can occur more at certain times of the year. Any cracks in asphalt can result in potholes because of rain. Any water that penetrates the asphalt surface has the potential to result in significant problems. An asphalt surface located at steeper elevations can be slowly washed away over time. In some situations, this has resulted in bare rock where the asphalt surface was once located. Liquid asphalt is what will wash away. It is a product with a petroleum base and is utilized to bond rock and stone to form the asphalt surface.
Changes in temperature and the weather can significantly impact any asphalt surface. It is possible to take steps to prevent damage. This can be accomplished by placing a sealant on the surface of the asphalt every few years. Once this is done, it will help prevent water from getting to the subsurface of the asphalt. This will provide an important layer of protection against the problems caused by extreme temperatures.
When holes or cracks are discovered in an asphalt surface, they need to be immediately repaired. They are not appealing and could provide a safety hazard for any vehicle or person traveling on the asphalt surface. Even the smallest crack or hole will only become worse over time.
The strength and durability of an asphalt surface are known by many. When it is properly maintained as well as repaired, it is able to be used in a variety of ways. An asphalt surface is designed to last for a long time.
