Asphalt Paving Design - cdn.ymaws
Asphalt pavement is a flexible pavement allowing it to withstand occasional over-loads without serious damage. Its resistance to freeze-thaw and deicing salts provides for superior performance during inclement weather. Its lack of repetitive joints removes the possibility of the blowups that plague Portland Cement Concrete during summer heat waves.
