Background of the asphalt pavements issues
• Background of the asphalt pavements issues. • Definition of thermal cracking in pavement and the mechanism. • Possible causes of thermal cracking; for example in hot weather and cold weather. • How does thermal cracking related to the temperature? • What are the bad effects of thermal cracking? • How can thermal cracking be solved or maintained? • The cost of maintaining and repairing thermal cracking.• How can we avoid thermal cracking issue?• What is the right grade should be used, and how does it relate to the temperature? PG• Provide some examples of thermal cracking.
