When the temperature exceeds 38°C, the rutting depth will be very large; if the temperature exceeds 40°C continuously, the road surface will be seriously damaged by rutting. This will not only affect the flatness of the road surface and reduce the smoothness of vehicle driving, but may also become an important safety hazard on the highway; especially when large trucks pass by, if the high-temperature asphalt pavement exceeds 50° and is crushed by large trucks, it is easy to cause damage to the road surface. Therefore, a series of measures need to be taken to reduce the temperature of the asphalt pavement, such as using awnings, sprinkling water to cool down, etc.
