AI Technical Summary
During the transportation and paving of hot-mix asphalt, temperature segregation can occur due to temperature differences, especially when the asphalt comes into contact with the hopper wall in windy weather. This causes the edge asphalt temperature to drop, leading to segregation.
Asphalt is uniformly fed in using a material homogenizing device, and external wind is shielded by auxiliary devices. The temperature of the asphalt material is monitored and compared in real time using a monitoring device. Electric heating plates and insulation layers are used to maintain temperature uniformity and prevent segregation caused by excessively low edge temperatures.
It effectively prevents temperature segregation during asphalt paving, improves the practicality and efficiency of the equipment, reduces the impact of external wind on the material, and ensures paving quality.
