[0002] At present, most of the special semi-trailers used for hot asphalt mixture transportation have poor sealing performance, and the whole vehicle does not take any insulation measures or only installs insulation cotton for insulation. Due to the high thermal conductivity and fast heat dissipation of steel structure, the vehicle insulation performance is poor. In the low temperature season, long-distance transportation operations are prone to low-temperature segregation and solidification of asphalt mixtures, which affects the overall performance of the construction road surface. In addition, special semi-trailers engaged in the transportation of bulk granular materials such as hot asphalt mixtures and sand and gravel need to be weighed before and after loading to determine the weight of the loaded materials.
