2003年12月中下旬，三一重工股份有限公司研制的LH25运输机在江西

In the middle and late December 2003, the LH25 transport aircraft developed by Sany Heavy Industry Co., Ltd. was put into use on the Changjin Expressway in Jiangxi Province. The whole process of construction adopts the double-paver trapezoidal operation method. One side uses a transfer vehicle and the other side does not use it. <br>For comparative tests, this paper has conducted experimental research from three aspects: material segregation, temperature segregation and pavement smoothness.
