  • Salt-frost deformation in highways of Xinjiang produces different degrees of damage with seasons every year, resulting in great economic losses. For understanding the laws of the disease development of city roads in saline soil areas, a long-term observation on the main city road of Alar is carried out. The observation data are summarized and analyzed, and some conclusions are drawn as follows: the city road diseases in saline soil areas have corresponding relationship with time, and the more obvious the road damage is, the longer the time is; larger traffic volume significantly inhibits the expansion of asphalt concrete pavement; the road diseases vary with the seasons and relate directly with the winter temperature; the road diseases gradually develop from the roadsides to the center of the road; the form of pavement diseases mainly includes cracking and raising, and cracking and raising usually occur together; the development of longitudinal cracks are more obvious than that of transverse cracks; there is water coming from the crack of the road centre in winter; the road cracks will eventually be connected with each other to form a mesh.
