The disaster controlling for highway engineering has a positive significance on the safety of highway. operation. There are shortcomings for the traditional controlling methods. The light-weight soil technique is a new method for controlling the highway engineering disasters and many outcomes have been obtained. Features and application history of light-weight soil are introduced and the feasibility of disaster controlling with light-weight soil is discussed. The study shows that the light-weight soil has such advantages as light weight, longevity, heat insulation and easy construction. It is concluded that the light-weight soil technique can effectively control the common disasters in highway engineering.
