In this paper, finite element program, MSC.NASTRAN was employed to analyze structural responses of three-dimensional simplified pavement models of low volume pastoral roads under the quiescent loads. Firstly, the models with three load positions have been put forward according to traffic investigation. Secondly, effects of the road shoulder materials, the curb and thickness of wearing course on structural response of the pavements were studied. Finally, the test roads were constructed and detected in Inner Mongolia prairie, and typical pavement structures for low volume pastoral roads were recommended.
