Asphalt need asphalt box to preservate heat in the production and use process,if stored appropriate, asphalt can repeated heating namely its performance won't be damaged badly under higer temperature keep a very long time,So, the asphalt box's performance is very important, in this paper, the mechanical properties of the material was considered, the FEA model of asphalt box was be setted up,the stress and strain of unloading entrance was be analysed when in the 4g longitudinal accelerated speed and a standpoint was be determined that the structure performance of asphalt box is Meets the related standard requirements.
