| Abstract: | Using the Linear Track Accelerated Loading Facility System,12 types of direct track fullscale tests of asphalt pavement are carried out.The stress and response characteristics of the orthotropic bridge deck under dynamic load are discussed in this paper.And the causes that result in the two types of fatigue failure of the asphalt pavement are obtained through analyzing the results of the linear track fullscale test.In addition,the main problems in the nowadays design of asphalt pavement on steel bridge deck are presented and the suggestion to asphalt pavement design is given. |
