| Abstract: | The data of temperature and strain of asphalt pavement were measured.Based on comparing the calculated strains and pavement mechanical models,the pavement mechanical model and parameters which can agree with the actual pavement more closely was studied.Furthermore,the interface continuity conditions of different types of pavement and the amendment method of calculated pavement mechanical parameters was studied.It is found that(1) multi-layer elastic model using dynamic modulus is the better choice for pavem... |
