Abstract


Temperature field and thermal stress analysis of asphalt pavement structure can not be separated from the thermal properties of the material parameters , the thermophysical parameters change with temperature condition and the type of material , but in the past during the analysis of the temperature field and thermal stress of the pavement structure , the general the thermophysical parameters of the material taken as a given value , so that the estimated temperature field and temperature stress calculation correctness greatly reduced. The road structure is changing the temperature of the environment , so if you want to accurately simulate the road structure temperature field , road materials thermophysical parameters measured under different conditions is very necessary . Thermophysical parameters mainly include research contraction coefficient of specific heat capacity , thermal conductivity , and lines . Main research content and research conclusions are as follows : development and calibration of the asphalt mixture than the heat capacity of the test system , test the asphalt , aggregates , asphalt mix material 's specific heat capacity , derived asphalt mixture each component of its specific heat capacity , through the forecast application of model than the election parallel model specific heat capacity forecast for asphalt mixture . Prediction model than with rapid thermal conductivity measurement instrument to test the asphalt , aggregates , asphalt mixture thermal conductivity derived asphalt mixture of the components of its thermal conductivity ; analysis of the temperature variation of the thermal conductivity ; the election draw applications in parallel model for asphalt mixture thermal conductivity coefficient estimates . The strain gauge electrical measuring method , determination of the coefficient of linear shrinkage of the asphalt mixture , derived asphalt type of impact is greater than the porosity and aggregate mixture of linear shrinkage coefficient ; temperature changes and temperature and speed changes affect the linear shrinkage coefficient larger. Pavement temperature field estimated using the finite element model , with the the pavement measured temperature contrast , come if you want to accurately simulate the temperature field of the road structure , thermophysical parameters measured under different conditions of road materials .
