【摘要】 为了能够简捷、直观地揭示、评价再生沥青的老化性能 ,建立了以正戊烷沥青质为参数的老化动力学模型。通过考察老化过程中正戊烷沥青质含量的变化 ,计算得到了有关动力学参数 ,建立了老化动力学模型。通过考察老化过程中反应的活化能 ,比较了再生沥青以及原沥青的抗老化性能。更多还原

【Abstract】 The aging kinetic models in the parameter of n-pentane asphaltene is derermined for simply discovering the anti-aging property of regenerated asphalt. By means of exploring the change of the content of n-pentane asphaltene when the regenerated asphalt aged, we can attain the kinetic parameters by calcaulating.By means of exploring the activation energy when it aged, the anti-aging property of the regenerated asphalts and original asphalt are compared.更多还原
