几种不同填料用在沥青混合料中的生命周期评价

Lifecycle Assessment of Several Fillers in Asphalt Mixtures

通过剩余强度比试验,比较了几种填料在沥青混合料中使用的水稳定性能;并通过生命周期评价(Lifecy-cle assessment,LCA)法对几种不同填料在沥青混合料中应用的环境友好性进行了直观、科学的分析。作为一种难以处置的工业废渣,碱渣在沥青混合料中替代传统填料使用时,不仅可以提高沥青混合料的抗剥落性能,还具有重要的经济和环境效益。

Compared water stability of several fillers with residual strength experiments. The environmental-friendly characteristics of several fillers are analyzed in asphalt mixtures by the assessment of the lifeeycle （LCA）. The residue is an industrial waste difficult to be disposed. Residue can enhance antistripping of asphalt mixtures when used in asphalt mixtures as the filler. Compared with tradition fillers, the residue has more significant economical and environmental benefits than limestone in the asphalt mixture.
