Abstract: Based on the essences of asphalt pavement performance,a comprehensive quantitzed norm CSI is put forward to de-scribe the property. Thus, the bituminous pavement design is carried to a new field. In addition, some problems arisingin the structural edsign of asphalt pavement with the aid of CSI and the possible ways of solving them are discussed,too.

Key words: asphalt pavement, performance, index, membership function, structural design

摘要： 本文根据沥青路面结构使用性能的内涵，确立了表征使用性能的综合指标CSI，并对其进行了量化分析，从而，进入了沥青路面设计的新领域。此外，文中还探讨了CSI指标用于控制沥青路面结构设计尚需解决的问题及途径。
