摘　　要：为了保证干线公路的使用品质,降低养护成本,针对干线公路的小修保养策略及施工规程进行了研究,通过结合江苏省干线公路路面状况现场调查结果,引入典型病害单项评价指标,构建了PCI多级评价体系,为合理界定养护等级制定路面养护维修方案提供了依据,实践表明,该方法具有较强的针对性,可为路面养护决策提供参考依据。For the reason that the evaluation results of the current road conditions can not reflect the actual quality of road use accurately.This paper combined with the field survey of the highway pavement condition in Jiangsu Province and constructed PCI multistage evaluation system by introducing the single evaluation indexes of the typical disease.By doing this,it provides the basis for defining the maintenance level reasonably and making the pavement maintenance plan.Practice shows that this method has strong pertinence.Therefore;It can provide a reference for pavement maintenance decision.
