摘　　要：采用年交通增长率和土基CBR两个指标,对灰色模型进行了修正,建立了大修后的机场沥青混凝土道面性能衰减模型,通过实例验证表明,该模型预测精度高,能客观反映机场柔性道面的性能衰减规律,满足机场道面养护工作的要求。The paper adopts the annual traffic growth ratio and soil matrix CBR, modifies the gray models, establishes the airport asphalt concrete pavement performance degradation model after the large-scale repair, and proves by the examples that the model can reflect the performance deg- radation law of the flexible pavement with high forecast accuracy and it meets the demands for the airport pavement maintenance.

关 键 词：沥青混凝土道面 灰色预测模型 预测精度 交通量
