摘　　要：建立了沥青路面GM(1,1)预测模型,并对该模型的预测精度进行了分析。结果表明灰色系统理论适合于预测沥青路面相对弯沉,解决实测周期长的难题。The forecast model GM （ 1,1 ） for asphalt pavement has been established and forecast accuracy of present model analyzed. Results makes clear that theory of grey system is acceptable for forecast of relative deflection of asphalt pavement, which solves difficult problem of long observational period.

关 键 词：相对弯沉 灰色理论 GM(1 1)模型
