充分考虑高速公路行车特点及对路面使用性能的要求 ,利用河北省高速公路的调查数据 ,分析目前养护规范评价模型在高速公路应用中的不适之处 ,提出应建立能正确反映高速公路使用性能的评价模型结构体系 ;并在原有路况指数模型的基础上 ,增加独立的车辙模型和车辙、破损二元模型。 Taking full consideration of the characteristics of expressway driving and the requirements of pavement performance, this paper analyzes the present discomforts of the evaluation model of conservation standard in expressway application by using the survey data of expressway in Hebei Province, and puts forward that we should set up a model that can accurately reflect the performance of expressway Evaluate the structural system of the model; and add the independent rutting model and the rutting and breaking binary model based on the original road index model.
