摘 要:为了对道面养护管理者提供决策依据,建立了水泥混凝土道面预防性养护判定标准体系。基于路面抗滑性能评价指标与路面状况指数预防性养护标准研究成果,依据水泥混凝土道面衰变过程中平整度-动态荷载相互作用的基本理论,采用导数拐点法与混淆矩阵等模型研究了摩擦系数、道面国际平整度指数、道面破损指数与主导病害单项指标的判定标准。从判断性维度、综合性维度及控制性维度的角度对各个指标的作用与判定原理进行了分析,形成了军用机场水泥混凝土道面预防性养护判定标准体系。水泥混凝土道面预防性养护各项指标判定标准为:摩擦系数(跑道摩阻测试车95 km/h)≥0.41;摩擦系数(跑道摩阻测试车65 km/h)≥0.50;摩擦系数(摆式摩擦仪)≥0.51;国际平整度指数≤3.2 m/km;道面破损指数(3%~10%);边角剥落率≤35%;表面剥落率≤30%;表面裂缝率≤8%;板间错台率≤0.5%。该标准可为军用机场水泥混凝土道面预防性养护最佳时机的确定提供依据。In order to provide a decision-making basis for pavement maintenance managers,a judgment standard system for preventive maintenance of cement concrete pavement is established.Based on the research results of pavement anti-sliding performance evaluation index and pavement condition index preventive maintenance standard,and according to the basic assumption of the interaction between evenness and dynamic load in the process of cement concrete pavement decay,the judgment standards of friction coefficient,international pavement evenness index,pavement damage index and single index of dominant disease are studied by using the derivative inflection point method and confusion matrix model.This paper analyzes the function and judging principle of each index in the perspective of judging dimension,comprehensive dimension and controlling dimension,forming the judging standard system of preventive maintenance of cement concrete pavement in military airport.The results show that the criteria for preventive maintenance of cement concrete pavement are as follows:Friction coefficient(runway friction test vehicle 95 km/h)≥0.41;Friction coefficient(runway friction test vehicle/65 km·h^(-1))≥0.50;Friction coefficient(pendulum friction instrument)≥0.51;International flatness index≤3.2 m/km;Pavement damage index(3%,10%);Corner peeling rate≤35%;Surface peeling rate≤30%;Surface crack rate≤8%;And inter-plate slip rate≤0.5%.The cement concrete pavement of a military airport can be provided with this scientific basis in determining the best time of preventive maintenance.
