基于区间数法的水泥路面使用性能评价

公路在交通荷载和自然环境的共同作用下,路面使用性能会随着时间推移而日益衰减,从而直接影响车辆的行驶速度和运输的安全性、经济性和舒适性。为了评估和预测路面使用性能,便于进行科学的养护管理,根据现有的评价理论和方法,从指标数据代表的可靠性出发,建立了水泥混凝土路面使用性能区间数法的综合评价模型。最后,结合选取路段的实测数据与规范推荐评价方法进行了应用与对比分析,二者评价结果基本相同。该模型计算过程简单,易于编程,具有一定的推广和应用价值。

Evaluation of Concrete Pavement Performance Based on Interval Number Method

Under the long-term effect of traffic load and environment,the pavement performance becomes attenuation with time,which has direct influence on the driving velocity,safety and comfortability,as well as the transportation economy.In order to predict and evaluate the pavement performance,according to the current evaluation theory and method,a comprehensive evaluation model based on the interval number system method for the concrete pavement performance is established,which makes pavement maintenance convenien...
