车辆在路面有水膜的道路上行驶时，轮胎与路面的附着力会随着水膜深度的增加而减少。为了研究道路路面的水膜厚度在降雨条件下的变化情况实地测量路面水膜深度,通过测试数据与水膜深度预测模型的计算值经行对比,评价分析了Gallaway模型、PAVDRN模型和RRL模型3种水膜深度预测模型。研究表明,国内外既有的预测模型中有几种成熟的路面水膜深度回归模型预测精度比数学物理模型高，RRL模型与Gallaway模型和试验测得的数据之间差异较小;参数具有一定的差异,主要是由于实验条件对标定回归模型的水膜深度的影响较大,降雨使路面产生水膜时,对路面摩阻系数产生影响的水膜应该以包含了道路构造深度的平均水膜深度为表征,而不是消除路面构造深度中的路面水膜深度。

Answer 1

Vehicles on the road there are water film of the road, the tire and road surface adhesion will reduce with the increase of the depth of the water film.To study the water film thickness of road surface under the condition of rainfall changes in field measurement of pavement depth of the water film, through the test data and the depth of the water film prediction model and the model, the value of evaluation Gallaway model were analyzed, PAVDRN model and RRL model three kinds of water film depth prediction model.Research shows that the existing prediction models at home and abroad several mature pavement depth of the water film in the regression model prediction accuracy is higher than mathematical physical model, RRL model with Gallaway model and little differences between the data measured in experiment;Parameters have certain differences, mainly because of experimental conditions on the depth of calibration regression model of water film is larger, the influence of rainfall makes the road when the water film, impact on road surface friction coefficient of the water film should be to contain the way the average depth of the water film for characterization, structure depth rather than to eliminate pavement structure in the depth of pavement depth of the water film.
