军民合用机场混凝土道面表面特性一致性分析

Analysis of Military-Civilian Airport Concrete Pavement Surface Characteristics of Consistency

军航规范与民航规范的差异造成军民合用机场在设计和施工中存在分歧。针对水泥混凝土道面表面的设计和施工控制指标展开研究。从道面宏观和微观构造特征入手,结合现行规范分别讨论道面摩擦系数、纹理深度及平整度;从道面-胎摩擦系统出发,结合现场实测数据的回归公式对道面拉毛机理展开了分析;结合现场实测数据的对比、积水宣泄能力和耐久性探讨道面刻槽机理;利用实际数据建立了刻槽前后平均纹理深度h1和h2与道面摩擦系数f之间的回归公式。研究发现:平均纹理深度相较于摆式摩擦仪更适合用于水泥混凝土道面的现场施工控制,并提出了军民合用机场水泥混凝土道面表面的设计思路及施工控制指标。

Aimed at the differences of code for military aviation and civil aviation in design and construction of the dual-use airport, this paper proposes the several aspects as follows： Firstly,from the perspective of the structure characteristics of the pavement micro and macro, combined with the current specification, this paper respectively discusses the road surface friction coefficient, texture depth and flatness;Secondly, from the pavement-tire friction system, combined with the regression formula of field data the paper ana- lyzes road surface roughening mechanism, and combined with the field data contrast, water venting capaci- ty and durability, the paper analyzes pavement groove mechanism. The regression formula is established between the fore groove and rear groove with pavement average texture depth and the friction coefficient. The conclusion is that the average texture depth compared with friction pendulum instrument is more suit- able for the cement concrete road surface construction control. The paper proposes some design ideas and construction control index on the surface of the dual-use airport cement concrete pavement.
