关于路面设计中参数的几点讨论

Some Discussions about the Parameters Regarding Road Pavement Design

随着道路工程相关新规范的修定，在路基路面设计过程中，怎样去理解新规范，并正确地选择设计方法和设计参数显得非常重要。文章主要针对《公路路基设计规范》（ＪＴＪ０１３－９５）、《公路水泥混凝土路面设计规范》（ＪＴＪ０１２－９４）、《公路沥青路面设计规范》（ＪＴＪ０１４－９７）中改变较大，设计中容易模糊的概念和参数，如：路基土稠度的概念和取值、水泥混凝土半刚性基层的回弹模量的取值和交通量与累计轴次的关系等进行了讨论。

With the newly-revised specifications concerning road construction adopted, it is very significant to correctly understand the new specifications and to accurately choose design ap- proaches and parameters. From the construction norms and codes such as 'Specifications for De- sign of Highway Sub-grades (JTJ013-95)', 'Specifications of Cement Concrete Pavement Design for Highway(JTJ012-94) ','Specifications for Design of Highway Asphalt Pavement(JTJ014-97 )', the author gives a great deal of consideration to some totally-changed or seemingly fuzzy concepts and parameters like the selection of value and conception of sub-grades earth's density and the value about the modulus of resilience of quasi-rigid sub-grades. The paper also discusses the re- lationship between traffic volume and accumulated load.
