摘要
京津塘高速公路于为收费公路。其主要路线为北京—廊坊—天津—塘沽。是我国国内第一条按照国际标准兴建的现代化交通工程。它的建设,打开了首都直达天津港口的快速通道。但同时,我们也发现,其中有些高速公路路段的路面结构在运营早起就发生了破坏。柔韧性路面由于平整度好、行车舒适、噪声小、易于维修、对路基变形的适应性强等特点而逐渐成为新建高速公路主流路面结构。但由于车辆超载及动载作用,使的有些沥青路面仅仅2~3年就出现了断裂,翻浆,沉陷等不良状况。
目前我国经济建设和社会发展取得举世瞩目的成绩,这离不开国民经济最重要的基础设施之一的高速公路,做好公路设计工作,有利于公路事业不断发展,有利于实现良好的交通环境,促进社会和国家经济的快速前进。因此,针对高速公路的长期性和持久性进行路基路面结构综合设计优化势在必行。
本文运用文献资料法,对国内外高速公路发展现状进行调查,并对调查结果进行深入分析。在借鉴高速公路相关理论知识的基础上,参阅国内外大量专家关于高速公路建设发展的研究成果,对京津塘高速公路建设发展现状进行调查、分析并深入研究。根据沿线地区收集的地质、水文及气象资料,选择路线方案、参考已有工程拟定尺寸、不同的结构形式,根据《公路工程技术标准》及《规范》进行不同内容的验算、采用CAD软件来绘制路线平面设计图、路面纵断面图、路基横断面图。

Abstract
Tianjin-Tanggu Expressway toll road . The main route for Beijing - Langfang - Tianjin - Tanggu . Is our first domestic built according to international standards of modern traffic engineering . Its construction , direct access to the fast-track to open in the capital of Tianjin Port . However , we also found that one section of the highway pavement structure is somewhat early in the operation took place destroyed. Due to the flexibility of road roughness, fort , low noise, easy maintenance, strong adaptability to the roadbed deformation characteristics gradually e the mainstream of the new highway pavement structure . However, due to overloading and dynamic loads , so that some of the asphalt pavement is just 2 to 3 years there have been broken, boiling , subsidence and other adverse conditions .
At present, China 's economic construction and social development has made remarkable achievements , which is inseparable from the highway , one of the most important national economic infrastructure , good road design work is conducive to the development of highways , is conducive to good traffic envi
