摘要
随着我国经济高速发展,作为新疆省经济文化中心,乌鲁木齐逐渐成为了我国同中亚等邻国交流的重要交通枢纽。由于乌市特殊的地理气候条件,城市道路往往易发病害。本文通过乌市典型道路的病害调查,分析了乌鲁木齐道路病害的组成情况、高发类型及病害原因;进行结构强度调查,分析了龄期、结构类型等对乌市路面强度的影响;由芯样调查,分析了乌市服役路面的级配变化和空隙率情况。为后续建设工作提供了参考。
With China's rapid economic development,Urumchi,as the economic and cultural center of Xinjiang Province,has gradually become an important transportation hub for the communication between China and central Asia.For the special geographic and climatic conditions of Urumchi,highway damages are frequently occurred.In this paper,through damage investigation of typical highway in Urumchi,the composition,frequently-occurred damage and causes of highway damages are analyzed;through structural strength investigation,the impact of age and structural type to pavement strength in is analyzed;through core sample investigation,the gradation change and voidage of highway pavement in service are analyzed.The results can provide preference for following construction.
