道京承線病害調(diào)查改

1、省道京承線相關(guān)資料首先，這兩本規(guī)范一定要好好看看。尤其是規(guī)范一 .要熟悉舊路檢測都要進行哪些項目的檢測。(1)公路技術(shù)狀況評定標準(JTG H20-2007 )(2)公路工程質(zhì)量檢測評定標準(JTG F80/1-2004)公路狀況本項目的編制范圍是省道京承線巴克什營一平坊段，起訖點樁號 K0+000K28+562 ,全長28.562公里，途經(jīng)火斗山鄉(xiāng)、拉海溝。原道路等級 為三級，其中 K0+000-K0+075 段，路面寬12米；K0+075K1+000 段為漸變 段，寬度為12米7米。K1+000-K28+562 路基寬7.5米，路面寬7米。設(shè)計 彎沉值為 30.4(1/100mm)原路面結(jié)
