| 摘要： | The U.S. Navy and U.S. Army together own over 5700 miles of railroad track that are vital to the mobilization and operational needs of the Department of Defense. Civilian local railroad companies control another 19,000 miles. Track managers need a method to assess current track conditions, predict future track conditions, establish track deterioration rates, formulate budgets, and determine and prioritize renewal projects. In response to this need, the U.S. Army Construction Engineering Research Laboratories developed track component group condition indexes based primarily on visual inspection surveys and supplemented by inspection and operating criteria from various track standards. This manual provides track inspectors with a standard reference for identifying track distresses and calculating condition indexes. |
