A high proportion of JNR's lines are laid on earth structures such as embankments and cuts. Earth structures are comparatively inexpensive and easy to repair or restore in the event of natural disasters. On the other hand they are subject to subsidence and mud pumping under the heavy rainfall conditions frequently occurring in Japan, and thus require considerable maintenance work. Because of a tighter labor situation, frequency and density of traffic and higher standards necessary for high-speed operation, JNR has developed two kinds of reinforced roadbed, which are described in this article.
