Accordingly, central government partially revised <Special Act On The Safety Management Of Structures> with the contents of expansion of 2nd class facility's scope and standard and it is expected to be an effective maintenance and management measures of cut slope.
Therefore, this study analyzed distribution type and characteristics of the national highway cut slope within the scope of relevant laws and regulations based on the status data of 2nd class facility (cut slope) to examine the maintenance status.
