New technology and construction methods in civil engineering area have been noticeably improved associated with the industrialdevelopment. However, thicknesses of a lift is strictly specified for subgrade and roadbed embankment as 20 cm and 30 cm in thespecification of Korea Highway. Since there has been a problem to get enough amount of soils to be used for compaction, the rockshave been replaced for those. However, there is no guideline for the quality control of rock while changing compaction efficiencyof equipment and physical properties of reck while changing compaction method such as thicknesses of a lift, number of compactionand etc. The main objective of this research is to establish the specification for the rock compaction method of embankment whichincluding thickness of lift and quality control method in Korea Expressway.
Abstract
