Abstract

This study focused on non-compacted rockfill in asphalt-paved internal roads, which is increasingly used in site grading works for the disposal of blasted rock, and reviewed the current design guidelines and construction specifications to discuss reasonable revision directions. As an introductory paper for a research project at its initial stage, this study aimed to establish the technical baseline upon which subsequent model tests and field trials for non-compacted rockfill will be designed. The current quality control framework for rockfill embankment, including KCS 11 20 20, KR C-04020, and the German DIN 18134, is fundamentally premised on compaction; non-compacted rockfill is largely outside these compaction-based frameworks. Although KCS 11 20 20 presents a gradation example for non-compacted rockfill in site grading and the Korea Land and Housing Corporation(KLH) design guideline 3.1.3 partially permits a rock finish of crushed rock (300 mm or less) within 1 m below the formation level for non-residential supply land, detailed construction and quality control criteria such as lift thickness, void management, bearing capacity evaluation, and long-term settlement control were found to be limited for non-compacted sections. Since the existing criteria are mostly based on compacted rockfill or road and railway applications, their direct extrapolation to non-compacted rockfill requires caution. For non-compacted rockfill, a behavior-based approach—using the repeated plate-bearing test (deformation modulus Ev2 and the Ev2/Ev1 ratio) and settlement monitoring, with criteria established through trial construction—was discussed as a candidate direction. The numerical criteria presented herein are not fixed values but should be established through model tests and field verification.
