Application of Road Compaction Quality Control System to Road Pavement Construction for Advanced Quality Control

Japan is undergoing a social transition with a decreasing workforce in the construction industry; therefore, improving productivity is an urgent issue for sustaining social infrastructure. This paper presents a quality control system for road pavement construction, relying on non-destructive and automatic measurement for compaction quality control. The system’s applicability and measurement accuracy were verified in 2020 and 2021 for national highway pavement construction, commissioned by the Ministry of Land, Infrastructure, Transport and Tourism. The system is labor-saving and has equivalent accuracy to the currently used transmission RI for compaction quality control. This paper reports on an overview of the verification.
