STUDY ON QUALITY CONTROL METHOD OF EMBANKMENT USING GPS

The quality control of an embankment for an expressway has been executed through field-density measurement by a sand replacement method. The method, however, requires a great deal of labor and time. Therefore, it is difficult to reflect the results of measurement to construction work promptly. As a result, a transmission type of radiation gauge (RI) that can quickly measure the field-density at a number of points has been used since 1985 for a quality evaluation and increased work efficiency. However, an execution ability increases with the introduction of large machines, establishment of further efficient quality control method is expected. A system that can obtain two-dimensional information for a car using a global positioning system (GPS) is already in practical use, and the technology is being applied to compaction control. The three-dimensional position of compaction equipment and the thickness of finish layers can be obtained in real time by operators themselves or construction managers by utilizing the vertical information (Z coordinate), reliable compaction work is guaranteed and it is conceivable that the quality control is improved. The Japan Highway Public Corporation performed a field test to study applicability of compaction control using GPS. This paper describes the viewpoints of embankment construction and changes in quality control methods in Japan. Results of field tests by the quality control method using GPS are also reported.
