Abstract

Currently, the quality measurement of the work is carried out by the supervisor's visual inspection, as the workers individually judge the number of resolutions, thickness, speed and vibration. After work, we are conducting follow-up work through traditional spot test, which is less representative. Therefore, it is impossible to check the results of the resolution, and there is always the possibility that problems will arise due to poor construction. This study demonstrates the feasibility of using the continuous compaction strength measurement method by comparing the continuous compaction strength measurement method and the conventional compaction strength measurement method after performing the compaction in the actual field scale in various test conditions. The validity is verified by analyzing the Compaction Meter Value of an Intelligent Compaction roller composed of a Global Positioning System and an accelerometer, Based on the proven results, a full range of quality can be confirmed without a single test. The quality confirmation is visualized in the compaction control program developed in this study, This enables the field manager to perform real-time quality monitoring at the same time as compaction.

현재 다짐공사는 작업자가 정해진 다짐횟수, 두께, 속도, 진동여부 등을 자신의 경험에 의해 개별적으로 판단하고 감독자의 육안 검사에 의해 다짐공사의 품질측정이 이루어지고 있으며, 작업 후 대표성이 떨어지는 재래식 다짐강도 측정방법인 일점시험(Spot test)을 통하여 후속 단계의 작업을 진행하고 있는 실정이다. 따라서 다짐작업 결과에 대한 정량적 확인이 불가능하며, 시공부실로 인한 문제점이 제기될 가능성이 상존하고 있다. 본 연구에서는 여러 가지 시험조건에서 실제 현장규모로 다짐을 수행한 후 연속 다짐강도 측정 방법과 재래식 다짐강도 측정 방법과의 비교를 통해 연속 다짐강도 측정 방법의 사용 타당성을 입증하였다. 타당성 입증은 연속 다짐강도 측정방법인 GPS (Global Positioning System)와 가속도계로 구성된 IC (Intelligent Compaction) 롤러의 CMV (Compaction Meter Value)를 분석하는데 있으며, 입증된 결과를 토대로 일점시험을 배제한 현장 전 범위 품질확인이 가능하다. 품질 확인은 본 연구에서 개발한 다짐공사 관제프로그램에 시각화되며, 이를 통해 현장관리자는 다짐작업과 동시에 실시간 품질 모니터링이 가능하다.
