Abstract

Purpose: The cavity exploration of the lower part of the road is carried out to prevent ground-sinking. However, the detected communities cannot be identified by the cavity location and history information, such as repackaging the pavement. Therefore, the field applicability of RFID systems was evaluated in this study to enable anyone to accurately identify information. Method: During temporary recovery, tag recognition distance and recognition rate were measured according to underground burial materials and telecommunication tubes using RFID systems with electronic tag chips attached to the bottom of the rubber cap. Result: The perceived distance and perceived rate of depth for each position of the electron tag did not significantly affect the depth up to 15cm, but it did have some effect if the depth was 20cm. In addition, water effects from nearby underground facilities and rainfall are relatively small, and the effects of wind will need to be considered during the weather conditions of the road. Conclusion: The RFID tags for field application of the pavement management system store various information such as location and size of cavity, identification date, cause of occurrence, and surrounding underground facilities to maximize cavity management effect with a system that can be computerized and mobile utilization.

연구목적: 본 연구는 지반함몰 예방을 위하여 도로하부의 공동탐사를 실시한 후 확인된 공동 중 포장층의 재포장 공사 등에 의한 공동 위치 및 이력 정보를 알 수 없게 되어 누구라도 정보를 정확하게 파악할 수 있도록 할 수 있는 RFID 시스템의 현장 적용성을 평가하였다. 연구방법: RFID 시스템을 이용하여 맨홀, 전력관, 가스관, 통신관 등 지하매설물 및 태그 종류에 따른 아스팔트 하부의 깊이별 인식거리와 인식율 등 임시복구시 고무마개 하단부에 전자태그칩을 부착하여 현장 적용성을 평가하였다. 연구결과: 전자태그의 위치에 대한 심도별 인식거리 및 인식율은 심도 15cm까지는 큰 영향이 없으나 심도 20cm인 경우 다소 약한 편이다. 그리고 매설물이나 강우 시 침수 등에 대한 영향은 적은 편이며 도로의 기상상황 특히 바람의 영향이 있어 측정 시 이를 감안하여야 할 것이다. 결론: 포장도로관리스템의 현장 적용을 위한 RFID 태그에 공동위치를 포함하여 공동에 관한 확인 일자, 공동의 규모, 발생원인, 주변 지하 매설물 등의 여러 가지 제반 정보를 저장하여 전산화 및 모바일 활용도 가능한 시스템으로 공동관리 효과를 극대화 할 수 있다.
