초록

최근 집중호우, 잦은 강설, 급격한 기온차이 등 환경변화의 가속화에 따라 균열, 단차, 포트홀 등 다양한 형태의 도로 파손이 급증하고 있다. 이중 포트홀 관련 사고는 파손 특징상 대형사고를 유발하며 08년 기준 5년간 약 5배 이상 증가하였다. 매년 포트홀로 인한 인명피해, 차량파손 등 직 간접적인 피해가 증가함에 따라 보다 신속하고 효율적인 관리 대책이 필요하다. 따라서 본 연구에서는 포트홀 규모, 면적과의 상관관계를 통해 체적 보정계수와 보수재료 물량산출 알고리즘을 제시하였다. 제시된 물량산출 알고리즘의 검증을 위해 수도권 지역 15개소의 포트홀을 측정한 결과 통상적으로 개소당 약 5~7 kg까지 발생하던 재료 잔량이 1~2 kg까지 감소하는 것으로 나타났다. 작업자의 주관적인 판단에 의존하여 시공하고 있는 실정에서 포트홀 체적 감지 자동화 통합시스템은 재료/자원 절감뿐 아니라 적정한 보수물량 산정을 통해 다짐상태 등 포장 품질향상에 기여할 수 있을 것이다.

Various type of pavement deterioration such as crack, bumpy, pothole is rapidly increasing according to the accelerated environmental changes like heavy rainfall, frequent snowing, difference temperature, etc. Accident related to pothole that cause fatal traffic accidents has been increased more than five times over the next five years starting from 2008. As direct or indirect damage by pothole which caused injuries and car damages increases every year, quicker and more efficient management measures are necessary. This study presents the algorithm for materials quantity take-off. The algorithm was suggested by correlation in pothole size and area. Suggested algorithm were confirmed the validity through the 15 field survey in capital area. According to the results of survey, usually the residual materials at which 5~7 kg was generated decreased to 1~2 kg. It showed that automatic pothole detection system is expected not only to reduce materials and resources, but also to contribute to quality improvements of pavement through more accurate material take-off from the situation of constructing rely on their own judgement.
