Abstract

Pavement management systems (PMS) provide procedures to quantify road serviceability based on pavement conditions such as cracks and plastic deformation and suggest proper maintenance methods. The deterioration of the road pavement is relevant to the time although the quantifications on road serviceability in PMS present road surface conditions at the evaluation. More systematic evaluation on road serviceability may need time-dependent factors of road environments and that can improve PMS. Rainfall, temperature and vehicle loads can be environmental factors for road serviceability evaluation. As no data are avablie that can link between road conditions and environmental road factors, we conducted experiments to suggest economical devices and methods to obtain relevant data. We used temperature sensors and accelerometers with Arduino to measure road surface temperature and dynamic loads and provide data to improve pavement serviceability evaluation.

도로관리시스템(PMS)은 균열, 소성변형 등 포장상태를 정량적으로 평가하여 도로공용성을 산정하고 유지보수를 진행한다. 도로관리시스템의 도로공용성평가는 당시의 도로표면상태를 나타내지만, 도로상태는 시간에 따라 악화된다. 체계화된 도로공용성평가는 도로환경에 대한 시계열 인자가 포함되는 것이 필요하고 그것이 도로관리시스템을 향상시킬 것으로 보인다. 강우, 온도, 차량 하중 등이 도로환경인자가 될 수 있다. 현재는 이러한 인자를 측정하고 상관관계를 나타낸 자료가 없으며, 실험을 통해서 경제적 장비를 제작하고 자료를 얻는 방법을 제시하고자 한다. 여기서는 온도와 차량하중을 고려하기 위해 온도계측과 가속도계측을 시도하고 도로공용성 평가법을 개선하는 데 필요한 자료 제공방법을 제시하였다.
