초록

본 연구의 주 목적은 최근 증가하고 있는 과하중 트럭의 운행에 대한 도로의 성능 평가에 대한 역학적-경험적 가이드라인을 개발하는 것을 목적으로 한다. 본 연구에서는 두 가지 가이드라인을 제시하고 있다. 첫 단계 가이드라인은 도로 평가 도표를 이용하여 최적의 도로경로를 찾고 그 도로에 대한 추가 실험이나 분석이 필요한지 판단하는 기능을 하고 있다. 그 다음 단계에서는 OTRA 프로그램을 이용하여 도로가 과하중 트럭의 운행이 지속된 공용 기간 동안 구조적 성능을 발휘하는지에 대한 검토를 하고, 또한 필요하다면 아스팔트 덧씌우기 층두께를 산정할 수 있는 기능을 갖고 있다.

The main objective of this research is to develop the Mechanistic-Empirical (M-E) guidelines for evaluating the capacity of existing highways to sustain route overweight truck traffic over a specified performance period due to a growing concern on the impact of increasing overweight truck loads on highways. In this study, a two-stage framework was developed for this purpose. Level I procedure involves the use of pavement evaluation charts to identify the best possible route from among the alternatives considered and to determine what additional tests and analyses are needed as a screening tool. Level II involves the application of the Overweight Truck Route Analysis (OTRA) program to evaluate the structural adequacy of an existing route to carry routine overweight truck traffic over the specified performance period along with estimating asphalt concrete overlay thickness, if necessary.
