dc.description.abstract본 연구에서는 아스팔트 포장의 표층을 구성하고 있는 아스팔트 혼합물의 점탄성(Viscoelasticity) 거동을 규명하기 위하여 먼저 기존의 일반적인 역학적 모델을 고찰하였으며, 차량의 단일 축 하중을 고려한 점탄성 모델식을 제안하고 그 모델에 대한 기본식을 유도하였다. 또한, 제안된 모델식의 검증을 위해서 시험구간에 대하여 비파괴시험을 실시하였으며 하중 이력에 따른 변형률과 처짐값을 산출하고 이를 제안된 모델식의 계산값과 비교분석하였다. 분석 결과, 시험값과 모델식의 결과값의 오차가 거의 없음을 알 수 있었으며, 시간에 따른 처짐의 양상만을 비교해 볼 때, 본 연구에서 제안한 모델식에 의해서 실제 하중에 의한 포장의 처짐을 예측하는 것이 가능하다는 결론을 얻을 수 있었다.-
dc.description.abstractExisting basic mechanical models which are methods characterizing viscoelastic materials were first reviewed to account for viscoelastic behavior of the asphalt pavement structure in this paper. A viscoelastic mechanical model considering a single load of vehicles subsequently was suggested and an equation that indicates the time-dependant behavior of asphalt pavements was derived from the proposed model. Non-destructive tests using falling weight deflectometer(FWD) were performed for a test section to estimate the application of the model. Both deflections and strains procured by the equation were compared to testing results according to loading history. By observing field measurements and theoretical evaluations, if two results are compared by the features of deflection according to time history, it could be concluded that the proposed model is expected to be suitable for prediction of the behavior of asphalt pavements because there is hardly difference between field data and calculated data.-
