Abstract

PET aggregates were produced by mixing heated PET flakes with frictional soils. Using these artificially-made PET aggregates, horizontal drain tests in the laboratory, pilot scale model tests were conducted for the evaluation of the drainage characteristics of PET aggregates. Laboratory horizontal drain tests were conducted under twenty different conditions varying mixing ratios and surcharged pressures. Moreover, by utilizing the aggregates with a mixing ratio producing the lowest variation in terms of permeability against applied load, large scale tests were performed. Reliability of the test results was evaluated from comparison with the results of the laboratory horizontal drain test.

PET 인공골재의 배수특성 평가를 위하여 실내 수평투수실험, 실대형 수평투수실험을 실시하였다. 실내 수평투수실험은 PET 골재의 생산량에 따라 세 종류의 입도별로 분류하고, 분류된 PET 골재를 정해진 배합비에 의해 20가지로 분류하여 단계별 하중을 재하하면서 실시하였다. 또한 실내 수평투수실험에 의해 분석된 결과를 활용하여 재하하중에 따른 투수계수의 변화경향이 가장 적은 실험 유형의 배합비로 실대형 수평투수실험을 실시하였고, 실내 수평투수실험 결과와 비교하여 신뢰도를 평가하였다.
