Abstract

This study analyzed the field applicability through the combination of environment-friendly grid-typed reinforcements and pre-mixed fiber with filler. The film of the grid-typed reinforcement is made by recycled PE resin. And, Ascon fiber is obtained the dispersion by pre-mixing of filler. To be able to recognize in advance the various circumstances that could arise in the construction of the road pavement layer, we conducted a basic field application test of the (Mock Up) pavement layer. As a result, it was found that the pavement with environment-friendly grid-typed reinforcement and dispersive fiber construction had improved strength, stress, and rutting resistance. It is consistent with the strength and stress results of the actual test of the mock up specimen. It is expected to perform an effective role in the safety as well as the use of environment-friendly fibers in actual construction.

본 논문에서는 재활용 필름을 사용한 친환경 그리드형 보강재와 사전에 충진재의 혼입을 통해 분산성을 향상시킨 섬유를 도로 포장층에 복합적으로 적용한 공법의 현장 적용성을 분석하였다. 그리드형 보강재를 구성하고 있는 필름은 폐기된 PE수지를 재활용하여 친환경성을 강조하였고, 아스콘 혼입 섬유는 아스콘 충진재의 사전 혼입을 통한 섬유의 분산성을 확보한 것이다. 복합 섬유를 혼입한 교량 포장층을 시공함에 있어 발생할 수 있는 제반 상황을 사전에 인지할 수 있도록, Mock Up 포장층에 대한 기본적인 성능 분석을 실시하였다. 분석 결과, 친환경 그리드 보강재와 분산성 섬유를 함유한 포장층에서 강도 및 응력, 처짐 저항성에서 모두 기능성이 향상된 것을 확인할 수 있었다. 그러므로, 섬유 실제 현장 적용시 친환경성 재료 도입과 더불어 안전성 측면에도 효율적인 공법이라고 판단된다.
