초록

연구목적: 본 연구에서는 친환경 소재인 알톱밥과 EPDM칩을 사용하여 친환경 포장재의 개발을 목적으로 한다. 연구방법: 친환경 재료로 환경적으로 문제가 없고, EPDM칩을 사용함으로써 보행감을 높이며, 알톱밥에 소금물 혼합 우드스테인과 우레탄바인더를 혼합하여 내구성을 향상시킨다. 연구결과: 배합설계 시험을 통하여 최적 배합비를 산출하였고, 배합비를 바탕으로 세립의 알톱밥과 EPDM칩을 사용하여 보도의 표층재, 단입도의 알톱밥만을 사용하여 투수성과 반탄력을 갖춘 보도의 기층재 및 자전거도로의 표층재로 구성하였고 시험시공을 통해 적용공법을 제시하였다. 결론: 본 연구를 통해 기존의 탄성포장재와 달리 휨강도를 제시하고 우수한 투수계수를 나타냄으로 보도포장재로서 경제적인 시공이 바로 가능할 것으로 판단된다.

Purpose: This study aims to develop eco - friendly paving materials using Sawdust and EPDM chips. Method: Materials are eco-friendly materials and have no environmental problems. By using EPDM chip, the walking feeling can be increased. Results: In this study, the optimum mixing ratio was calculated through mixing design test. Based on the blending ratio, the surface layer of the sidewalk is made of fine sawdust and EPDM chips. We used only sawdust of grain - 107 -size to make the base layer of the sidewalks and the surface layer of the bicycle road with the permeability and the anti - resilience, and suggested the application method through the test construction. Conclusion: This study the expected that the recent efforts of the government to reduce the elastic paving material, which is the environmentally harmful problem with the complete eco-friendly paving material, are expected to revive.
