Abstract

The method to replace asphalt and cement is needed to reduce the carbon emission on road. Polymeric material which is light and easy to handle while having complex function with less carbon emission would be highly effective when it replaced soil pavement containing cement. This study is intended to identify the usability of soil pavement containing organic solidification agent only through the field test. Pavement on bike trail still satisfied required bearing capacity coefficient in 3 months. Pavement after passing 1.6 bil units of bike through pavement acceleration test that simulated a long-term serviceability during a short-time still remained unaffected, demonstrating a long-term serviceability of soil pavement.

도로분야에서 탄소배출을 줄이기 위해서는 아스팔트 및 시멘트를 대체하는 공법이 필요하다. 고분자 재료는 가벼우면서 가공이 쉬워 여러 가지 복합기능을 가지는 재료로, 제조공정에서 탄소배출이 적어 시멘트 등이 사용되는 흙포장을 대체한다면 그 효과가 클 수 있다. 본 연구에서는 유기계 고화제만 적용한 흙포장의 현장시험을 통한 사용성을 파악하였다. 실 규모의 자전거도로로 조성된 포장체는 3개월 노출 후에도 노상의 지지력계수 기준을 만족하는 것으로 나타났다. 포장 구조체의 장기 공용성을 단기간에 모사하는 포장가속시험으로 16억대의 자전거가 통과한 후 포장체의 상태에는 큰 변화가 없는 것으로 타나나 흙포장으로서 장기 공용성을 만족하는 것으로 평가되었다.
