Abstract

The efforts to reduce carbon emission have been made in many aspects and in road, the study to develop the construction method which will replace asphalt and cement is also underway. But given the low cost and high performance offered by cement, among many solidification agents, it's difficult to seek the competent alternative. Polymeric material has been used in various ways for its advantages including lightweight and easy process for complex function and generates less carbon emission, and thus it would possibly be efficient if it replaces soil pavement using cement. This study, using three different types of organic polymeric solidification agents with different solidification principle, is intended to identify the difference in strength depending on curing method, natural dry or oven dry. Applicability of organic polymeric solidification agents to walkway and bike lane was investigated and as a result of unconfined strength test, all of them satisfied the minimum strength requirements of bike lane. Furthermore, strength characteristics of soil pavement depending on variation of water content was evaluated to identify the relationship, thereby appropriate curing method using organic polymeric solidification agent is proposed.

탄소배출을 줄이기 위해 각 분야에서 연구가 활발히 진행되고 있고, 도로분야에서도 아스팔트 및 시멘트를 대체하는 공법을 개발하기 위하여 노력하고 있다. 그러나 고화제 중에서 시멘트는 가격이 저렴하고 성능이 우수하여 이를 대체하기에 어려운 실정이다. 고분자 재료는 가벼우면서도 복합기능을 추가할 수 있도록 가공이 쉬워서 여러 가지 용도로 사용되고 있으며, 제조공정에서 탄소배출이 적어서, 시멘트를 이용한 흙 포장을 대체한다면 그 효과가 크다. 본 연구에서는 고화 원리가 다른 3종류의 유기계 폴리머 고화제를 사용하여 공기 중 양생과 건조로에 의한 양생을 적용하여 양생방법에 따른 강도의 차이점을 파악하였다. 유기계 폴리머 고화제만을 적용하여 산책로 및 자전거도로의 포장에 사용 가능한지를 파악하여, 3가지 종류의 고화제를 적용한 일축압축강도시험에서 모두가 자전거 도로의 최소 소요강도를 만족하는 것으로 나타났다. 그리고 공시체의 함수비 변화에 따르는 흙 포장체의 강도 특성을 평가하여 상관관계를 제시하고 유기계 폴리머 고화제를 이용한 경우의 적절한 양생방법을 제시하였다.
