Abstract

This research explores the potential of methyl methacrylate(MMA) as a material for road repair applications. It specifically examines two MMA formulations, referred to as type A and type B, in relation to their performance on concrete substrates. The evaluation criteria included drying time, tensile bond strength, and resistance to alkali. The condition of the substrate surface was varied across three curing environments: constant temperature and humidity(R), immersion in water(W), and immersion in water with chloride ions(N). The findings indicate that type B MMA exhibits a quicker drying time and superior resistance to alkali compared to type A. While type A demonstrated greater tensile bond strength, it failed to maintain adhesion with the concrete base. Based on the parameters tested in this study, type B MMA emerges as the more favorable option for road repair contexts. Nonetheless, the study underscores the necessity for additional testing on asphalt substrates to fully assess the material's durability and applicability for long-term road maintenance.

본 연구에서는 도로 보수재로서 메틸 메타크릴레이트(MMA)의 활용 적합성을 평가하였다. A type과 B type의 2가지 MMA를 콘크리트에 적용하여 건조시간, 인장 접착 강도, 내알칼리 시험을 진행하였다. 항온항습(R), 수중(W), 수중+염화이온(N)의 3가지 조건으로 양생하여 모체의 표면 상태를 설정하였다. 시험 결과, B type MMA가 A type 보다 빠른 건조시간과 우수한 내알칼리성을 나타냈다. 인장 접착 강도는 A type이 더 높게 나타났지만, 콘크리트 모체와 함께 탈락되었다. 본 연구 범위에서는 B type이 도로 보수재로 사용하기 적합하다고 판단된다. 그러나 내구성을 고려하여 아스팔트 모체에서의 추가 실험을 진행할 필요가 있다.
