Abstract

This paper presents features of impermeable asphalt pavement material that uses thermoplastic GMA-based polymer(SIS, Stylene Isoprene Stylene) to improve the waterproof performance. Furthermore, as part of this study, the aerodynamic characteristics of the asphalt paving materials, using the newly suggested thermoplastic polymer, are identified through experiments. In the experiment, the aerodynamic characteristics were analyzed by testing on stability, flow values, porosity, dynamic stability, tensile strength ratio and skid resistance in accordance with KS standard and ASTM standard.

본 논문은 GMA(SIS, Stylene Isoprene Stylene) 고분자계 수지를 기반으로 제조된 아스팔트 바인더를 사용하여 플랜트에서 제조하는 혼합물로 방수기능을 갖도록 성능을 개선한 신개념의 불투수성 아스팔트 포장의 연구를 위해 수행하였다. GMA 고분자 수지 기반의 아스팔트는 유연성과 탄성을 바탕으로 중차량의 충격에 의한 영향을 받지 않으며, 우수 시에 포트 홀의 발생과 소성변형 등 여름철 온도 변화에도 안정적이다. 새롭게 제안된 열가소성 폴리머를 사용한 아스팔트 포장재료는 방수기능은 물론 역학적 특성을 검증하기 위해 KS기준과 ASTM기준에 맞게 안정도, 흐름값, 공극률, 동적 안정도, 인장강도비, 미끄럼 저항성 실험을 하여 역학적 특성을 분석 하였다.
