Abstract

In this study, in order to improve the mechanical properties and durability of asphalt mixtures, a modifier (CSM, Cationized Silicate Modifier) was applied to asphalt to derive optimal mixing ratio conditions. Design of asphalt mixture using modified asphalt binder was conducted, and moisture resistance and dynamic stability were evaluated for optimal mixing conditions. The evaluation results showed that it exceeded the standards stipulated in the relevant guidelines, and as a result of conducting a water permeability test on the optimal mixing condition, it was confirmed that impermeable performance was secured. As a result of examining the noise reduction performance through field test, a noise reduction performance of about 10 dB was secured compared to before paving. It will be necessary to secure reliability through continuous noise generation evaluation in the future.

본 연구에서는 아스팔트 혼합물의 역학적 특성 및 내구성을 향상시키기 위해 양이온 처리된 실리케이트 섬유를 활용한 개질재(CSM, Cationized Silicate Modifier)를 아스팔트에 적용하여 최적 혼입률 조건을 도출하였다. 개질 아스팔트 바인더를 활용한 아스팔트 혼합물의 배합설계를 실시하였으며, 최적 배합 조건을 대상으로 수분저항성 및 동적안정도의 내구성을 평가하였다. 평가결과 관련 지침에서 규정하고 있는 기준을 상회하는 것으로 나타났으며, 최적 배합비를 대상으로 투수시험을 실시한 결과 비배수성능을 확보하는 것으로 확인되었다. 현장 시험시공을 통해 소음저감 성능을 검토한 결과 포장 전 대비 약 10 dB의 소음 저감 성능을 확보하였으며, 추후 지속적인 소음 발생도 평가를 통해 신뢰성을 확보할 필요가 있을 것으로 판단된다.
