A road pavement composition and road pavement method using the same
A composition for bridge deck paving according to the present invention has a cement binder and an acrylic latex binder as main raw materials and mixes a fiber reinforcement material therein, wherein natural fibers and polylactic acid fibers are used as the fiber reinforcement material, so that the fiber reinforcement material can prevent separation of hydrophilic components and hydrophobic components and improve durability by improving mechanical properties. In addition, by further containing maleic anhydride to the polylactic acid fibers in a certain ratio, it is possible to increase miscibility with hydrophilic components to increase binding properties between compositions, thereby being able to further enhance mechanical properties.
본 발명에 따른 교면 포장용 조성물은 시멘트 결합제와 아크릴 라텍스 결합제를 주원료로 하고, 여기에 섬유보강재를 혼합하되, 상기 섬유보강재로 천연섬유와 폴리유산 섬유가 혼합된 것을 사용함으로써 상기 섬유 보강재가 친수성 성분과 소수성 성분의 분리를 방지하고 기계적 물성을 높여 내구성을 개선할 수 있다. 또한 상기 폴리유산 섬유에 일정 비율로 무수말레산을 더 포함하여 친수성 성분과의 혼화성을 더욱 높여 조성물 간의 결합특성을 증가시키고 이를 통해 기계적 물성을 더욱 높일 수 있다.
