Abstract
Description
본 발명은 건설 재료에 관한 것으로서, 상세하게는 개질 아스팔트를 이용한 구스 아스팔트에 관한 것이다.The present invention relates to construction materials, and in particular, to goose asphalt using modified asphalt.
구스 아스팔트(guss asphalt)는 석회, 석분, 천연 아스팔트 분말을 주재료로 하는 특수 아스팔트 포장재를 말하며, 매스틱 아스팔트(mastic asphalt), 아스팔트 꿀레(asphalt coule) 등으로 불리운다.Goose asphalt (guss asphalt) refers to a special asphalt pavement mainly made of lime, stone powder, natural asphalt powder, and is called mastic asphalt, asphalt coules and the like.
이는 위 주재료가 적절한 비율로 배합된 혼합액, 골재, 모래, 석분 등을 고온(170~250℃)에서 혼합한 후 포설하는 방식으로 시공되는데, 구스 아스팔트 포장의 특징은 유동성, 불투수성, 충격 저항성과 내구성 그리고 휨에 대한 추종성(Compatibility)을 바탕으로 강상판의 교통하중에 대한 변형에 저항하도록 하고 있기 때문에, 골재의 맞물림을 하중 전달의 기본 개념으로 하고 있는 일반 아스팔트 혼합물 포장과는 상당히 다른 거동을 보인다.It is constructed by mixing and mixing mixed liquid, aggregate, sand, stone powder, etc. mixed in the appropriate ratio at high temperature (170 ~ 250 ℃), and the characteristics of goose asphalt pavement are fluidity, impermeability, impact resistance and durability. In addition, it is very different from the general asphalt mixture pavement, which uses aggregate engagement as the basic concept of load transfer, because it is resistant to deformation of the steel plate based on its compatibility with bending.
구스 아스팔트 혼합물의 불투수성으로 휨에 대한 적용성이 높기 때문에 일반적으로 강상판 포장 등의 교면포장에 많이 사용된다.Due to the impermeability of the goose asphalt mixture, its applicability to warpage is high, so it is generally used for cross-section paving such as steel plate pavement.
종래의 구스 아스팔트는 시공성의 개선이나 고온시의 내유동성을 위하여, 일반적으로 석유 아스팔트에 천연 아스팔트를 첨가하여 사용하며, 천연 아스팔트의 함량은 아스팔트 함량의 20~30% 정도이다.Conventional goose asphalt is generally used by adding natural asphalt to petroleum asphalt for improving workability or fluid resistance at high temperatures, and the content of natural asphalt is about 20 to 30% of the asphalt content.
천연 아스팔트는 아스팔트의 점도 증가, 내산화성의 향상, 응집체와의 밀착성 및 필링 저항의 개선, 고온 및 장기 조건에서도 접착력의 향상 등의 장점이 있다.Natural asphalt has advantages such as increasing the viscosity of the asphalt, improving the oxidation resistance, improving the adhesion to the aggregates and the peeling resistance, improved adhesion even at high temperature and long-term conditions.
그러나 함유된 미네랄의 함량이 일정하지 않아 구스 아스팔트 혼합물에 대한첨가 시 균일한 배합비율을 유지할 수 없다는 점, 200℃가 넘는 고온에서 구스 아스팔트 시공 시 발생되는 유증기에 의한 냄새 및 연기 배출이 심하다는 점, 구스 아스팔트 혼합물 쿠커에서 별도로 천연 아스팔트를 투입하는 공정이 추가되어야 한다는 점 등의 단점이 있다.However, since the content of minerals is not constant, it is not possible to maintain a uniform mixing ratio when adding to the goose asphalt mixture, and the odor and smoke emission due to the vapor generated during goose asphalt construction at a high temperature of more than 200 ° C are severe. However, there is a disadvantage in that a process of adding natural asphalt separately from the goose asphalt mixture cooker has to be added.
따라서 천연 아스팔트의 혼입 없이 구스 아스팔트를 제조하기 위한 연구가 진행되어 왔다.Therefore, research has been conducted to manufacture goose asphalt without incorporation of natural asphalt.
본 발명은 상기와 같은 문제점을 해결하기 위하여 도출된 것으로서, 천연 아스팔트를 혼입하지 않음에 따라, 균일한 배합비율을 유지할 수 있고, 고온에서의 냄새 및 연기 배출을 저하시킬 수 있으며, 효율적인 공정관리가 가능하면서도, 도로포장의 내구성, 열안정성, 소성변형 저항성, 내후성, 내마모성 등의 특성을 향상시킬 수 있도록 하는 개질 아스팔트를 이용한 구스 아스팔트를 제시하는 것을 그 목적으로 한다.The present invention has been derived to solve the above problems, by not mixing natural asphalt, it is possible to maintain a uniform mixing ratio, to reduce the emission of odors and smoke at high temperatures, and efficient process management It is an object of the present invention to provide a goose asphalt using modified asphalt which can improve the characteristics of road pavement durability, thermal stability, plastic deformation resistance, weather resistance, abrasion resistance and the like.
