Description
본 발명은 아스팔트 혼합물 조성물에 관한 것이다.The present invention relates to asphalt mixture compositions.
아스팔트는 주로 도로포장용으로 널리 사용되고 있는 물질로서 석유정제공정에서 저비점 유분(油分)을 증류하고 남은 잔류물(殘留物)로 얻어지며, 주로 수소 및 탄소로 구성되어 있고, 소량의 질소, 황, 산소가 결합된 화합물로서 흑색 또는 흑갈색을 띄며, 화학적으로 복잡한 구조를 가지고 있다.Asphalt is a material widely used mainly for road paving. It is obtained from the residue left after distilling low-boiling oil in the petroleum refining process. It is mainly composed of hydrogen and carbon, and small amounts of nitrogen, sulfur, and oxygen. It is a compound of which is combined, is black or dark brown in color, and has a chemically complex structure.
일반적으로 아스팔트 콘크리트(아스콘으로도 약칭되고 있음)는 아스팔트와 굵은골재, 잔골재 및 채움재(석회석 분말, 시멘트 등)를 혼합, 가열하는 과정을 거쳐 도로포장이나 주차장 등에 널리 사용되고 있으며, 이러한 아스팔트 포장은 시공 후 5년이 되기 전에 주행트랙을 따라 가끔 소성변형이 생겨서 심각한 주행문제를 발생시키거나, 소성변형 문제가 없다 하더라도 아스팔트는 포장공용기간에 공기 중의 산소에 의해 아스팔트가 서서히 산화되어 유연성을 잃고 딱딱해지면서 노화되며, 아스팔트가 딱딱해지면 공용 중의 차량하중에 의해 쉽게 균열이 발생하며, 균열은 서서히 거북등 균열로 진행되다가 마침내 포장으로서의 기능을 상실하고 포장수명을 종료하게 된다.In general, asphalt concrete (also abbreviated as asphalt) is widely used in road pavements and parking lots, etc. through the process of mixing and heating asphalt, coarse aggregate, fine aggregate, and filler (limestone powder, cement, etc.). Before 5 years have elapsed, plastic deformation occasionally occurs along the driving track, causing serious driving problems, or even if there is no plastic deformation problem, asphalt is gradually oxidized by oxygen in the air during the paving period, losing flexibility and becoming hard. As the asphalt ages, it hardens and easily cracks due to the load of vehicles in use. The cracks gradually progress to turtle-shaped cracks, and eventually lose their function as a pavement and end their lifespan.
이러한 소성변형 내지 노화된 포장은 하부구조를 보호하기 위하여 주로 표층을 절삭하거나 걷어내고 그 위에 덧씌우기 포장을 하는 것으로 유지보수시공을 많이 하여 왔다.In order to protect the substructure of such plastically deformed or aged pavements, maintenance work has been carried out mainly by cutting or removing the surface layer and covering it with pavement.
그러나 이러한 폐아스팔트의 재활용은 각 지역 및 해당 기관의 폐아스팔트의 재활용에 대한 부정적 시각과 여러 가지 제한조건으로 인하여 극히 미진한 실정에 있으며, 신재 아스콘보다 품질이 우수한 고기능 재생 아스팔트 혼합물의 생산이 절실히 요구되고 있다.However, the recycling of waste asphalt is extremely poor due to the negative views and various restrictions on the recycling of waste asphalt by each region and relevant organization. There is an urgent need for the production of high-performance recycled asphalt mixtures with better quality than new asphalt. there is.
본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 안정도와 강도 등의 품질이 향상된 아스팔트 혼합물을 제공하는 것이다.The present invention was devised to solve the above problems, and the purpose of the present invention is to provide an asphalt mixture with improved qualities such as stability and strength.
본 발명의 과제는 이상에서 언급한 과제들로 제한되지 않으며, 언급되지 않은 또 다른 과제들은 아래의 기재로부터 당업자에게 명확하게 이해될 수 있을 것이다.The object of the present invention is not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.
