Description

아스콘 개질제Ascon Modifier
본 발명은 아스콘 개질제에 관한 것으로서, 더욱 상세하게는 아스팔트의 내구성을 향상시키기 위해 첨가되어지는 개질제 조성물에 관한 것이다.FIELD OF THE INVENTION The present invention relates to ascon modifiers, and more particularly to modifier compositions that are added to improve the durability of asphalt.
일반적으로, 아스콘은 아스팔트와 굵은 골재, 잔골재 및 채움재 (석회석 분말, 시멘트 등)를 가열혼합한 것으로 도로포장이나 주차장 등에 널리 사용되고 있다.In general, ascon is a mixture of asphalt and coarse aggregates, fine aggregates and fillers (limestone powder, cement, etc.), and is widely used in road paving and parking lots.
이러한 아스콘 포장은 시공 후 5년이 되기 전에 주행트랙을 따라 가끔 소성변형이 생겨서 심각한 주행문제를 발생시키거나, 소성변형 문제는 없다 하더라도 시간의 흐름과 함께 포장 재료가 점차 노화되어 결국에는 심한 균열을 발생시킨다. 문제된 포장은 하부구조를 보호하기 위하여 주로 표층을 절삭하거나 걷어내고 그 위에 덧씌우기 포장을 하는 유지보수시공을 많이 한다.Such ascon pavement sometimes causes severe driving problems along the running track before the 5 years of construction, causing serious driving problems, and even if there is no plastic deformation problem, the packaging material gradually ages and eventually causes severe cracking. Generate. The pavement in question involves a lot of maintenance work mainly to cut or roll off the surface layer and overlay the overlaid pavement to protect the infrastructure.
그러나, 최근 도로포장의 해체 및 유지보수의 증가로 인하여 폐아스콘의 발생량(연간 약 600만톤)이 급격히 증가하고 있어 심각한 환경오염 및 자원낭비의 문제를 야기하고 있는 실정이다. 따라서 현재 국가차원에서 대량 으로 발생되고 있는 건설폐기물인 폐아스콘의 자원화를 추진하고 있으며, 폐아스콘의 불법 매립으로 인한 환경오염의 피해를 방지하기 위해 폐아스콘을 지정부산물로 선정하고 재활용률을 선진국 수준으로 끌어올리기 위한 노력을 계속해 가고 있는 중이다. 그러나 이러한 폐아스콘의 재활용은 각 지역 및 해당 기관의 폐아스콘의 재 활용에 대한 부정적 시각 및 여러 가지 제한 조건으로 인하여 극히 미진한 실정으로 신재 아스콘보다 품질이 우수한 고기능 재생 아스콘 혼합물의 생산이 절실히 요구되고 있다.However, due to the recent increase in the dismantling and maintenance of road pavement, the generation of waste ascon (approximately 6 million tons per year) is rapidly increasing, causing serious environmental pollution and resource waste. Therefore, we are promoting the recycling of waste ascon, which is a large amount of construction waste generated at the national level.In order to prevent damage to the environment caused by illegal landfilling of waste ascon, waste ascon is designated as a designated by-product and the recycling rate is reduced to the level of developed countries. We are continuing our efforts to raise it. However, the recycling of waste ascon is extremely low due to the negative viewpoints and various limitations on the reuse of waste ascon in each region and the relevant institutions, and the production of high-performance recycled ascon mixtures with higher quality than new ascons is urgently required. .
종래 폐아스콘을 재활용한 재생 아스콘의 제조방법은 주로 신재 아스팔트 및 오일계 재생첨가제만을 폐아스콘에 혼입하여 폐아스콘에 포함되어 있는 구재 아스팔트의 침입도, 신도, 연화점 등과 같은 물리적 특성을 신재 아스팔트 수준으로 회복시키고, 신재 골재를 사용하여 입도를 시방규정에 적합하게 조정하는 수준에 그쳤다. 이 때문에 기존의 재생 아스콘 물성은 항상 신재 아스콘과 비슷하거나 그 보다 못한 상태에 머물 수밖에 없었으며 재생 아스콘에 대한 평가도 열악하였다. 아스팔트는 포장공용기간에 공기 중의 산소에 의해 아스팔트가 서서히 산화되어 유연성을 잃고 딱딱해지며 이 과정을 아스팔트포장이 노화된다고 한다. 아스팔트가 딱딱해지면 공용 중의 차량하중에 의해 쉽게 균열이 발생하며 이 균열은 서서히 거북등 균열로 진행되다가 마침내 포장으로서의 기능을 상실하고 포장수명을 종료하게 된다. 종래에는 이렇게 딱딱해진 아스팔트에 유연성을 부여하기 위하여 오일계 재생첨가제를 투입하고 신규골재와 신규아스팔트를 사용하여 신재 아스팔트 수준으로 물성의 복원을 시도하여 왔지만 충분한 유연성 확보에는 의문의 여지가 크다.The method of manufacturing recycled ascon recycled waste ascon is mainly by mixing only new asphalt and oil-based regeneration additives into waste ascon to improve physical properties such as penetration, elongation, softening point of old asphalt contained in waste ascon. In addition, the new aggregates were used to adjust the particle size to fit the specification. For this reason, the existing properties of recycled ascon have always remained similar to or less than that of new ascon, and the evaluation of recycled ascon was also poor. Asphalt is gradually oxidized by oxygen in the air during the paving period and loses its flexibility and hardening. As the asphalt hardens, the cracks easily occur due to the load of the vehicle in public, and the cracks gradually progress to cracks in turtles, and finally lose their function as pavement and end pavement life. Conventionally, in order to give flexibility to such hardened asphalt, oil-based regeneration additives have been added, and new aggregates and new asphalts have been used to attempt to restore physical properties to new asphalt levels, but there is much doubt about securing sufficient flexibility.
이러한 시도를 지양하고, 탄성을 지닌 고분자를 폐아스콘에 첨가하여 포장에 유연성을 부여하여 각종 균열에 대한 저항성을 높이며, 동시에 고점도 고분자를 첨가하여 소성변형 저항성도 향상시키고자 함이 본 발명의 주요 기술적 개념이다. 공지특허에도 일부 이러한 문제점을 개선하여 우수한 성능을 확보하고자 고분자 개질제를 첨가하는 경우가 발견된다.The main technical aspect of the present invention is to avoid such an attempt and to add elastic polymer to the waste ascon to give flexibility to the packaging to increase resistance to various cracks, and to improve the plastic deformation resistance by adding high viscosity polymer. Concept. In the known patents, it is also found that a polymer modifier is added to improve some of these problems to ensure excellent performance.
그러나, 종래 사용되는 아스콘 개질제는 고온영역에서 강성(Stiffness)물성이 증가하여 아스팔트 포장의 소성변형에 효과적으로 저항할 수 있는 긍정적인 아스팔트 개질재라고 평가될 수 있으나, 저온 영역에서의 아스팔트 강도의 증가는 동절기에 포장재의 강성을 더욱 증가시켜 포장재의 균열을 발생시킬 수 있는 문제점이 발생 되었다.However, conventionally used ascon modifiers can be evaluated as positive asphalt modifiers that can effectively resist plastic deformation of asphalt pavement due to increased stiffness in high temperature region. In winter, there was a problem that can increase the rigidity of the packaging material to cause cracking of the packaging material.
본 발명은 상기한 종래 기술에서의 문제점을 개선하기 위해 제안된 것으로서, 고온영역 뿐만 아니라 저온영역에서도 아스팔트 포장의 소성변형에 효과적으로 대응할 수 있도록 하여 포장재의 균열발생을 최소화 할 수 있도록 하는데 목적이 있다.The present invention has been proposed to improve the above problems in the prior art, and has an object to effectively cope with plastic deformation of asphalt pavement in a low temperature region as well as a high temperature region to minimize the occurrence of cracks in the pavement.
상기 목적을 이루기 위한 본 발명은, 분자량을 각기 달리하는 3종류의 SBS(Styrene Butadiene Styrene) 40~80중량%와, SB(Styrene Butadiene) 라텍스 15~55중량%, 그리고 수용성 규산염(Na2Sio3) 5~10중량%를 포함하는 조성을 이룸을 특징으로 한다.The present invention for achieving the above object is, 40 to 80% by weight of three kinds of SB (Styrene Butadiene Styrene), 15 to 55% by weight of SB (Styrene Butadiene) latex, and water-soluble silicate (Na 2 Sio 3) A) a composition comprising 5 to 10% by weight.
상기에서 SBS는 분자량 50,000~100,000이 1~15중량%, 분자량 150,000~200,000이 3~32중량% 그리고 분자량 300,000~350,000이 10~43중량%로 혼합되어짐이 바람직하다.In the SBS, the molecular weight of 50,000 to 100,000 is preferably 1 to 15% by weight, the molecular weight of 150,000 to 200,000 is 3 to 32% by weight, and the molecular weight of 300,000 to 350,000 is preferably mixed at 10 to 43% by weight.

그리고, 상기에서 본 발명의 특정한 실시 예가 설명 및 도시되었지만 본 발명의 개질제 조성물이 당업자에 의해 다양하게 변형되어 실시될 수 있음은 자명한 일이다.In addition, although specific embodiments of the present invention have been described and illustrated above, it is obvious that the modifier composition of the present invention may be variously modified and implemented by those skilled in the art.
그러나, 이와 같은 변형된 실시예들은 본 발명의 기술적 사상이나 범위로부터 개별적으로 이해되어져서는 안되며, 이와 같은 변형된 실시 예들은 본 발명의 첨부된 특허청구범위 내에 포함된다 해야 할 것이다.However, such modified embodiments should not be understood individually from the spirit or scope of the present invention, such modified embodiments will be included within the appended claims of the present invention.
이러한 본 발명의 아스팔트 개질재는, 고온에서는 강도가 강해지고, 저온 상황에서는 균열에 견딜 수 있게 되어 도로 포장에 적용될 경우, 내구 성능이 향상되고, 하중에 대한 대응력이 향상되어 결국 포장 도로의 수명을 연장시킴으로써 아스팔트 포장 및 유지 보수등에 소요되는 비용을 획기적으로 줄일 수 있게된다.Asphalt modifier of the present invention, the strength is high at high temperatures, and can withstand cracks at low temperatures, when applied to the pavement, the durability performance is improved, the ability to respond to the load is improved to eventually extend the life of the pavement By doing so, it is possible to drastically reduce the cost of asphalt pavement and maintenance.
