Description

상온 재생 아스콘 제조용 첨가제의 제조방법 {Producing method for Additive for regenerated Ascon at room temperature}Producing method for Additive for regenerated Ascon at room temperature}

본 발명은 상온 재생 아스콘 제조용 첨가제의 제조방법에 관한 것으로서, 보다 상세하게는 도로건설을 위한 현장타설시 상온 재생 아스콘의 양생시간이 단축되고, 재료간 결합력이 증진되며, 백태현상 및 수화반응이 제거되도록 하는 첨가제의 제조방법에 관한 것이다.
The present invention relates to a method for preparing additives for the production of room temperature regenerated ascon, and more particularly, the curing time of the room temperature regenerated ascon during site casting for road construction is shortened, the bonding force between materials is enhanced, and the white phenomena and the hydration reaction are removed. It relates to a method for producing an additive to be.

도로포장에 사용되는 아스팔트 콘크리트인 아스콘은 우리나라 도로포장의 90%이상을 차지하고 있으며, 폐기되는 아스콘도 연간 800만톤에 이르고 있는 실정이다. 폐기되는 아스콘의 재이용은 자원 재활용과 환경보호에 유용한 것으로서, 천연골재의 부존자원 절약, 연간 20% 이상 급증하는 건설폐기물의 순환자원화 측면에서 바람직하며, 이를 위해 재생 아스콘을 활용하기 위한 기술개발이 이루어지고 있으며, 상온에서 포장시공을 위해 첨가되는 첨가제의 종류도 다양해지고 있다.Ascon, the asphalt concrete used for road paving, accounts for more than 90% of Korea's road paving, and ascon discarded reaches 8 million tons per year. The reuse of discarded ascon is useful for resource recycling and environmental protection. It is desirable in terms of saving natural resources of natural aggregates and recycling resources of construction waste, which is increasing by more than 20% annually. In addition, the variety of additives added for packaging at room temperature is also increasing.

종래의 첨가제는 기존의 구제아스팔트의 물성인 연화점침입도를 회복시켜 신제아스팔트의 사용량을 줄이고 경제성을 높이며 제품의 품질을 높이고자 하고 있으나, 실제적으로는 구제아스팔트의 물성변화는 매우 미미한 형편으로써 아스콘 성능평가의 주요인자인 안정도값 및 흐름값에 있어서는 개선이 이루어지지 않은 상태에 있다.Conventional additives are intended to restore the softening point penetration, which is the property of conventional asphalt, to reduce the amount of new asphalt used, increase the economics, and improve the quality of the product. There is no improvement in stability value and flow value, which are the main factors of evaluation.

However, the room temperature reclaimed asphalt concrete currently distributed in Korea is recognized as concrete, not asphalt concrete, due to excessive use of cement and water. In addition, most of the current room temperature regenerated ascon is used as a substrate, and there is a problem in that the adhesive strength is lowered due to different physical properties from the heated ascon on the surface layer, and freezing and thawing occurs with water, causing problems such as road damage. .

국내등록특허공보 제10-0982350호 (등록일자: 2010.09.08.) 는 상온 재생 아스콘에 활용되는 첨가제로 에멀젼계 아로마틱 기유를 이용하여 구제 아스팔트 및 유화 아스팔트의 침입도 성능 회복 등의 물성변화를 이루는 것으로 하고 있으나, 현장타설시 중요한 재료간 결합력 증대, 잔입자 분리현상 감소 및 아스콘의 양생속도 개선 등은 이루어지지 않고 있는 형편이다.

상기 표2에서 보는 바와 같이, 신재 아스팔트 함량을 감소한 상태에서 다른 혼합물이 증가되는 경우에도 상온 재생 아스콘혼합물의 성능에 중요한 안정도와 흐름값이 기준치를 상회하거나 기준치 범위 내에 존재함으로써 본 발명의 첨가제를 상온 재생 아스콘에 첨가하여 사용할 때 큰 효과를 얻을 수 있음을 알 수 있다.
As shown in Table 2 above, the additives of the present invention are at room temperature because stability and flow values that are important for the performance of the room temperature regenerated ascon mixture exceed the reference value or are within the reference value range even when other mixtures are increased while the new asphalt content is decreased. It can be seen that a great effect can be obtained when used in addition to recycled asphalt.

이상에서 본 발명의 바람직한 실시 예를 설명하였으나, 본 발명의 권리범위는 이에 한정되지 아니하며 본 발명의 실시 예와 실질적으로 균등한 범위에 있는 것까지 본 발명의 권리범위가 미치는 것으로 이해되어야 하며, 본 발명의 정신을 벗어나지 않는 범위 내에서 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 다양한 변형 실시가 가능하다.Although the preferred embodiment of the present invention has been described above, the scope of the present invention is not limited thereto, and it should be understood that the scope of the present invention extends to the range that is substantially equivalent to the embodiment of the present invention. Various modifications can be made by those skilled in the art without departing from the spirit of the invention.
