상술한 목적, 특징들 및 장점은 첨부된 도면 및 아래의 시험 결과와 관련한 다음의 상세한 설명을 통하여 보다 분명해 질 것이다. The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings and the test results below.

이하, 시험 결과 및 첨부된 도면을 참조하여 본 발명에 따른 바람직한 일실시예를 상세히 설명한다.Hereinafter, with reference to the test results and the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

본 발명에 따른 폐타이어 고무분말과 폴리에틸렌 왁스를 첨가한 개질아스팔트 바인더 조성물 및 그의 제조방법은 고온에서의 소성변형 저항성, 저온에서의 균열저항성을 향상시키면서, 또한 시공온도에서 아스팔트 혼합물의 워커빌리티를 개선할 수 있도록 개선한 것이다. The modified asphalt binder composition comprising the waste tire rubber powder and the polyethylene wax according to the present invention and its manufacturing method can improve the plastic deformation resistance at high temperature and the crack resistance at low temperature, and also improve the workability of the asphalt mixture at the construction temperature. It would be improved.

본 발명은 도1에 도시한 바와 같이, 베이스 아스팔트(Base Asphalt) 82 ∼ 89중량%에, 폐타이어 고무분말(120mesh) 10~15 중량%, 폴리에틸렌 왁스(Polyethylene Wax; 이하, 'PE Wax'라 칭함) 1~3 중량%를 첨가하여 균일상으로 분산하여 개질 아스팔트 바인더를 제조한다.As shown in Figure 1, the base asphalt (Base Asphalt) 82 to 89% by weight, waste tire rubber powder (120 mesh) 10-15% by weight, polyethylene wax (hereinafter referred to as "PE Wax") 1 to 3% by weight is added and dispersed in a uniform phase to prepare a modified asphalt binder.

또한, 상기한 바와 같은 조성물을 갖는 본 발명의 제조방법을 살펴보면 다음과 같다.In addition, looking at the manufacturing method of the present invention having a composition as described above are as follows.

먼저, 150±2℃에서 가열된 베이스 아스팔트(Base Asphalt) 82 ∼ 89중량%에 PE(Polyethylene) Wax 1~3중량%를 교반기에 투입하여 130~140℃에서 1차 혼합을 실시한다. 그리고, 1차혼합을 완료한 후 폐타이어 고무분말(120mesh) 10~15중량%를 교반기에 투입하여 150~160℃에서 2차혼합을 실시하여 개질아스팔트 바인더를 제조한다.First, 1 to 3% by weight of PE (Polyethylene) Wax is added to the stirrer at 82 to 89% by weight of the base asphalt heated at 150 ± 2 ° C., followed by primary mixing at 130 to 140 ° C. After completion of the first mixing, 10-15% by weight of the waste tire rubber powder (120 mesh) was added to the stirrer to carry out the second mixing at 150-160 ° C. to prepare a modified asphalt binder.

상기한 조성으로 제조되는 본 발명은 PG 등급 82-22를 만족하여 기존 개질아스팔트 바인더와 동등한 고온 저온특성을 나타내며, 시공시 아스팔트 바인더의 워커빌리티를 확인할 수 있는 135℃ 회전점도값은 기존 개질아스팔트 바인더에 비해 절반 이상 낮추어 워커빌리티가 크게 개선된 특징을 나타낸다. The present invention manufactured with the above composition exhibits high temperature and low temperature properties equivalent to existing modified asphalt binders satisfying PG grade 82-22, and the 135 ° C rotational viscosity value that can confirm the workability of the asphalt binder during construction is applied to the existing modified asphalt binders. It is more than half lower than that, which shows a significantly improved workability.

상기 폐타이어 고무분말(120mesh)은 저온에서의 균열저항성을 강화시키며 고온에서의 내유동성을 일부 강화시키는 역할을 하지만 폐타이어 고무분말(120mesh)만을 첨가시 내유동성을 크게 개선시키지 못하며, 폐타이어 고무분말(120mesh)과 PE(Polyethylene) Wax의 조합을 통해 고온에서의 내유동성을 크게 강화시킨다.The waste tire rubber powder (120 mesh) enhances the crack resistance at low temperatures and enhances the flow resistance at a high temperature but does not significantly improve the flow resistance when only the waste tire rubber powder (120 mesh) is added. The combination of powder (120 mesh) and PE (polyethylene) wax greatly enhances the flow resistance at high temperatures.

상기 PE(Polyethylene) Wax는 고온에서 내유동성을 강화시키며 시공온도에서 워커빌리티를 좋게 하는 역할을 하지만 저온에서 딱딱한 특성을 나타내어 균열저항 성을 취약하게 만드는 단점이 있으나, 폐타이어 고무분말(120mesh)과 PE(Polyethylene) Wax의 조합을 통해 PE(Polyethylene) Wax의 단점이 상쇄되어 저온에서의 균열저항성을 강화시킨다. The PE (Polyethylene) Wax strengthens the flow resistance at high temperatures and improves workability at the construction temperature, but has a disadvantage of making the crack resistance vulnerable by exhibiting hard properties at low temperatures, but waste tire rubber powder (120 mesh) and PE Combination of (Polyethylene) Wax offsets the disadvantages of PE (Polyethylene) Wax to enhance crack resistance at low temperatures.

상기 폐타이어의 조성비에서, 폐타이어 고무분말이 10 중량% 미만일 경우에는 고온등급 PG 82를 만족하지 못하며, 15 중량% 이상일 경우에는 135℃ 회전점도 값이 3000cp 이상을 나타내어 워커빌리티 개선효과를 나타내지 못하게 된다. In the composition ratio of the waste tire, when the waste tire rubber powder is less than 10% by weight does not satisfy the high temperature grade PG 82, when more than 15% by weight of 135 ℃ rotational viscosity value is more than 3000cp does not show the workability improvement effect .

상기 PE(Polyethylene) Wax의 조성비에서, PE Wax가 1 중량% 미만일 경우에는 그 양이 너무 소량이여서 Wax의 효과가 나타나지를 않고, 3 중량% 이상일 경우에는 저온에서의 균열저항성이 약화되어 저온등급 PG-22를 만족하지 못하게 된다. In the composition ratio of polyethylene wax, when PE Wax is less than 1% by weight, the amount is too small so that the effect of Wax does not appear. Will not satisfy -22.
