Abstract
Description
본 발명은 아스팔트 포장용 채움재 조성물에 관한 것으로, 보다 상세하게는 미세한 입자사이즈의 채움재를 사용하므로써 공극충진효과가 우수할 뿐만 아니라 침수팽창율을 낮출 수 있는, 아스팔트 포장용 채움재 조성물에 관한 것이다.The present invention relates to a filler composition for asphalt pavement, and more particularly, to a filler composition for asphalt pavement, which can reduce the submerged expansion rate as well as excellent in void filling effect by using a filler having a fine particle size.
아스팔트 콘크리트용 채움재는 아스팔트 콘크리트용 혼합물 내에서 골재 간의 간극을 충전시켜 주고, 채움재와 바인더인 아스팔트가 결합한 채움재-바인더로서의 작용을 한다.The filler for asphalt concrete fills the gap between the aggregates in the mixture for asphalt concrete, and acts as a filler-binder in which the filler and the binder, asphalt, are combined.
이러한 채움재의 특성 때문에 채움재의 품질은 아스팔트 콘크리트용 혼합물의 물성과 밀접한 관련이 있다.Because of these characteristics of the filler, the quality of the filler is closely related to the properties of the mixture for asphalt concrete.
KS F 3501 아스팔트 포장용 채움재 규격에 의하면 채움재는 석회석분, 포틀랜드 시멘트, 소석회, 플라이애시, 회수더스트, 전기로 제강더스트, 주물더스트, 각종 소각회 및 기타 적당한 광물성 물질의 분말이라고 규정하고 있다.According to the KS F 3501 asphalt pavement fill material specification, the filler material is limestone powder, portland cement, slaked lime, fly ash, recovered dust, electric furnace steelmaking dust, casting dust, various incineration ash and other suitable mineral powders.
일반적으로 산업현장에서는 아스팔트 포장용 채움재로서 석회석분이 주로 사용하고 있으며, 가열 아스팔트혼합물을 제조하는 공장에서는 골재를 가열할 때 발생하는 분진을 집진한 회수 더스트를 석회석분과 혼합하여 사용하고 있다.In general, limestone powder is mainly used as a filling material for asphalt pavement in industrial sites, and in factories that manufacture heated asphalt mixtures, the collected dust collected when heating aggregates is mixed with limestone powder and used.
포틀랜드 시멘트와 소석회는 석회석을 열분해한 후 추가공정을 거쳐 발생되는 물질로서 석회석을 단순 파쇄한 석회석분에 비하여 상당히 고가이기 때문에 산업현장에서는 잘 사용되고 있지 않다.Portland cement and slaked lime are substances that are generated through an additional process after pyrolysis of limestone, and are not used well in industrial fields because they are considerably more expensive than limestone powder obtained by simply crushing limestone.
또한, 플라이애시의 경우 한국전력 화력발전소에서 배출되며 대부분 콘크리트 혼화재료로 활용되고 있으나, 그 밀도가 1.8 내지 2.2g/cm3 정도의 가벼운 물질로서 KS F 3501 아스팔트 포장용 채움재 규격에 의한 품질특성 중 흐름값이 규격에 적합하지 않은 경우가 많아 널리 사용되지 않고 있는 실정이다.In the case of fly ash, it is emitted from the KEPCO thermal power plant and is mostly used as a concrete admixture material, but it is a light material with a density of about 1.8 to 2.2 g/cm 3 , and flows among the quality characteristics according to the KS F 3501 asphalt pavement filler standard In many cases, the value does not conform to the standard, so it is not widely used.

상기 아스팔트 포장용 채움재 조성물은 시멘트를 전혀 사용하지 않고 산업부산물만을 사용하기 때문에 친환경적인 장점이 있지만, 침수팽창율이 높은 단점이 있다. Since the filler composition for asphalt pavement does not use any cement and uses only industrial by-products, it has an environmental-friendly advantage, but has a disadvantage in that the submerged expansion rate is high.
본 발명의 목적은 미세한 입자사이즈의 채움재를 사용하므로써 공극충진효과가 우수할 뿐만 아니라 침수팽창율을 낮출 수 있는, 아스팔트 포장용 채움재 조성물을 제공하는 것이다.An object of the present invention is to provide a filler composition for asphalt pavement, which is excellent in void filling effect as well as can lower the submerged expansion rate by using a filler having a fine particle size.

The mechanism of the pothole is caused by the penetration of moisture into the asphalt mixture, and the adhesive strength between the asphalt binder and the aggregate is weakened by the penetrating moisture, resulting in breakage. Therefore, potholes on asphalt pavement mainly occur during the rainy season. These potholes not only reduce the service life of the road due to pavement damage, but also have a higher potential for traffic accidents than other pavement damages. Because potholes occur with rainfall, it can increase the amount of traffic accidents in adverse weather conditions such as rain or snow.

본 발명의 아스팔트 포장용 채움재 조성물은,The filler composition for asphalt pavement of the present invention,
분진, 알루미늄파우더 및 석고를 혼합한 혼합물 100중량부에 대하여 야간 시인성 향상제 1~5중량부를 추가적으로 포함할 수 있다. 1 to 5 parts by weight of a night visibility enhancer may be additionally included with respect to 100 parts by weight of a mixture of dust, aluminum powder, and gypsum.
상기 야간 시인성 향상제는 유리 비드 40~50중량부, 세라믹 비드 30~40중량부, 점도조절제 5~10중량부, 탄산칼슘 5~10중량% 및 돌로마이트 1~5중량%를 포함한다. The night visibility enhancer includes 40-50 parts by weight of glass beads, 30-40 parts by weight of ceramic beads, 5-10 parts by weight of a viscosity modifier, 5-10% by weight of calcium carbonate, and 1-5% by weight of dolomite.
상기 유리 비드는 미끄럼 방지 기능을 부여할 뿐만 아니라, 자동차의 전조등에 의하여 빛이 운전자로 되돌아오게 함으로써(재귀반사성) 야간에 시인성을 갖는 역할을 수행한다.The glass bead not only imparts an anti-slip function, but also serves to have visibility at night by allowing light to return to the driver by the headlamp of the vehicle (retroreflective properties).
상기 유리 비드는 굴절률이 1.5~1.6이고, 평균입경이 1,300~1,400㎛인 것이 바람직하며, 유리 비드의 굴절률이 1.5 미만이면 입사된 광선의 초점이 유리 비드 밖에서 형성되어 재귀반사도가 매우 낮게 되므로 야간에 시인성을 확보하기 어렵고, 굴절률이 1.6을 초과하면 유리 비드가 고가인 탓에 경제성이 떨어진다. 유리 비드의 직경이 1,300㎛ 미만이면 노출되기 어렵고, 1,400㎛를 초과하면 균일하게 분산되지 않는 단점이 있다.The glass bead has a refractive index of 1.5 to 1.6 and an average particle diameter of 1,300 to 1,400 μm. It is difficult to secure visibility, and when the refractive index exceeds 1.6, the economical efficiency is lowered because the glass beads are expensive. If the diameter of the glass beads is less than 1,300㎛, it is difficult to be exposed, and if it exceeds 1,400㎛, there is a disadvantage in that it is not uniformly dispersed.
특히, 상기 유리 비드로서 그 표면이 투명한 실란계 화합물 또는 실리콘 오일로 코팅된 것을 사용하면, 초점을 유리 비드 내벽쪽으로 이동시킬 수 있어 재귀반사도 향상에 기여할 수 있다.In particular, when a glass bead whose surface is coated with a transparent silane-based compound or silicone oil is used, the focus can be shifted toward the inner wall of the glass bead, thereby contributing to the improvement of retroreflectivity.
상기 세라믹 비드는 유리 비드보다 굴절률 및 평균입경이 큰 것을 사용함으로써 쉽게 노출시켜 야간의 우천시에도 시인성이 현저히 증가할 수 있으며, 이러한 세라믹 비드로서는 세라믹 비드의 총중량을 기준으로 적어도 10 중량%의 란타니아(La2O3)를 함유하는 것이 높은 굴절률을 유지할 수 있어 바람직하다. 상기 세라믹 비드는 굴절률이 2.2~2.4이고, 평균입경이 1,600~1,700㎛인 것이 바람직하다. The ceramic beads can be easily exposed by using those having a larger refractive index and average particle diameter than glass beads, so that visibility can be significantly increased even in rain at night. La 2 O 3 ) is preferable because it can maintain a high refractive index. The ceramic beads preferably have a refractive index of 2.2 to 2.4 and an average particle diameter of 1,600 to 1,700 μm.
상기 점도조절제는 점도를 조절함으로써 유리 비드와 세라믹 비드의 결합성 및 혼화성을 향상시키고, 유리 비드의 침전 및 탈리를 방지하여 휘도를 높게 하는 역할을 수행하는 것으로, 아크릴계 그라프트 공중합체를 사용한다. 상기 아크릴계 그라프트 공중합체의 예로서는 부타디엔 고무, 아크릴 고무 또는 스티렌-부타디엔 고무에 메틸메타크릴레이트와 스티렌 및 아크릴로니트릴의 단량체를 혼합물의 형태로 그라프트 공중합한 것이 있고, 메틸메타크릴레이트, 스티렌 및 아크릴로니트릴의 그라프트 공중합체가 더욱 바람직하다.The viscosity modifier improves the bondability and miscibility of glass beads and ceramic beads by controlling the viscosity, and serves to increase luminance by preventing precipitation and desorption of glass beads, and an acrylic graft copolymer is used. . Examples of the acrylic graft copolymer include those obtained by graft copolymerization of butadiene rubber, acrylic rubber or styrene-butadiene rubber with monomers of methyl methacrylate, styrene and acrylonitrile in the form of a mixture, methyl methacrylate, styrene and A graft copolymer of acrylonitrile is more preferred.
상기 탄산칼슘은 화학적으로 안정하고, 폐기시 환경에 미치는 영향과 독성이 없으며, 보강재의 역할을 하여 굽힘응력과 압축응력에 탄력적으로 대응하여 충격을 완화시키는 역할을 한다.The calcium carbonate is chemically stable, has no environmental impact and toxicity when disposed of, and acts as a reinforcing material to respond elastically to bending stress and compressive stress to mitigate impact.
상기 돌로마이트는 수지와 배합성이 매우 우수한 Ca와 Mg의 복탄산염으로, 일반 모래보다 수지와의 혼화성이 우수하다. 서로 다른 입자크기를 갖는 돌로마이트를 혼합사용하여, 중간입경과 작은입경의 돌로마이트가 공극을 채워줌으로써 아스팔트의 안정화를 기할 수 있고, 아스팔트의 조면화를 효율 좋게 유지할 수 있다.The dolomite is a bicarbonate of Ca and Mg having very good compatibility with the resin, and has better compatibility with the resin than general sand. By mixing and using dolomite having different particle sizes, dolomite of medium particle size and small particle size fills the voids, thereby stabilizing the asphalt and maintaining the roughening of the asphalt efficiently.
