Description

아스콘용 채움재 및 이를 이용한 아스콘 조성물{ASCON FILLER AND ASCON COMPOSITION USING THE SAME}ASCON FILLING MATERIAL AND ASCON COMPOSITION USING THE SAME {ASCON FILLER AND ASCON COMPOSITION USING THE SAME}

본 발명은 건설 분야에 관한 것으로서, 상세하게는, 도로 포장에 사용되는 아스팔트 조성물 및 이에 사용되는 채움재에 관한 것이다.TECHNICAL FIELD The present invention relates to the field of construction, and more particularly, to an asphalt composition used for road pavement and a filler used therein.

아스콘이란 아스팔트 콘크리트(Asphalt Concrete)를 줄인 명칭으로서, 포장용 가열 아스팔트 혼합물(KS F 2349 규격), HMA(hot mix asphalt) 등으로도 일컬어진다.Ascon is short for asphalt concrete and is also referred to as pavement heated asphalt mixture (KS F 2349 standard), HMA (hot mix asphalt) and the like.

일반적인 아스콘은 아스팔트 바인더(asphalt binder), 굵은골재(Aggregate), 잔골재(Sand), 채움재(filler)를 고온에서 혼합하여 제조하며, 도로포장용 재료로서 널리 사용되고 있다.General ascon is prepared by mixing asphalt binder (asphalt binder), coarse aggregate (Aggregate), fine aggregate (Sand), filler (filler) at a high temperature, and is widely used as a road paving material.

이들 중 채움재는 75μm 체의 통과율이 70~100중량% 범위인 미세한 분말의 재료를 말하며, 골재 간의 간극을 채워주고, 입도 분포를 양호하게 하는 역할을 하므로, 아스콘의 Warkability, 안정성, 내마모성, 내구성 등의 증진에 많은 영향을 미친다.Among them, the filling material refers to a material of fine powder having a passage rate of 75 μm sieve in the range of 70 to 100% by weight, and fills the gap between aggregates and serves to improve the particle size distribution. It has a lot of influence on promotion.

종래의 채움재로서 많이 사용되어 오던 것 중 대표적인 것으로 석회 석분, 제강 더스트(dust) 등을 들 수 있다.Representative ones that have been used as a conventional filling material is lime lime powder, steelmaking dust, and the like.

석회 석분은 석회석(CaCO3)을 원재료로 하며, 석회석 제품의 생산 중 발생하는 분진을 포집함으로써 얻어진다.Lime lime powder is made from limestone (CaCO 3 ) and is obtained by collecting dust generated during the production of limestone products.

제강 더스트는 고철, 합금철, 생석회 등을 원재료로 하며, 고철의 전기로 용융 공정 중 발생하는 분진을 포집함으로써 얻어진다.Steelmaking dust is made from scrap iron, ferroalloy, quicklime, and the like as raw materials, and is obtained by collecting dust generated during the melting process of scrap iron.

기존의 산업 폐기물 중 대단히 큰 비중을 차지하는 것 중의 하나가 폐유리라 할 수 있는데, 이는 병유리, 판유리 등 일반 유리 제품의 폐품뿐만 아니라, 최근 부각되고 있는 LCD, PDP 등의 방식에 의한 각종 모니터, 텔레비전의 폐기 과정에서 대량으로 발생한다.One of the most important industrial wastes is waste glass, which is not only a waste product of general glass products such as bottle glass and plate glass, but also various types of monitors and televisions using LCD, PDP, etc. Occurs in large quantities during the disposal process.

폐유리를 그대로 매립하는 경우 심각한 공해의 원인이 되므로, 이를 반드시 분쇄하여 폐기하도록 규정되어 있으며, 그 분쇄 공정에서 조분, 미분이 발생하는데, 조분은 인조 대리석, 유리 블록 등의 원료로 사용되고, 미분은 유리 타일, 연마제 등의 원료로 사용된다.When the waste glass is buried as it causes serious pollution, it is prescribed to be crushed and disposed of. In the crushing process, coarse powder and fine powder are generated. The coarse powder is used as a raw material of artificial marble, glass block, etc. It is used as a raw material for glass tiles and abrasives.

그러나, 유리 관련 산업의 급속한 발전과 함께 미분 발생량도 엄청나게 증가하고 있으므로, 위와 같은 방식의 재활용에는 이미 한계에 이르렀으며, 유리 관련 제조업체는 어쩔 수 없이 이를 폐기하기 위하여 엄청난 비용을 지출하고 있는 실정이다.However, with the rapid development of the glass-related industry, the amount of fines generated has increased enormously, and the recycling of the above method has already reached its limit, and glass-related manufacturers are inevitably spending huge costs to dispose of it.

본 발명은 이와 같이 폐유리의 분쇄 공정에서 발생하는 폐유리 분말을 아스콘용 채움재로 활용토록 함으로써, 종래의 폐유리 폐기 비용을 절감할 수 있도록 하는 한편, 공해의 유발원인을 감소시킴을 그 근본취지로 하는 것이다.The present invention utilizes the waste glass powder generated in the crushing process of waste glass as the filling material for ascon, thereby reducing the cost of waste disposal of the conventional waste glass and reducing the cause of pollution. It is to be.

이를 위해서는 당연히 폐유리 분말이 아스콘용 채움재로서 과연 우수한 물성을 가지는가에 대하여 시험을 통한 입증이 필요할 것인바, 이하에서는 그 시험 내 용 및 결과에 관하여 상세히 설명한다.To this end, it will be necessary to prove whether the waste glass powder has excellent physical properties as a filling material for ascon. Hereinafter, the test contents and results will be described in detail.

시방서가 규정하는 모든 기준을 만족하고 있으며, 특히 0.6 내지 0.15mm의 입도 범위에 걸쳐 모두 100에 가까운 값을 보이므로, 입도 분포 측면에서는 석회 석분 및 제강 더스트에 비해 더욱 우수한 물성을 갖는 것으로 나타났다.It satisfies all the criteria specified by the specification, and especially, the value close to 100 over the particle size range of 0.6 to 0.15mm, it was shown to have more excellent physical properties in terms of particle size distribution than lime lime powder and steelmaking dust.

도시된 바와 같이, 안정도(N)의 경우, 석회 석분에 비해서는 부족하지만 제강 더스트에 비해서는 우수한 것으로 나타났으며, 흐름값(0.01cm)의 경우, 석회 석분, 제강 더스트에 비해 가장 우수한 것으로 나타났다.As shown, the stability (N) was insufficient compared to the lime lime powder, but excellent compared to the steelmaking dust, the flow value (0.01cm), it was shown to be the best compared to the lime lime powder, steelmaking dust. .

표 7,8은 교통 하중에 대한 균열 저항성을 모사하기 위한 간접인장강도 시험의 결과를 나타낸 것이다.Tables 7 and 8 show the results of indirect tensile strength tests to simulate crack resistance against traffic loads.

도로포장 구조물은 외기에 노출되어 교통 하중에 의해 끊임없이 반복적인 하중의 재하를 받는다는 대단히 불리한 환경에 놓이게 되므로, 일단 포장 구조물에 균열이 발생하면 수분 기타 유해 물질의 유입, 동결과 융해의 반복, 상술한 교통 하중의 반복 재하 등으로 인하여, 균열의 발전 속도 및 이에 따른 구조물의 손상 진행 속도가 타 구조물에 비해 훨씬 크다는 특징을 가진다.Road pavement structures are placed in a very unfavorable environment where they are exposed to outside air and are constantly subjected to repeated loads by traffic loads. Once a pavement is cracked, water and other harmful substances enter, repeat freezing and thawing, Due to the repeated loading of traffic loads, the generation speed of cracks and the damage progressing speed of the structure are much higher than those of other structures.

따라서, 도로포장 구조물은 타 구조물에 비해 특히 균열에 대한 저항성이 강조되는데, 이는 상술한 바와 같은 간접인장강도에 의해 측정된다.Therefore, the road pavement structure is emphasized in particular to the crack resistance compared to other structures, which is measured by the indirect tensile strength as described above.

표 7,8에 도시된 바와 같이, 본 발명에 의한 아스콘 조성물의 간접인장강도가 석회 석분, 제강 더스트에 비해 가장 우수한 것으로 나타났는데, 이는 상술한 도로포장 구조물의 특수성에 비추어 대단히 큰 의미를 갖는 것으로서, 본 발명에 의한 아스콘 조성물의 물성이 기존의 석회 석분, 제강 더스트에 비해 오히려 우수하다는 유력한 증거가 되는 것이다.As shown in Table 7,8, the indirect tensile strength of the asphalt concrete composition according to the present invention was found to be the most excellent compared to lime lime, steelmaking dust, which has a very significant meaning in view of the specificity of the road pavement structure described above. , It is to be a potent evidence that the physical properties of the asphalt concrete composition according to the present invention, rather than the existing lime lime powder, steelmaking dust.

이와 같이 폐유리 분말이 채움재로서 적용된 아스콘 조성물의 물성이 우수한 이유는, 다음과 같이 2가지 이유에 의한 것으로 추론할 수 있다.Thus, the reason why the ascon composition which waste glass powder applied as a filler is excellent in the physical property can be deduced by the following two reasons.

첫째, 폐유리 분말의 거친 형상이 Interlocking 작용을 강화하기 때문이다.First, the rough shape of the waste glass powder enhances the interlocking action.

폐유리 분말은 기본적으로 경도가 높은 SiO2를 기본재료로 하는 것이고, 그 생산과정에 있어서도 열처리 공정 등이 전혀 없이 오로지 폐유리 제품의 파쇄, 분쇄 공정에 의해 생산되는 방식을 취하므로, 생산된 폐유리 분말의 표면은 매우 거친 형상을 취할 수밖에 없다.Waste glass powder is basically made of SiO 2 with high hardness, and in the production process, it is produced by crushing and crushing waste glass products without any heat treatment process. The surface of the glass powder has a very rough shape.

따라서, 이와 같이 거친 형상의 폐유리 분말이 아스팔트 바인더 및 골재와 혼합되는 경우, 입자 상호간의 Interlocking 작용을 강화할 수 있다.Therefore, when the coarse waste glass powder is mixed with the asphalt binder and the aggregate, the interlocking action between the particles can be enhanced.

둘째, 입도 분포가 우수하기 때문이다.Second, the particle size distribution is excellent.

상기 표 1에 나타난 바와 같이, 폐유리 분말을 채움재로 적용한 아스콘 조성물은 시방서가 규정하는 모든 입도 범위에 걸쳐 모두 100에 가까운 값을 보이고 있는데, 폐유리 분말은 이러한 특징으로 인하여 아스팔트 바인더 및 골재 사이의 공극에 빠짐없이 골고루 분포될 수 있는 것이다.As shown in Table 1, the ascon composition applied to the waste glass powder as a filler shows a value close to 100 over all the particle size range prescribed by the specification, the waste glass powder is due to this characteristic between the asphalt binder and aggregate It can be evenly distributed without falling into the voids.

결과적으로, 아스콘 조성물의 공극에 폐유리 분말이 골고루 분산되어 위와 같은 Interlocking 작용을 강화하므로, 결과적으로 조성물의 균열 저항성이 증대되는 것으로 파악되는 것이다.As a result, since the waste glass powder is evenly dispersed in the pores of the ascon composition to enhance the interlocking action as described above, it is understood that the crack resistance of the composition is increased as a result.

표 9,10은 포장체 수분 침투에 대한 내구성을 모사하기 위한 잔류 안정도 시험의 결과로서, 시방서(KS F 2349)가 규정하는 요건을 만족하는지 여부를 나타낸 것이다.Tables 9 and 10 show whether or not the requirements of the specification (KS F 2349) are satisfied as a result of the residual stability test to simulate the durability against package water penetration.

도로포장 구조물은 여름철 장맛비와 같은 우수의 영향을 직접적으로 받는 것이므로, 수분에 대한 저항성이 높을 것이 요구되는데, 위 시험 결과 잔류 안정도가 크다는 것은 이와 같은 수분에 대한 저항성이 높다는 의미가 된다.As the road pavement structure is directly affected by rainwater, such as summer rain, it is required to have high resistance to moisture, and the high residual stability of the above test means that this resistance to moisture is high.

표 9,10에 도시된 바와 같이, 본 시험의 경우에도 본 발명에 의한 아스콘 조성물이 종래의 채움재를 사용한 경우에 비해 잔류 안정도가 가장 우수한 것으로 나타났다.As shown in Table 9, 10, even in this test, the ascon composition according to the present invention was found to have the best residual stability compared to the case of using a conventional filler.

이와 같이 폐유리 분말이 채움재로서 적용된 아스콘 조성물의 잔류 안정도가 우수한 이유를 분석하면 다음과 같다.The reason why the residual glass stability of the ascon composition to which the waste glass powder is applied as a filler is excellent is as follows.
