본 발명은 토목 분야에 관한 것으로서, 상세하게는 배수성 아스팔트 포장체를 보수, 보강하기 위한 공법에 관한 것이다.The present invention relates to the field of civil engineering, and more particularly, to a method for repairing and reinforcing drainage asphalt pavement.

본 발명은 토목 분야에 관한 것으로서, 상세하게는, 배수성 아스팔트 도로를 형성하는 배수성 아스팔트 포장체의 내구성 향상, 소음저감 및 차열성을 증진시키기 위한 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of civil engineering, and more particularly, to a method for improving durability, reducing noise and thermal insulation of a drainage asphalt pavement forming a drainage asphalt road.

도 1에 도시된 바와 같이, 배수성 아스팔트 포장체(10)는 배수성 표층(11), 기층(12), 보조기층(13)에 의한 층상구조를 취한다.As shown in FIG. 1, the drainage asphalt pavement 10 has a layered structure by the drainage surface layer 11, the base layer 12, and the auxiliary base layer 13.

이들 중 아스팔트 포장체의 표층(11)을 구성하는 재료에는 아스팔트와 골재를 혼합한 배수성 아스팔트 혼합물이 사용되며, 통상의 공극률은 20% 내외가 되도록, 아스팔트 바인더와 골재의 배합비가 결정된다.Among them, a drainage asphalt mixture obtained by mixing asphalt and aggregate is used as a material for the surface layer 11 of the asphalt pavement, and the mixing ratio of the asphalt binder and the aggregate is determined so that the usual porosity is about 20%.

배수성 아스팔트 포장의 가장 큰 특징은 종래의 일반 아스팔트 포장(공극률 6% 내외)에 비해 공극률이 20% 내외로 높아 자동차 주행시의 바퀴와 포장면 사이에 발생되는 파열음을 흡수하여 기존 아스팔트 포장에 비해 소음을 2dB(방음벽 1개 설치 효과와 유사함) 이상 감소시킬 수 있고, 우천시 포장 표면의 물을 단시간에 배수함으로서 수막현상에 의한 미끄럼 저항을 억제하여 교통사고 발생을 줄일 수 있는 점이다.The biggest feature of the drainable asphalt pavement is that the porosity is around 20% compared to the conventional asphalt pavement (with a porosity of about 6%). It is possible to reduce more than 2dB (similar to the effect of installing one soundproof wall) and to reduce the occurrence of traffic accidents by suppressing the sliding resistance caused by water film phenomenon by draining water on the pavement surface in a short time in rainy weather.

그러나, 현장에서 시공하는 과정에서 품질관리의 미흡 등으로 인하여, 아스팔트 함량이 부족한 경우, 세골재 및 석분의 함량 등이 부족한 경우, 다짐이 부족한 경우 등이 빈번하게 발생한다.However, due to the lack of quality control in the process of construction in the field, when the asphalt content is insufficient, the fine aggregate and stone content is insufficient, such as the lack of compaction frequently occurs.

이는 배수성 아스팔트 포장체의 표면에 작용하는 교통하중에 의해, 골재가 포장체로부터 탈리되는 현상, 수분의 침투에 의한 균열 및 포트홀 등과 같은 조기 파손을 발생시키는 요인이 된다.This is a factor that causes premature failure, such as a phenomenon in which the aggregate detaches from the pavement, cracks and potholes due to moisture infiltration, due to the traffic load acting on the surface of the drainage asphalt pavement.

이러한 손상이 발생하는 경우, 종래에는 특별한 보수, 보강공법이 개발된 바 없으므로, 기존의 배수성 표층재료를 절삭 제거한 다음, 그 위에 재포장을 실시하는 것이 일반적이었다.In the case where such damage occurs, conventional repair and reinforcement methods have not been developed in the past, so it was common to cut off the existing drainable surface material and then repack it.

그러나, 이러한 종래의 보수공법은 많은 비용이 소모되고, 공사에 긴 시간이 소요되므로 사용자의 불편을 초래하는바, 사회적 비용손실이 크다는 점에서 문제로 지적되어 왔다.However, such a conventional repair method has been pointed out as a problem in that a large cost is consumed and a long time is required for construction, causing inconvenience to the user, and a large social cost loss.

또한 아스팔트 포장을 도심지에 적용할 경우 태양광에 의한 일사 에너지에 의해 한 여름철에는 포장의 온도가 최대 60oC까지 상승하게 되므로 대기온도를 상승시켜 도심지의 열섬효과를 유발하게 하는 문제가 있어 여름철 쾌적한 도심환경을 유지하는데 큰 장애 요소로 작용하고 있다.In addition, when the asphalt pavement is applied to urban areas, the temperature of the pavement rises up to 60 o C during the summer due to solar energy caused by sunlight. Therefore, there is a problem of causing the heat island effect of urban areas by raising the atmospheric temperature. It is a major obstacle to maintaining the urban environment.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 적은 비용 및 시간의 소요에 의해 배수성 아스팔트 포장체를 효율적으로 보수 및 보강할 수 있으면서, 부수적으로 추가적인 소음감소 효과와 여름철 도심지에서 발생되는 열섬현상을 저감할 수 있도록 하는 고탄성 MMA 수지 및 이를 이용한 배수성 아스팔트 포장체의 보강공법을 제시하는 것을 그 목적으로 한다.The present invention has been made to solve the above problems, while being able to efficiently repair and reinforce the drainage asphalt pavement due to the low cost and time required, incidentally additional noise reduction effect and heat island generated in the summer downtown The purpose of the present invention is to propose a high elastic MMA resin and a method for reinforcing drainage asphalt pavement using the same.

이하, 첨부도면을 참조하여 본 발명의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 의한 배수성 아스팔트 포장체의 보강공법은 기본적으로, 배수성 아스팔트 포장체(10)의 표면에 존재하는 이물질 및 손상된 포장조각을 제거하는 표면 청소단계; 배수성 아스팔트 포장체(10)의 표면에 고탄성 MMA 수지를 살포하여 보강층(100)을 형성하는 보강층 형성단계; 보강층(100)의 상면에 칩 골재(200)를 살포하는 칩 골재 살포단계; 상기 보강층(100)의 상면에 고탄성 MMA 수지를 살포하여 차열층(300)을 형성하는 차열층 형성단계;를 포함하여 구성된다.The reinforcement method of the drainage asphalt pavement according to the present invention basically includes a surface cleaning step of removing foreign matter and damaged pieces of pavement existing on the surface of the drainage asphalt pavement 10; Reinforcing layer forming step of forming a reinforcing layer 100 by spraying a high elastic MMA resin on the surface of the drainage asphalt pavement (10); Chip aggregate spraying step of spraying the chip aggregate 200 on the upper surface of the reinforcing layer 100; And a heat shield layer forming step of forming a heat shield layer 300 by spraying high elastic MMA resin on the upper surface of the reinforcing layer 100.

여기서, 고탄성 MMA 수지란, MMA에 PMMA, Butyl Acrylate, 무기 바인더를 첨가한 합성수지로서, MMA(Methyl Methacrylate) 40~55 중량%, PMMA(Polymethyl Methacrylate) 15~28 중량%, Butyl Acrylate 15~28 중량%, 무기바인더 0.1~2 중량 %의 배합을 취하는 경우, 아스팔트 혼합물과의 결합력이 우수하고, 1시간 이내 완전 경화가 가능하며, 내구성 및 내화학성, 내마모성, UV 안정성 등의 물성이 탁월하여, 골재의 비산이나 균열의 발생 등을 효과적으로 억제한다는 특성이 있다.Here, the highly elastic MMA resin is a synthetic resin in which PMMA, Butyl Acrylate, and inorganic binder are added to the MMA, 40-55 wt% MMA (Methyl Methacrylate), 15-28 wt% PMMA (Polymethyl Methacrylate), and 15-28 wt% Butyl Acrylate %, Inorganic binder 0.1 ~ 2% by weight, excellent binding strength with asphalt mixture, fully curable within 1 hour, excellent properties such as durability and chemical resistance, wear resistance, UV stability, aggregate There is a characteristic that it effectively suppresses the scattering and the occurrence of cracks.

종래의 일반적인 MMA 수지는 수지 량의 2~5% 정도 소량의 경화제를 첨가하면 경화를 시작하는데, 경화 개시 후 1시간 이내에 완전히 경화가 완료되는 초속경성 수지이고, 통상 작업 가능시간은 20분 내외로서 작업성이 우수하여 넓은 면적에 포 설 및 마무리를 수행할 수 있다.Conventional general MMA resin is cured when adding a small amount of hardener of about 2 to 5% of the amount of resin, and is a super fast curing resin that is completely cured within 1 hour after the start of curing, and usually the working time is about 20 minutes. Excellent workability allows the installation and finishing of a large area.

이러한 MMA수지는 경화 후 그 강도가 대단히 우수하나 내균열성 및 휨추종성이 부족할 뿐만 아니라 바탕체와의 열팽창 특성이 상이함으로 인해, 실내가 아닌 야외에서 사용할 경우 균열이 발생하기 쉽다는 단점이 있다.The MMA resin is very excellent in strength after curing but lacks crack resistance and bending trackability, and also has a disadvantage in that cracks are likely to occur when used outdoors instead of indoors due to different thermal expansion characteristics with the substrate.

또한 종래의 MMA 수지는 일반적으로 아스팔트 포장체에 도포하기 전에 별도의 접착제를 도포하여야 하므로 시공시간이 오래 소요되고 비용이 많이 드는 단점이 있다.In addition, conventional MMA resin has a disadvantage in that it takes a long time and costly construction because a separate adhesive must be applied before applying to the asphalt pavement in general.

본 발명에 의한 고탄성 MMA 수지는 MMA수지에 PMMA, Butyl Acrylate, 무기 바인더 등을 첨가함으로써, 위와 같은 종래의 MMA 수지의 단점을 극복한 것이다.The high elastic MMA resin according to the present invention overcomes the disadvantages of the conventional MMA resin by adding PMMA, Butyl Acrylate, an inorganic binder, and the like to the MMA resin.

이러한 고탄성 MMA 수지는 인장강도가 2MPa 이상이면서 인장파괴시의 신장률이 50% 이상으로 종래의 MMA수지에 비해 신장률이 5배 이상 우수하여, 아스팔트 포장체에 도포할 경우 내균열성 측면에서 상당히 유리하다. The high elastic MMA resin has a tensile strength of 2 MPa or more and an elongation at break of 50% or more, and an elongation of 5 times or more is superior to that of conventional MMA resins. .

또한 무기바인더의 첨가로 인하여 자체 접착기능이 있어 별도의 접착제 도포 없이 아스팔트 포장체에 직접 도포가 가능하므로, 시간과 비용을 상당히 절감할 수 있다는 효과가 추가된다.In addition, the addition of the inorganic binder has a self-adhesive function can be applied directly to the asphalt pavement without a separate adhesive, it is added to the effect that can significantly save time and cost.

무기바인더로는, 다이에틸알릴포스페이트, 히도록시에틸메타아크릴레이트포스페이트, 히드록시에틸아크릴레이트포스페이트, 비스(2-히드록시에틸메타크릴레이트)산포스페이트, 2-히드록시에틸메타크릴레이트산포스페이트, 트리스(2-히드록시에틸메타크릴레이트)산포스페이트 등의 재질을 단독으로 또는 혼합하여 사용할 수 있다.As the inorganic binder, diethyl allyl phosphate, hygiethyl ethyl methacrylate phosphate, hydroxyethyl acrylate phosphate, bis (2-hydroxyethyl methacrylate) acid phosphate, 2-hydroxyethyl methacrylate phosphate, Materials such as tris (2-hydroxyethyl methacrylate) acid phosphate can be used alone or in combination.

본 발명에 의한 고탄성 MMA 수지는 20℃에서의 점도가 100~300MPas인 것이 좋고, 중합반응 공정을 거친 반응성 수지를 사용하는 것이 더욱 바람직하다.It is preferable that the high elastic MMA resin by this invention is 100-300 Mpa of viscosity in 20 degreeC, and it is more preferable to use the reactive resin which passed the polymerization reaction process.

위 보강층 형성단계에서 사용되는 고탄성 MMA 수지 보강재의 살포량은 300~700g/m2 정도가 적절한 것으로 나타났다.The spraying amount of the high elastic MMA resin reinforcing material used in the above reinforcing layer forming step was found to be about 300 ~ 700g / m 2 appropriate.

MMA 수지만을 코팅할 경우 포장의 표면이 너무 미끄럽기 때문에, 미끄럼 방지 성능을 높이기 위하여 보강층(100)의 상면에 칩 골재(200)를 살포한다.When only the MMA resin is coated, the surface of the package is too slippery, so that the chip aggregate 200 is sprayed on the upper surface of the reinforcing layer 100 to increase the anti-slip performance.

이러한 칩 골재(200)는 세라믹 골재, 실리카, 제강슬래그, 등의 재질을 단독으로 또는 혼합하여 사용할 수 있다.The chip aggregate 200 may be used alone or mixed with materials such as ceramic aggregate, silica, steel slag, and the like.

종래 미끄럼 방지를 위해 사용되는 골재는 대부분 직경이 2mm 이상이므로, 미끄럼 방지효과는 있으나, 골재의 입경이 커 소음이 유발되고 차량 바퀴와의 마찰력이 집중되어 탈리가 쉽게 발생되거나 코팅된 수지를 포장의 표면으로부터 탈리되게 하는 문제를 유발하였다. Aggregates used for conventional non-slip, most of the diameter is more than 2mm, so there is an anti-slip effect, but the particle size of the aggregate is large, noise is generated and frictional force with the vehicle wheel is concentrated easily desorption or coated resin It caused the problem of detachment from the surface.

본 발명에 의한 보강공법은 이러한 칩 골재(200)의 직경을 0.5~1mm로 제한함으로써, 미끄럼 저항기능은 종래 수준으로 유지하면서 상기 언급한 문제를 해소할 수 있도록 하였다. The reinforcement method according to the present invention by limiting the diameter of the chip aggregate 200 to 0.5 ~ 1mm, so as to solve the above-mentioned problems while maintaining the sliding resistance function to the conventional level.

이러한 칩 골재(200)의 살포량은 300~700g/m2 정도가 적절한 것으로 나타났다.The spreading amount of the chip aggregate 200 was found to be about 300 ~ 700g / m 2 is appropriate.

이와 같이 칩 골재(200)가 살포된 보강층(100)의 상면에는, 근적외선을 반사할 수 있는 안료가 포함된 상기 고탄성 MMA 수지를 살포함으로써 차열층이 형성된 다.In this way, a heat shielding layer is formed on the upper surface of the reinforcing layer 100 to which the chip aggregate 200 is sprayed by spraying the high-elastic MMA resin containing a pigment capable of reflecting near infrared rays.

이러한 차열성 MMA 수지는 상기 고탄성 MMA 수지에 태양광에 의해 포장표면으로 방사되는 근적외선을 반사할 수 있는 안료를 첨가한 것으로서, 여름철 포장의 표면온도를 최대 10oC 정도 저하시켜 주위의 대기온도를 2~3oC 떨어뜨릴 수 있는 차열성 도료의 역할을 할 수 있다.The heat-resistant MMA resin is a pigment that can reflect the near-infrared rays radiated to the pavement surface by sunlight to the high-elastic MMA resin, reducing the surface temperature of the summer packaging up to about 10 o C to reduce the ambient air temperature Can act as a thermal barrier paint that can be dropped 2 to 3 o C.

여기서, 안료는 중공 세라믹 분말 등을 사용하는 것이 좋고, 이는 고탄성 MMA 수지 중량 대비 10~15 중량% 정도를 사용하는 것이 적절한 것으로 나타났다.Here, it is preferable to use a hollow ceramic powder or the like, and it is appropriate to use about 10 to 15% by weight based on the weight of the high elastic MMA resin.

차열층 형성단계의 고탄성(차열성) MMA 수지 보강재의 살포량은 300~700g/m2 정도가 적절한 것으로 나타났다.It was found that the spraying amount of the high elastic (heat shielding) MMA resin reinforcement in the heat shielding layer forming step was about 300 to 700 g / m 2 .

본 발명은 상술한 특성을 가진 재질을 이용한 배수성 아스팔트 포장체의 보강공법으로서, 배수성 아스팔트 포장체의 표면에 고탄성(차열성) MMA 수지 및 세라믹 골재를 살포하고 경화시켜, 배수성 아스팔트 포장체의 표면에 견고한 피막을 형성하는 것을 주된 특징으로 한다.The present invention is a reinforcement method of drainage asphalt pavement using the material having the above-described characteristics, by spraying and curing high-elasticity (heat shielding) MMA resin and ceramic aggregate on the surface of the drainage asphalt pavement, the surface of the drainage asphalt pavement The main feature is to form a firm film.

즉, 배수성 아스팔트 포장체의 표면에 살포된 고탄성 MMA 수지는 고점도 특성으로 인해 배수성 포장체의 공극은 유지하면서, 견고한 피막을 형성하므로, 배수성 아스팔트 포장체의 내마모성을 향상시키고, 골재의 비산 및 균열 발생 등을 억제함에 따라, 포장체의 조기 파손을 억제하고 공용수명을 연장할 수 있는 효과가 있다. That is, the high-elastic MMA resin sprayed on the surface of the drainage asphalt pavement forms a solid coating while maintaining the voids of the drainage pavement due to its high viscosity property, thereby improving the wear resistance of the drainage asphalt pavement and causing the scattering and cracking of aggregates. By suppressing the back, etc., there is an effect of suppressing premature breakage of the package and extending the service life.

또한 미세한 세라믹 골재를 살포함으로서 미끄럼 방지 기능 또한 부수적으로 기대할 수 있다. In addition, by spraying fine ceramic aggregates, anti-slip function can also be expected incidentally.

또한 배수성 포장 표면에 고탄성(차열성) MMA 수지를 코팅함으로서 종래의 배수성 아스팔트 포장에 비해 2dB 정도의 추가적인 소음감소 효과를 기대할 수 있으며, 차열성 MMA 수지에 의해 아스팔트 포장의 표면온도를 최대 10oC 정도 떨어뜨릴 수 있어 도심지 열섬효과를 완화할 수 있다.In addition, by coating a highly elastic (heat shielding) MMA resin on the surface of the drainable pavement, an additional noise reduction effect of about 2dB can be expected compared to the conventional drainable asphalt pavement, and the surface temperature of the asphalt pavement can be increased up to 10 o C by the heat shielding MMA resin. It can be reduced to reduce the heat island effect of downtown.

나아가, MMA 수지에 특정 색을 지닌 안료를 첨가하여 살포하는 경우, 아스팔트 포장체 표면에 다양한 색상을 구현할 수 있는데, 이는 버스 전용차로, 주차장, 보행자도로, 인터체인지 진입로 등의 구조물에 대하여, 경관이 우수한 배수성 포장의 형성을 가능하게 한다.In addition, when spraying by adding a pigment having a specific color to the MMA resin, it is possible to implement a variety of colors on the surface of the asphalt pavement, which is excellent for the structures such as bus lanes, parking lots, pedestrian roads, interchange access roads, etc. Enable the formation of drainage packages.

이하, 본 발명에 의한 고탄성 MMA 수지의 물성을 확인하기 위한 실시예에 대하여 설명한다.Hereinafter, the Example for confirming the physical property of the high elastic MMA resin by this invention is demonstrated.

표 1은 각각의 재료 구성비율을 달리하여 MMA 수지를 제조한 다음 탄산칼슘과 규사를 수지에 혼합하여 슬러리 형태로 제조하여 일축압축강도와 부착력 시험 등을 실시한 결과이다. Table 1 shows the results of MMA resins prepared by varying the composition ratio of each material, and then calcium carbonate and silica sand were mixed in the resin to prepare a slurry form to test uniaxial compressive strength and adhesion.

수지와 규사 및 탄산칼슘의 배합비율은 1:4.5이다. The blending ratio of resin, silica sand and calcium carbonate is 1: 4.5.

Figure 112009017778913-pat00001

비교예 1과 같이 MMA만 100% 사용한 수지의 경우, 압축강도는 다른 수지들에 비해 월등히 우수하나 파괴시 변형률이 낮아 취성파괴가 발생함을 알 수 있다. In the case of the resin using only 100% MMA as in Comparative Example 1, the compressive strength is significantly superior to other resins, but it can be seen that the brittle fracture occurs because the strain is low when breaking.

비교예 2는 Butyl Acrylate의 함량이 40%로 본 발명에서 제시하는 최대함량 28%를 초과하는 경우로서, 압축강도가 9MPa로 지나치게 낮고 상대적으로 파괴시 변형률도 낮아 강도 및 내균열성 측면에서 모두 불리한 것으로 나타났다.In Comparative Example 2, the content of Butyl Acrylate is 40%, exceeding the maximum content of 28% suggested in the present invention, and the compressive strength is 9MPa, which is too low and the deformation rate is relatively low, which is disadvantageous in terms of both strength and crack resistance. Appeared.

비교예 3의 경우 각 재료별 성분비가 본 발명의 제안범위 이내로서 압축강도가 미국의 ACI 코드에서 제시하는 아크릴계 폴리머 콘크리트의 일축압축강도 범위인 10~20MPa 범위내에 존재하고 파괴시 변형률도 비교예 1, 2에 비해 10배 이상 증대되어 연성이 대폭 강화되어 균열저항성이 우수함을 알 수 있다. In the case of Comparative Example 3, the component ratio of each material is within the proposed range of the present invention, and the compressive strength is present in the uniaxial compressive strength range of 10-20 MPa of the acrylic polymer concrete suggested by the US ACI code, and the strain at breakage is also Comparative Example 1 It can be seen that the crack resistance is excellent because the ductility is greatly enhanced by increasing 10 times or more compared to 2.

본 발명의 실시예는 비교예 3에 더하여 무기바인더를 첨가한 경우로서, 기본적 물성은 비교예 3과 유사하나, 특히 부착강도가 2배 이상 증가함을 알 수 있다.Example of the present invention is a case in which an inorganic binder is added in addition to Comparative Example 3, the basic physical properties are similar to Comparative Example 3, in particular, it can be seen that the adhesion strength increases more than two times.

표 2는 종래의 일반 배수성 아스팔트 포장체 상기 본 발명의 실시예가 코팅된 배수성 아스팔트 포장체의 물성에 관한 다양한 실내 및 현장 시험결과를 요약 정리한 것이다.Table 2 summarizes a variety of indoor and field test results related to the physical properties of the conventional general drainable asphalt pavement coated with an embodiment of the present invention.

Figure 112009017778913-pat00002
Figure 112009017778913-pat00002

표 2에 나타난 바와 같이, 본 발명에 의한 고탄성 MMA 수지를 적용하더라도 코팅 전 후의 공극률 및 투수계수는 큰 변화가 없어 배수성 포장의 배수기능은 잘 유지되는 것으로 나타났다. As shown in Table 2, even if the high-elastic MMA resin according to the present invention is applied, the porosity and permeability coefficient before and after coating are not significantly changed, and the drainage function of the drainable package is well maintained.

반면 골재의 탈리에 대한 저항성을 나타내는 칸타브로 손실률의 경우, 코팅 처리후 63.8%가 감소함에 따라 골재의 탈리에 의한 파손은 획기적으로 감소될 것으로 기대된다. On the other hand, in the case of the cantabros loss rate indicating the resistance to aggregate desorption, the breakage caused by the desorption of the aggregate is expected to be drastically reduced as the 63.8% decrease after the coating treatment.

또한 소성변형에 대한 저항성과 피로저항성도 획기적으로 증대됨을 알 수 있다. In addition, it can be seen that the resistance to plastic deformation and fatigue resistance are also significantly increased.

BPN(British Pendulum Tester)에 의한 미끄럼 저항성을 평가한 결과 코팅후 미끄럼 저항성이 상당히 증가함을 알 수 있다. As a result of evaluating the slip resistance by the British Pendulum Tester (BPN) it can be seen that the slip resistance after coating significantly increased.

또한 소음의 경우 코팅처리 후 약 2dB가 감소함에 따라 방음벽 1개를 추가로 설치하는 효과와 유사한 효과가 있음을 알 수 있다.In addition, the noise is reduced by about 2dB after the coating treatment, it can be seen that there is an effect similar to the effect of installing one additional sound barrier.
