본 발명은 고기능성 포러스 콘크리트에 관한 것으로 좀더 상세히는 포러스 콘크리트를 포설하고 그 포설된 콘크리트 표면에 SBR 라텍스 고무, NBR 등의 합성고무 또는 천연고무, SBS 에멀젼을 유화아스팔트에 혼합하여 0.1~10ℓ/㎡의 양으로 산포하여 제조되는 고기능성 포러스 콘크리트에 관한 것이다.The present invention relates to high-functional porous concrete, and more specifically, to install porous concrete and to the surface of the concrete, SBR latex rubber, synthetic rubber such as NBR or natural rubber, and SBS emulsion by mixing 0.1 to 10 l / ㎡ The present invention relates to a highly functional porous concrete produced by scattering in an amount of.

통상 종래의 도로포장은 불투수성인 아스팔트 또는 콘크리트 포장으로 되어 있다. 그런데, 이러한 불투수성 포장은 강우시 빗물이 도로에 잔류하여 교통에 장애가 되며, 차량 제동시 미끄러지는 문제점이 있어 사고의 위험을 증가시킨다. 또한, 빗물이 지하로 침투되지 못하여 하천을 범람시키는 원인이 되는 등 여러 가지 문제점이 있다.Conventional road pavement is usually an impermeable asphalt or concrete pavement. However, such an impervious pavement has a problem in that rainwater remains on the road during rainfall, which impedes traffic, and there is a problem of slipping when braking the vehicle, thereby increasing the risk of an accident. In addition, there are various problems such as rainwater does not penetrate underground, causing flooding of rivers.

또한, 도시가 증가, 확장되면서 아스팔트, 콘크리트 포장으로 수분이 자연적으로 땅속으로 침투하는 것을 막게 되어 지하수량이 급격히 감소하고 이로 인하여 지반 침하, 수목의 발육 둔화, 생태 변화가 일어난다. 따라서 도로 포장시 우수가 지층으로 침투될 수 있는 시공 방법이 고려되어야 한다. 종래 도시개발 및 조경공사를 함에 있어서 빗물을 지중으로 침투시킬 목적으로 다양한 투수성 포장이 개발되어 왔다.In addition, as the city expands and expands, it prevents water from penetrating into the ground naturally with asphalt and concrete pavements, which causes a rapid decrease in the amount of groundwater, resulting in ground subsidence, slowing the growth of trees, and ecological changes. Therefore, construction methods that can infiltrate rainwater into the strata should be considered. Various permeable pavements have been developed for the purpose of infiltrating rainwater into the ground in urban development and landscaping.

기존의 투수성 콘크리트의 경우에는 투수성 아스팔트와 같이 기후에 따른 변성은 일어나지 않으나 먼지 등의 오염원에 의하여 공극이 쉽게 막히며, 투수성 아스팔트에 비하여 표면 탈리현상이나 소음이 크고 미끄럼 저항이 낮아 제동거리가 길어, 특히 빗길 등에서 사고의 위험이 따르는 문제점이 있고, 강도가 약해 일반 도로에 사용하는 데 한계가 있다.Conventional water-permeable concrete does not occur due to climate change, like water-permeable asphalt, but pores are easily blocked by pollution sources such as dust, and have a higher surface detachment or noise and lower sliding resistance than water-permeable asphalt. There is a problem that the risk of accidents, especially in the rain, such as long, there is a limit to use on a general road due to the weak strength.

상기 문제점을 해결하기 위하여 본 발명은 포러스 콘크리트를 포설하고 그 표면에 천연고무 또는 합성고무 등을 함유하는 유화아스팔트 혼합물을 산포하여 투수성은 유지하면서도 표면탈리현상을 방지하고 소음감소 효과와 미끄럼 저항을 높이는 포러스 콘크리트를 제공하는 것을 목적으로 한다.In order to solve the above problems, the present invention distributes emulsified asphalt mixture containing natural rubber or synthetic rubber on the surface of the porous concrete and prevents surface detachment while maintaining water permeability and improving noise reduction effect and sliding resistance. It is an object to provide porous concrete.

또한, 본 발명의 다른 목적은 포러스 콘크리트의 표면에 산포시 콘크리트 기공의 막힘현상이 없이 공극이 그대로 유지되며, 표면탈리현상이 현저히 저감되고 소음방지효과가 미끄럼저항을 높이는 천연고무 또는 합성고무를 함유한 유화아스팔트 혼합물을 제공하는 것이다.
In addition, another object of the present invention is to maintain the voids without clogging of the concrete pores when sprayed on the surface of the porous concrete, the surface desorption phenomenon is significantly reduced and the noise prevention effect contains a natural rubber or synthetic rubber to increase the sliding resistance One emulsified asphalt mixture is provided.

상기 목적을 달성하기 위하여 본 발명자는 기존의 포러스 콘크리트를 포설하고 표면에 천연고무 또는 합성고무 등을 함유한 유화아스팔트 혼합물을 산포하여 포러스 콘크리트의 공극은 그대로 유지되면서 소음과 표면 탈리현상 등을 감소시킨 포러스 콘크리트를 제조하였다. 제조된 포러스 콘크리트는 45kgf/㎠ 이상의 휨강도와 15%이상의 공극율을 나타내었다.In order to achieve the above object, the present inventors laid down existing porous concrete and scattered emulsion asphalt mixture containing natural rubber or synthetic rubber on the surface to reduce noise and surface detachment while maintaining voids of the porous concrete. Porous concrete was prepared. The produced porous concrete showed flexural strength of more than 45kgf / ㎠ and porosity of more than 15%.
