Abstract
본 고안은 환경오염을 발생시키는 산업폐기물인 폐 아스콘을 재활용한 도로포장에 관한 것으로 종래의 투수아스콘(이하 "투수콘"이라 한다)은 골재에 아스팔트를 가열하여 도포한 연성포장이다 보니 일조에 의해 아스팔트가 유동하여 포장체의 공극이 메워저 투수성의 효력은 상실되고 강도 또한 약하여 포장재로서의 실효성을 거두지 못하고 있는가 하면 폐 아스콘 포장은 아스팔트 가열로 인한 고비용과 소성변형으로 내구성에 많은 문제점이 있었다.The present invention relates to a road pavement that recycles waste ascon, which is an industrial waste that causes environmental pollution. Conventional pitched ascon (hereinafter referred to as "pitcher") is a flexible pavement coated by heating asphalt to aggregates. As the asphalt flows to fill the voids in the pavement, the effect of permeability is lost and the strength is also weak, and the effectiveness of the pavement is not achieved. The waste ascon pavement has many problems in durability due to high cost and plastic deformation due to asphalt heating.
본 고안은 이러한 문제점을 해결하기 위한 방법으로 폐 아스콘을 수거하여 분쇄기로 골재번호7호 규격으로 분쇄하여 도로포장재를 준비하였다.The present invention prepared a road paving material by collecting waste ascon as a method for solving this problem by crushing to the aggregate No. 7 standard with a grinder.
이렇게 분쇄된 폐 아스콘 골재의 입도 규격은 19mm체를 100% 통과하고 13mm체를 90-100%통과하고 10mm체를 40-70%통과하고 5mm체를 0-15%통과하고 2.5mm체를 0-5%통과하는 공정으로 이루어진 재활용 골재로서 이러한 규격의 재활용 골재를 이용한 도로포장재는 제1단계로 분쇄된 폐 아스콘 골재와 아스팔트유화제를 믹서에 넣어 혼합하여 아스팔트유화제가 폐 아스콘 골재의 표면에 충분히 도포되게 하고 제2단계로는 시멘트와 혼화재를 믹서에 넣어 아스팔트유화제가 도포된 폐 아스콘 골재와 혼합되도록 한 후 제3단계로 신골재와 물 그리고 유기첨가제로 수용성고분자폴리머를 안료등과 믹서에 투입하여 상온에서 충분히 혼합시켜서 형성된 포장재이다.The particle size specification of crushed waste ascon aggregate is 100% through 19mm sieve, 90-100% through 13mm sieve, 40-70% through 10mm sieve, 0-15% through 5mm sieve, and 0- 2.5mm sieve As a recycled aggregate consisting of 5% pass, the road paver using recycled aggregate of this standard is mixed with waste asphalt asphalt aggregate and asphalt emulsifier in the mixer in the first stage so that the asphalt emulsion can be sufficiently applied on the surface of waste asphalt concrete. In the second step, cement and admixture are put in a mixer to be mixed with the asphalt asphalt emulsifier-coated waste ascon aggregate, and in the third step, new aggregate, water, and organic additives are added to a water-soluble polymer in a pigment and a mixer. It is a packaging material formed by mixing sufficiently in
이렇게 형성된 포장재는 보도나 자전거도로 산책로 광장 주차장등 경 차량이 통행하는 도로와 차도의 표층용으로 사용하여도 내구성이 강하여 소성변형이 발생하지 않는 폐 아스콘을 재활용한 도로포장을 제공하게 되는 것이다.The pavement material formed as described above provides road pavement that recycles waste ascon which is durable even when used for the surface layer of roads and driveways through which light vehicles pass such as sidewalks, bicycle paths, promenades, parking lots, etc., and does not cause plastic deformation.
Description
본 고안은 폐 아스콘을 재활용한 도로포장에 관한 것으로 보다 상세하게는 분쇄된 폐 아스콘골재에 아스팔트유화제를 도포하고 여기에 시멘트와 혼화재를 혼합한 후 신골재,물,유기첨가제,안료 등을 투입하여 상온에서 충분히 혼합시켜 형성된 도로포장에 관한 것이다.The present invention relates to a road pavement that recycled waste ascon. More specifically, asphalt emulsifier is applied to crushed waste ascon aggregate, and cement and admixture are mixed therein, and new aggregates, water, organic additives, pigments, etc. It relates to a road pavement formed by sufficiently mixing at room temperature.
일반적으로 아스콘은 아스팔트와 시멘트가 결합된 포장인데 연성의 포장이다 보니 수명이 약하여 유지관리비가 많이 들어 경제성에 문제가 있는가 하면 재시공 시 폐 아스콘의 처리가 산업폐기물로 분류되어 환경오염을 발생시키므로 이러한 폐 아스콘을 도로포장의 재활용골재로 사용하는 방법을 연구하는 과정속에 노화된 아스콘을 수거하여 입도별로 분쇄한 후 아스콘공장에서 가열하면서 신골재와 개질제,충진제 등을 첨가 혼합하여 도로의 포장재로 사용하여왔으나 이 공법 역시 폐 아스콘을 가열하여 사용하는 것이므로 아스팔트의 성분인 침입도와 신도 등의 하락으로 소성변형이 발생하는가 하면 가열을 위한 고비용으로 경제성에 만족하기 어려웠다.In general, ascon is a pavement that combines asphalt and cement. It is a soft pavement. As a result, it has a weak lifespan and high maintenance costs. Therefore, there is a problem in economics. In the process of researching how to use ascone as recycled aggregate for road pavement, aged ascone was collected and pulverized by particle size, and it was used as pavement by adding new aggregate, modifier and filler while heating at Ascon plant. Since this method is also used to heat the waste ascon, plastic deformation occurs due to the decrease in penetration and elongation, which is a component of asphalt, and it is difficult to satisfy the economics at high cost for heating.
따라서 이러한 폐 아스콘의 문제점을 해결하기위하여 폐 아스콘을 도로포장재의 기본골재로 사용할 수 있는 제품이 여러 종류 제안된 바 있다.Therefore, in order to solve the problem of the waste ascon has been proposed a number of products that can be used as a basic aggregate of the road paving material.
예를 들면 대한민국 특허공보(공보번호10-0243926,분쇄 폐 아스콘을 이용한 도로포장용 콘크리트 및 그 제조방법)에 기재된 특허청구범위를 살펴보면 40mm체에서 100%통과하고,25mm체에서 95-100%통과하고,13mm체에서25-60%통과하고,5mm체에서 0-10%통과하고,2.5mm체에서 0-5%통과하는 입도규격으로 분쇄된 폐 아스콘(10)과 고형분100%를 기준으로 1-5%의 유화아스팔트를 혼합하여 유화아스팔트(20)가 분쇄 폐 아스콘(10)의 표면에 도포되도록 하는 공정;전기 공정의 유화아스팔트(20)가 도포된 분쇄 폐 아스콘(10)에 시멘트(30)250-500kg/㎥를 혼합하는 공정; 및 전기공정의 유화아스팔트(20) 및 시멘트(30)가 혼합된 분쇄 폐 아스콘(10)에 분쇄 아스콘 량의 10-50%에 해당하는 5mm이하의 모래,폐 아스콘량의 50%이하에 해당하는 굵은골재, 물-시멘트비가 20-50%인 물,시멘트 사용량의 0.8%이하의 감수제를 투입,혼합하여 슬럼프가 0-10cm가 되도록 하는 공정;을 포함하는 분쇄 폐 아스콘을 이용한 도로포장용 콘크리트 제조방법을 제안하고 있으나 이러한 폐 아스콘을 이용한 도로포장용 콘크리트 제조방법은 폐 아스콘을 수거하여 골재번호57호 입도규격으로 분쇄하여 아스콘포장의 기층 및 보조기층재로 재활용하고 있으나 아스콘포장의 표층에서 발생되고 있는 소성변형으로 인한 거북이 등 현상을 억제할 수 있는 효과를 갖어오지는 못했다.For example, if you look at the patent claims described in the Republic of Korea Patent Publication (Publication No. 10-0243926, road paving concrete using crushed waste ascon and its manufacturing method), it passes 100% in 40mm, 95-100% in 25mm Based on the size of the granulated waste ascon (10) and the solid content 100%, which passes 25-60% in a 13mm sieve, 0-10% in a 5mm sieve, and 0-5% in a 2.5mm sieve. Mixing 5% emulsified asphalt so that the emulsified asphalt 20 is applied to the surface of the pulverized waste asphalt concrete 10; cement 30 to the pulverized waste asphalt asphalt 10 coated with emulsified asphalt 20 of the electrical process Mixing 250-500 kg / m 3; And 50 mm or less of sand or waste ascon which corresponds to 10-50% of the amount of crushed ascone in the pulverized waste ascon 10 in which the emulsified asphalt 20 and cement 30 of the electrical process are mixed. Coarse aggregate, water-cement ratio 20-50% water, 0.8% or less water-cementing agent is added to the mixing, mixing step to make the slump 0-10cm; including the method of manufacturing concrete for road paving However, the method of manufacturing concrete for road pavement using waste ascon is collected from waste ascon and crushed into aggregate No. 57 particle size standard and recycled as base and auxiliary base material of ascon pavement, but plastic deformation occurs in surface layer of ascon pavement. Turtles, etc. due to the phenomenon has not been able to suppress.
본 고안은 이와 같은 문제점을 개선하기 위하여 안출된 것으로 환경오염을 발생시키는 산업폐기물인 폐 아스콘을 골재번호7호 입도 규격으로 분쇄하여 골재의 표면에 아스팔트유화제를 충분히 도포하고 여기에 시멘트와 혼화재를 혼합시키면서 신골재,물,유기첨가제,안료 등과 결합이 용이하게 될 수 있도록 믹싱하여 얻어진 재활용포장재로서 내구성이 강하며 소성변형이 없는 개량된 포장재를 제공하는 것을 목적으로 하였다.The present invention was devised to improve such a problem. The waste ascon, which is an industrial waste that causes environmental pollution, was crushed to the aggregate No. 7 particle size standard to sufficiently apply the asphalt emulsifier to the surface of the aggregate, and mixed cement and admixture with it. The purpose of the present invention is to provide an improved packaging material that is durable and free of plastic deformation as a recycled packaging material obtained by mixing so as to be easily combined with new aggregates, water, organic additives, and pigments.
또한 이러한 혼합물로 형성된 포장은 가열포장이 아니고 상온포장이므로 폐 아스콘을 가열함에 따른 고비용을 절감할 수 있어 경제적으로 큰 이점이 있으며 산업폐기물인 폐 아스콘을 재활용하여 포장재로 사용함으로서 폐 아스콘으로 인한 환경오염을 방지하고 자원을 얻을 수 있는 환경친화적인 도로포장재임을 입증하기 위한 것이다.In addition, the packaging formed by such a mixture is not a heating package but a room temperature package, so it is possible to reduce the high cost of heating the waste ascon, which is a great economic advantage. It is to prove that it is an environmentally friendly road paver that can prevent and obtain resources.
본 고안은 폐 아스콘골재,아스팔트유화제,시멘트,혼화재,신골재,물,유기첨가제,안료 등을 소정의 비율로 혼합하여 포장재를 형성시킨 폐 아스콘을 재활용한 도로 포장으로서 골재는 2.5mm미만의 입자가 결여된 13mm미만의 재활용골재를 사용하여 배합되는 것을 특징으로 하였다.The present invention is a road pavement recycling waste ascon aggregate formed by mixing waste ascon aggregate, asphalt emulsifier, cement, admixture, new aggregate, water, organic additives, pigment, etc. It characterized in that it is formulated using less than 13mm recycled aggregates.

By adding water and an organic additive (12) and mixing the water-soluble polymer and the pigment (14) to form a packaging material for recycling the waste ascone.
이렇게 형성된 폐 아스콘골재(02)의 입도 규격은 19mm체를 100%통과하고,13mm체를 90-100%통과하고,10mm체를 40-70%통과하고,5mm체를 0-15%통과하고,2.5mm체를0-5통과하는 공정으로 이루어진 재활용골재이다.The particle size specification of the waste ascon aggregate (02) thus formed is 100% through 19mm sieve, 90-100% through 13mm sieve, 40-70% through 10mm sieve, 0-15% through 5mm sieve, Recycled aggregate consisting of 0-5 passes through 2.5mm sieve.
이하 본 고안의 폐 아스콘을 재활용한 도로 포장을 실시 예에 의거 설명한다.Hereinafter will be described based on the embodiment of the road pavement recycled waste ascon of the present invention.
가)재활용포장재의 배합과정A) Mixing process of recycled packaging materials
수거한 폐 아스콘을 골재번호7호 규격으로 분쇄한 후 폐 아스콘골재 760-850kg/㎥에 아스팔트유화제를 24-36kg/㎥믹서에 투입하여 혼합하였고 이어서 시멘트360-450kg/㎥와 플라이애쉬 18-24kg/㎥를 투입하여 혼합한 후 골재번호7호 규격의 신골재 860-980kg/㎥,물108-140kg/㎥,유기첨가제25-33kg/㎥,안료7-10kg/㎥등을 투입하여 상온에서 혼합함으로서 폐 아스콘을 재활용한 포장재가 형성되는 것이다.The collected waste ascon was crushed to aggregate No.7 standard and asphalt asphalt emulsifier was mixed into 24-36kg / ㎥ mixer to 760-850kg / ㎥ of waste ascon aggregate, followed by mixing cement 360-450kg / ㎥ and fly ash 18-24kg. After mixing / ㎥ added new aggregate 860-980kg / ㎥, aggregate 108-140kg / ㎥, organic additives 25-33kg / ㎥, pigment 7-10kg / ㎥, etc. mixed at room temperature By doing so, a packaging material for recycling waste ascon is formed.
나)시공B) Construction
가)항의 과정으로 배합된 재활용포장재는 슬럼프가 2cm이하이므로 담프트럭으로 운송을 하며 포장면을 다짐을 할 때에는 가열포장이 아닌 상온포장이므로 상온롤라를 이용하여 다짐을 한 후 콘크리트포장의 시방과 같이 비닐로 덮어 양생을 시킨다.The recycled packing material blended in the process of paragraph a) has a slump of less than 2cm, so it is transported by a damp truck and when it is packed, it is a normal temperature package, not a heating package. Cover with vinyl to cure.
이와같은 공정으로 완성된 포장은 콘크리트의 양생기간이 지난 후 캇타기로 길이3-5m간격으로 캇팅을 하고 이어서 실리콘을 주입한 후 포장의 표면에 표면처리 강화제를 살포하여 폐 아스콘을 재활용한 포장을 완성시킨다.After the curing period of concrete, the finished paving process is cut by 3 ~ 5m length with a cutter.
