Description

탄력성과 투수성이 우수한 경량 아스콘 포장재{Asphalt-paved materials}Lightweight Ascon Packaging Material with Excellent Elasticity and Permeability {Asphalt-paved materials}

본 발명은 발포 펄나이트 또는 발포 질석을 이용하여 탄력성과 투수성이 우수한 경량 아스콘 포장재에 관한 것이다.The present invention relates to a lightweight ascon packaging material excellent in elasticity and water permeability using expanded pearlite or expanded vermiculite.

도로 포장재에 있어서 일반적으로 널리 쓰여지고 있는 기존의 아스팔트 혼합물은 KSF 2349(한국 표준규격)에서 규정한 가열혼합 가열포설 역청포장용 혼합물이며, 대다수의 포장재로 쓰이고 있다.Existing asphalt mixtures, which are widely used in road pavement materials, are mixtures for hot mixed bitumen pavement pavement specified in KSF 2349 (Korean Standard) and are used for the majority of pavement.

이 혼합물은 아스팔트의 쇄석골재, 모래들이 배합기준에 따라 150∼170℃ 사이에서 기계식 강제 혼합시설(아스팔트 믹싱 프랜트)에서 생산되어 덤프트럭 등 운반수단에 의해 시공현장에 보내지며 현장에서의 시공온도는 125℃이상에서 피니셔, 로울러 포장공 등에 의해 포설되어 적절한 다짐을 통해서 차량이나 기타의 교통수단의 등급에 따라 시공되어 진다.This mixture is produced in the mechanical forced mixing facility (asphalt mixing plant) between asphalt and crushed aggregate and sand according to the mixing standards and sent to the construction site by means of transport such as dump truck. It is installed by finisher, roller packer, etc. above 125 ℃, and it is constructed according to the grade of vehicle or other means of transportation through proper compaction.

그리고 결합재로 쓰여지는 아스팔트 용재인 AP-3(아스팔트 기준 등급)가 한국에서 주로 쓰여지고 있으며, 이것에 대한 규정은 KSM 2201(도로포장용 아스팔트 규격)에서 규정하고 있다.Asphalt grade AP-3 (Asphalt standard grade) used as binder is mainly used in Korea, and the regulation on this is prescribed in KSM 2201 (Road Paving Asphalt Specification).

종래 아스콘재로만 도포가 되어 포장되는 경우,투수성이 없어 비가오게 되면 지반이 쉽게 약화되어 도로의 손실이 생기고,탄력성이 없어 주행감이 좋지않고,도보시 쉽게 발이 피로해지는 점이 있었고 또한, 열이나 강도에 약하고, 특히 하절기에는 쉽게 열변형되어 도로의 상태가 균일하지 못하고 울퉁불퉁하게 되는 원인이 되어 각종 사고의 원인을 제공하는 문제점이 있었다.Conventionally, it is only coated with ascon material, and if it rains because of no permeability, the ground is easily weakened, resulting in loss of roads, lack of elasticity, poor driving feeling, and fatigue on foot. It is vulnerable, in particular in the summer, the heat is easily deformed to cause a state of the road is uneven and uneven, there was a problem of providing various causes of accidents.

또, 강도에 약한 관계로 약간의 충격으로도 파손되어 주행감을 저하시킴과 아울러 사고의 원인이 되는등의 폐단이 있었던것이다.In addition, due to its weak strength, it was damaged even with a slight impact, reducing the driving feeling and causing an accident.

따라서, 약 2-4년 정도를 주기로 하여 훼손된 도로를 자주 보수하거나, 새로히 포장하는 작업이 이루어지는 바, 개인은 물론 국가적으로 많은 경제적인 피해를 주고 있는 실정이다.As a result, the damaged roads are frequently repaired or newly paved every two to four years, which causes many economic damages not only to individuals but also to the nation.

상기와 같은 문제점을 개선하고자 각종 폐기물을 활용하여 도로포장재로 사용함으로써 강도를 높이고 폐기물 재활용이라는 장점을 살리기고자 폐기물이나 폐타이어 등의 첨가제를 더 포함시킨 포장재가 제시되고 있다.In order to improve the problems described above, to improve the strength by using a variety of waste as a road paving material and to take advantage of the waste recycling has been proposed a packaging material further containing additives such as waste or waste tires.

이러한 산업 폐기물로 그 처리가 심각한 폐합성수지나 유리 등을 포장재의 첨가재로서 이용하게 되므로, 폐기물 재활용 측면에서 유용한 효과가 있다.Since such industrial waste uses waste synthetic resin or glass, which is seriously treated, as a packaging material, there is a useful effect in terms of waste recycling.

그렇지만, 폐기물을 직접 도로포장재로서 활용할 수 없고, 폐기물을 특정하게 가공하여 폐기물 분말을 제조해야 하므로, 폐기물 처리가 어렵고 또한 도로의 장기간 사용 및 파손시 포장재에 포함되어 있는 폐기물이 분진으로 발생하여 오히려 인체나 환경에 악영향을 미칠수 있는 우려가 있다.However, since waste cannot be directly used as a road paving material, and the waste powder must be manufactured by processing the waste specifically, it is difficult to dispose of the waste, and in the case of long-term use and breakage of the road, the waste contained in the pavement material is generated as dust, rather than human body. I have a concern that may adversely affect the environment.

따라서 ,본 발명의 목적은 도로 포장재의 탄력성과 투수성를 향상시켜 주행감을 향상시킴은 물론 강도를 높여서 수명 연장을 할 수 있도록 한 경량 아스콘를 제공한다.Accordingly, an object of the present invention is to provide a lightweight ascon to improve the elasticity and permeability of the road pavement to improve the running feeling as well as to increase the strength to extend the life.

또한,본 발명은 자갈이나 모래등과 아스콘을 혼합하는 아스콘 포장재에 있어서, 발포 펄나이트와 발포 질석을 혼합하여 포장재를 제공함으로써, 포장된 도로의 탄력성, 투수성,강도를 높여 주행성과 미끄럼 방지등을 할 수 있도록 한 경량 아스콘를 제공한다.In addition, the present invention, in the asphalt concrete mixing gravel, sand, etc., and ascon, by mixing foamed pearlite and expanded vermiculite to provide a paving material, to increase the elasticity, water permeability, strength of the paved road, running and slipping, etc. Provide a lightweight ascon to help you.

또한, 발포 펄나이트 , 발포 질석등은 스티로폴처럼 가벼우므로 비중이 낮아 운반비가 적게 들어 경비가 절감되는 아스콘포장재을 제공한다.In addition, foamed pulmonite, expanded vermiculite, etc. are as lightweight as styropol, so the specific gravity is low, thus providing ascon packaging material with low transportation cost.

본 발명은 펄나이트 또는 질석 중 어느1종 또는 2종을 혼합하여 소정 크기로 분쇄하고, 그 분쇄된 입자들을 700 ~ 1200℃ 급가열 팽창시켜 발포체를 제조한다음 상기 제조된 펄나이트 또는 질석 중 어느1종 또는 2종를 혼합하여 선택한 발포체 10~95중량%와 골재 1~10중량% ,아스팔트 4~7중량%를 혼합하여 이루어진다.The present invention is a mixture of any one or two of the pearlite or vermiculite is pulverized to a predetermined size, the crushed particles 700 to 1200 ℃ rapid thermal expansion to produce a foam and then any of the prepared pulrite or vermiculite It is made by mixing 10 to 95% by weight of the selected foam, 1 to 10% by weight of aggregate, 4 to 7% by weight of asphalt, by mixing one or two types.

발포펄나이트(진주암),발포질석(버미큘나이트)는 약 760~1200℃의 고온에서 급가열시키면 함유된 휘발성분이 가스화하여 연화된 입자의 내부에서 팽창하면서 기공을 형성하게되 광석 원석부피에 비해 10~30배까지 팽창되는 것이다.When foamed pearlite (pearlite) and foamed stone (vermiculite) are rapidly heated at a high temperature of about 760-1200 ° C, the volatiles contained in them gasify and expand in the softened particles to form pores. It is expanded up to 10-30 times.

이는 광석에 포함된 2~6%정도의 수분이 기인하는 것으로 마치 팝콘을 만드는 원리와 같이 펄라이트나 질석을 팽창시키는 것으로, 팽창될 때 눈처럼 하얀 각각의 알갱이들은 아주 많은 작은 기포들로 채워지고, 그 알갱이 표면은 작은 공극들로 뒤덮여 있기 때문에 아주 큰 표면적을 갖게 되므로 아스팔트에 첨가하는 경우 탄력성과 투수성이 향상되고 더나아가 강도도 증진된다.This is due to 2 ~ 6% moisture contained in the ore. It expands pearlite or vermiculite, just like the principle of making popcorn. When expanded, each grain of snow white is filled with many small bubbles. Since the grain surface is covered with small voids, it has a very large surface area, which, when added to asphalt, improves its elasticity and permeability, and furthermore its strength.

상기 발포펄나이트(진주암),발포질석(버미큘나이트)의 발포체 입자의 입도(粒度)는 5 - 50메쉬가 적당하며 아스콘 전체 조성물에 대해 10-95중량%부로 포함된다. 발포체를 10중량%이하 첨가 하는 경우는 탄력성과 투수성이 약하고, 95중량%이상 첨가할 때는 강도가 약한 문제점이 있다.The particle size of the foamed particles of the expanded pearlite (pearlite) and foamed stone (vermiculite) is preferably 5 to 50 mesh and is included in an amount of 10 to 95% by weight based on the total composition of ascone. When the foam is added below 10% by weight, the elasticity and water permeability are weak, and when added above 95% by weight, the strength is weak.

골재는 20㎜이하의 자갈,석회석,석분,더스트를 혼합하여 1~10중량% 사용함으로서 원하는 탄력성과 투수성과 우수한 아스콘을 제조할 수 있다.Aggregate can be used as a blend of gravel, limestone, stone powder, dust of less than 20mm 1 ~ 10% by weight to produce the desired ascones excellent elasticity and permeability.

이들 상기한 조성물들에 섞여 응결된 상태로 상호 결합이 이루어지도록 하는 응결재로 아스팔트가 포함된다.As a coagulant to be mixed with these above compositions in a coagulated state, the coagulant includes asphalt.

또한, 아스콘은 이미 알고 있는 바와 같이 고온에서는 액체상태로 용융되며, 상온에서는 응고되며 강한 접착력을 갖게 된다.In addition, ascon is melted in a liquid state at a high temperature as it is known, and solidified at room temperature and has a strong adhesive force.

따라서, 상기한 발포 펄나이트 또는 발포 질석 입자들과, 골재분말, 모래를 소정의 배율로 마련한 후 아스콘을 이에 혼합하고 약 200℃내외의 고온으로 가열하는 것에 의해 혼합된 각 조성물들의 사이로 아스콘이 용융되며 섞여지고, 고온을 유지한 상태에서 포장작업이 이루어진 후 자연냉각에 의해 응고되어 평편히 도로 포장된 상태를 유지할 수가 있는 것는 것으로, 본 발명의 아스콘에 의한 그 제조공정은 다음과 같다.Therefore, ascon is melted between the above-mentioned expanded pulmonite or expanded vermiculite particles, aggregate powder and sand at a predetermined magnification, and then mixed with ascon and heated to a high temperature of about 200 ° C. After being mixed and mixed and maintained at a high temperature, the packaging is solidified by natural cooling to maintain a flat packed state, and the manufacturing process by the ascon of the present invention is as follows.

모래, 쇄석등의 골재와 발포펄나이트 또는 발포질석 중 어느1종 또는 2종을 혼합하여 선택한 발포체를 입도별로 가열로에 투입하여 110 ~180℃ 온도로 가열하여 핫빈에서 체가름을 하는 제1단계,The first step of mixing sieves in hot bins by mixing selected one or two types of aggregates such as sand, crushed stone and foamed pulverite or foamed stone into the heating furnace by particle size and heating them to 110 ~ 180 ℃ ,

아스팔트를 140 ~180℃로 가열하는 제2단계Second step of heating the asphalt to 140 ~ 180 ℃

상기 제1단계의 가열골재와 발포체를 제2단계의 가열아스팔트와 믹싱혼합하여 아스콘를 제조하여 포장하는 단계로 구성된다,Mixing and mixing the heating aggregate and the foam of the first step with the heating asphalt of the second step is composed of the step of producing and packaging ascon,
