Abstract
Description
본 발명은, 시멘트 콘크리트층과, 상기 시멘트 콘크리트층 상부에 시공되는 아스팔트층으로 이루어지는 도로에서 상기 시멘트 콘크리트층과 아스팔트층을 결합시키는 결합 첨가제에 관한 것이다.The present invention relates to a bonding additive for bonding a cement concrete layer and an asphalt layer to a road comprising a cement concrete layer and an asphalt layer formed on the cement concrete layer.
일반적으로 종래의 도로 공사 방법은 일정 깊이만큼 땅을 판 다음, 바닥면에 배수를 위해 자갈 및 큰 골재를 깔고 그 위에 작은 골재를 쌓은 다음 맨 위에 흙을 덮어 지반이 안정될 때까지 일정 기간이 흐른 후에 아스팔트 공사를 하였다.Generally, in the conventional road construction method, the ground is piled up to a certain depth, the gravel and the large aggregate are laid on the floor for drainage, the small aggregate is piled on the ground, and the soil is covered on the top, Later, asphalt was built.
그러나, 최근에는 이러한 공사 기간을 단축하기 위해 흙 위에 일정량의 콘크리트 구조물을 형성한 후 바로 아스콘을 도포함으로써 아스팔트 공사를 하고 있다.However, in recent years, in order to shorten the construction period, a certain amount of concrete structure is formed on the soil, and the asphalt is applied by applying the asphalt immediately.
그런데, 이러한 시공 방식에서 아스팔트층과 기저층인 콘크리트 구조물 사이의 접합이 완벽히 이루어지지 못해서 비 또는 결빙에 의해 결합력이 약해져 박리가 되는등 여러 문제점이 대두되어, 이를 해결하고자 여러 기술이 개발되고 있다.However, in such a construction method, since the bonding between the asphalt layer and the concrete structure as the base layer is not completely performed, various problems such as peeling due to weakening of cohesive force due to rain or freezing have arisen, and various techniques have been developed to solve this problem.
일예로, "매스틱 아스팔트 포장용 혼합물 및 그 제조방법"(한국 등록특허공보 제10-1896102호, 특허문헌 1)에는 시멘트 콘크리트 상측에 연속으로 방식층, 접착층을 형성하고 그 위에 아스팔트 포장을 실시하는 시공 방식이 제시되어 있으며, 아스팔트 포장층은 아스팔트 바인더 조성물과 골재가 혼합하여 구성되고, 접착제는 에폭시 아스팔트계로 이루어진 구성이 공개되어 있다.For example, in "Mastic Asphalt Paving Mixture and Method for Manufacturing the Same" (Korean Patent Registration No. 10-1896102, Patent Document 1), an adhesive layer is continuously formed on the upper side of cement concrete and asphalt pavement is formed thereon The asphalt pavement layer is composed of an asphalt binder composition and an aggregate, and the adhesive is composed of an epoxy asphalt layer.
또, "구스 아스팔트 조성물 및 이를 이용한 도로포장방법"(한국 등록특허공보 제10-1784950호, 특허문헌 2)에는 콘크리트 구조물과 노면을 형성하는 아스팔트콘크리트 사이에 구스 아스팔트와 코팅층을 연설하는 공법이 공개되어 있다.In addition, a method of addressing goose asphalt and a coating layer between a concrete structure and an asphalt concrete forming a road surface is disclosed in "Goos Asphalt Composition and Road Paving Method Using the Same" (Korean Patent Registration No. 10-1784950 and Patent Document 2) .
그러나, 상기한 특허문헌 1과 2는 시멘트 콘크리트 구조물과 아스팔트 사이에 시공되는 첨가제의 제조와 시공이 어려울 뿐만 아니라, 품질 역시 높지 않아 더 많은 개선이 필요한 실정이다.However, the above-mentioned Patent Documents 1 and 2 are not only difficult to manufacture and construct additives between the cement concrete structure and the asphalt, but also require a lot of improvement because the quality is not high.

전처리 방식을 적용하여 공사를 할 경우에는 공사 기간이 늘어나 전체 공사 비용이 증가하는 측면의 어려움이 있다.When the pre-treatment method is applied, there is a difficulty in increasing the construction cost because the construction period is increased.

사진에 나타나 있는 바와 같이 첨가제가 섞인 아스팔트와 시멘트 벽돌의 틈새를 막아 접촉 면적을 확대시킨 것으로 나타났으며, 시멘트 벽돌에 아스팔트가 부착된 상태에서 손으로 문질러 본 결과 묻어나지 않는 것을 확인하였다.As shown in the photograph, it was found that the contact area was enlarged by blocking the gap between the asphalt and the cement bricks mixed with the additives, and it was confirmed that the cement brick was not rubbed by the hand rubbing with the asphalt attached.
[실험예 2][Experimental Example 2]
콘크리트 블록을 준비한 후, 실험예 1과 같이 동일하게 접착제를 도포 후 경화시켜 보았다.After the concrete block was prepared, the adhesive was applied in the same manner as in Experimental Example 1 and then cured.

순수한 시멘트 몰탈을 제조하여 바닥면에 도포한 후 양생시켜 콘크리트를 직접 제조하였으며, 제조된 콘크리트 위에 실시예의 아스팔트에 첨가제를 혼합한 것 도포하였다.Pure cement mortar was prepared and applied to the bottom surface and cured to prepare concrete directly. The prepared concrete was coated with an additive mixed with the asphalt of the example.
도 3의 좌상측은 제조된 콘크리트를, 우상측은 아스팔트에 첨가제를 혼합한 것을 도포한 후의 상태를 나타낸 것이며, 좌하 및 우하부는 아스팔트에 첨가제를 혼합한후 도포한 상태를 나타낸 사진이다.The upper left side of FIG. 3 shows the manufactured concrete, the upper right side shows a state after the mixture of the additives with the asphalt, and the lower left and lower right portions shows the state after the additives are mixed with the asphalt.
도 3의 우하측의 세 샘플은 좌측에서 우측으로 실시예 7 내지 9를 나타낸 것이며, 좌하측의 샘플은 실시예 2 및 6을 나타낸 것이다.Three samples on the lower right side of Fig. 3 show Examples 7 to 9 from left to right, and samples on the lower left side show Examples 2 and 6. Fig.
이 경우에도 아스팔트에 첨가제를 혼합한 것이 제조한 시멘트 콘크리트로부터 분리되지 않는 것을 확인하였다.In this case, it was confirmed that the mixture of asphalt and additives was not separated from the cement concrete.
한편, 상기 실험예 2와 동일한 방식으로 콘크리트 블록에 비교예 1 내지 9에서 제조된 접착제를 도포한 후 150℃ 이상의 온도에서 아스팔트를 도포하는 실험을 실시하였다.Meanwhile, in the same manner as in Experimental Example 2, the adhesive prepared in Comparative Examples 1 to 9 was applied to the concrete block, and then the asphalt was applied at a temperature of 150 ° C or more.
그 결과 비교예 1 내지 9의 경우 아스팔트에 첨가제를 혼합한 것을 손으로 문질렀을 때 콘크리트 블록으로부터 쉽게 떨어져나가는 것을 확인하였다.As a result, in the case of Comparative Examples 1 to 9, it was confirmed that the mixture of the additives in the asphalt easily separated from the concrete block when rubbed by hand.
더하여, 실험예 2에 의해 제조된 콘크리트 블록 시편과, 상기 비교 실험으로 제조된 콘크리트 블록 시편을 준비한 후 KS F 2386에 따른 부착강도 측정 실험을 하였다.In addition, the concrete block specimens prepared in Experimental Example 2 and the concrete block specimens prepared in the above comparative experiment were prepared, and then the adhesion strength was measured according to KS F 2386.
그 결과는 아래 표 3에 나타난 바와 같다.The results are shown in Table 3 below.
상기한 실험에서 나타난 바와 같이 실시예들의 경우 전체적으로 콘크리트 블록 표면에 아스콘의 부착강도가 높게 나타났으며, 실시예 9의 경우 가장 높게 나타났다.As shown in the above experiment, the adhesion strength of the ascon was high on the concrete block surface as a whole in the case of Examples, and it was the highest in Example 9.
반면, 비교예들의 경우 전체적으로 실시예에 비해 부착강도가 낮게 나타났으며, 특히 습윤 상태에서는 현저하게 나타났다.On the other hand, the bonding strengths of the comparative examples were lower than those of the examples in the whole, and they were remarkable especially in the wet state.
이는 습윤 상태에서의 시공시 부착력이 전혀 발생하지 않아 기건 상태에서만 시공되어야 하는 문제점을 갖게 되는 것으로 시공시 약 150℃이상의 고온이 필요한 것으로 보인다.This is because the adhesive force is not generated at all during the construction in the wet state, and therefore, it is required to be applied only in the state of construction.
이처럼 본 발명에 따른 결합 첨가제를 이용하여 접착제를 아스팔트에 섞어 제조한 후 이를 시공해본 결과 본 발명에 따른 결합 첨가제는 포장 작업시 도막 방수층을 형성하여 물과 습기의 침투를 방지하도록 할 뿐만 아니라, 콘크리트 구조체에 미세한 크랙이나 균열이 발생하여도 이에 대응할 수 있는 이음매 역할을 담당하고, 유기 및 무기계 첨가제 영향으로 알칼리나 산성 물질의 영향을 받지 않아 콘크리트를 보호하여 내구성을 향상시키는 것으로 판단된다.As a result, it has been found that the bonding additive according to the present invention can prevent permeation of water and moisture by forming a waterproof layer of a coating film during the packaging operation, It is believed that it acts as a joint that can cope with micro cracks and cracks in the structure and protects the concrete because it is not influenced by alkali or acid due to the influence of organic and inorganic additives, thereby improving the durability.
