도로포장의 덧씌우기 공법{RECOVERY METHOD FOR CONCRETE PAVEMENT}Road paving method {RECOVERY METHOD FOR CONCRETE PAVEMENT}

본 발명은 도로 포장분야에 관한 것으로서, 상세하게는, 노후된 도로포장을 보수하기 위한 공법에 관한 것이다.The present invention relates to the field of road pavement, and more particularly, to a construction method for repairing old road pavement.

노후화된 기존의 콘크리트 포장을 보수하기 위한 공법은 크게 아스팔트 덧씌우기와 콘크리트 덧씌우기로 대별할 수 있다.The technique for repairing aging concrete pavement can be roughly divided into asphalt overlay and concrete overlay.

콘크리트 덧씌우기 공법은 장기간의 공용성을 갖는다는 장점이 있으나, 기존 포장과의 부착강도가 우수하지 못하다는 점, 그 양생 시간이 길어 장시간 교통차단을 해야 한다는 점 등의 단점이 있다.The concrete overlay method has the advantage of having long-term commonality, but it has disadvantages such as poor adhesion strength with the existing pavement, long curing time, and long traffic blocking.

이에 비해, 아스팔트 덧씌우기 공법은 포설 후 비교적 단시간 내에 교통개방이 가능하고, 기존 포장과의 부착이 우수하다는 장점이 있으나, 공용기간이 짧아 재보수가 필요한 경우가 많고 반사균열이 발생한다는 단점이 있다.On the other hand, the asphalt overlay method has the advantage of being able to open traffic in a relatively short time after installation and excellent adhesion with the existing pavement, but it is often disadvantageous that the repair period is necessary due to the short period of use and reflection cracking occurs. .

현재까지는 위의 두 공법 중 후자인 아스팔트 덧씌우기 공법이 일반적으로 사용되어 왔으나, 공용기간이 너무 짧고, 잦은 재보수 공사로 인한 불편함이 문제로 지적되어 왔는바, 장기간의 공용성을 갖는 콘크리트 덧씌우기 공법의 단점을 개선하기 위한 고안이 절실히 요청되어 왔다.So far, the latter asphalt overlay method has been generally used. However, it has been pointed out that the period of common use is too short, and the inconvenience caused by frequent renovation work is a problem. There is an urgent need for devising to improve the disadvantages of the process.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 장기간의 공용성을 확보하면서도, 기존 포장과의 부착강도가 우수하고, 조기 교통개방이 가능하도록 하는 도로포장의 덧씌우기 공법을 제시하는 것을 그 목적으로 한다.The present invention has been made to solve the above problems, and to provide a road paving method to ensure the long-term commonality, excellent adhesion strength with existing pavement, and enables early traffic opening. The purpose.

상기 보강재(200)는 반원형 단면의 이형철근(210)이고, 상기 보강재 설치단계는 상기 반원형 단면의 이형철근(210)의 편평한 면이 상기 기존 도로포장(100)의 표면에 면접촉하도록 설치하는 것이 바람직하다.The reinforcement 200 is a deformed reinforcement 210 of the semi-circular cross section, the reinforcement installation step is to install so that the flat surface of the deformed reinforcement 210 of the semi-circular cross section in surface contact with the surface of the existing road pavement 100. desirable.

상기 덧씌우기단계에서 적용되는 시멘트 콘크리트는 조강, 초조강 또는 초속경 시멘트를 사용하는 것이 바람직하다.As the cement concrete applied in the overlaying step, it is preferable to use crude steel, crude steel or cemented carbide.

본 발명은 장기간의 공용성을 확보하면서도, 기존 포장과의 부착강도가 우수하고, 조기 교통개방이 가능하도록 하는 도로포장의 덧씌우기 공법을 제시한다.The present invention proposes a road paving method that ensures long-term commonality, excellent adhesion strength with existing pavement, and enables early traffic opening.

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.

도 1 이하에 도시된 바와 같이, 본 발명에 의한 도로포장의 덧씌우기 공법은 기본적으로, 기존 도로포장(100)의 표면을 처리하는 표면처리단계; 표면처리된 기존 도로포장(100) 상면에 보강재(200)를 설치하는 보강재 설치단계; 보강재(200)가 설치된 표면에 시멘트 콘크리트를 타설하여 덧씌우기층(300)을 형성하는 덧씌우기단계;를 포함하여 구성된다.As shown in Figure 1, the road paving method according to the present invention is basically a surface treatment step of treating the surface of the existing road pavement 100; Reinforcement installation step of installing the reinforcement 200 on the surface of the existing road pavement 100 surface treatment; It is configured to include; an overlay step of forming the overlay layer 300 by pouring cement concrete on the surface of the reinforcement 200 is installed.

즉, 기존 포장(100)의 상면에 시멘트 콘크리트를 타설하여 덧씌우기층(300)을 형성하기 전, 기존 포장(100)의 상면에 보강재(200)를 설치함으로써, 기존 포장(100)과 덧씌우기층(300)의 부착을 우수하게 하고, 덧씌우기층(300) 자체의 강도도 강화하도록 한 것이다.That is, before forming the overlay layer 300 by pouring cement concrete on the upper surface of the existing pavement 100, by installing the reinforcement 200 on the upper surface of the existing pavement 100, the existing pavement 100 and the overlaying layer ( The adhesion of the 300 is excellent, and the strength of the overlay layer 300 itself is also enhanced.

따라서 본 발명에 의한 공법은 시멘트 콘크리트에 의한 덧씌우기 방식을 취하므로 기본적으로 장기간의 공용성을 가지면서도, 종래 콘크리트 덧씌우기 공법에서 부착강도가 우수하지 못하다는 단점을 극복하도록 한다는 효과가 있다.Therefore, the method according to the present invention takes the overlaying method by cement concrete and has the effect of overcoming the disadvantage that the adhesion strength is not excellent in the conventional concrete overlapping method even though it has basically a long-term commonality.

여기서, 보강재(200)는 이형철근을 선형 또는 격자형으로 배치하여 사용할 수 있다.Here, the reinforcement 200 may be used to arrange the deformed rebar in a linear or lattice form.

다만, 일반 이형철근은 원형 단면을 가지므로, 기존 포장(100)과의 접촉 면적이 좁음에 따라, 부착강도가 좋지 못할 우려가 있다.However, since the general deformed reinforcing bar has a circular cross section, as the contact area with the existing pavement 100 is narrow, there is a fear that the adhesion strength is not good.

따라서 도 3에 도시된 바와 같이, 보강재(200)로서 반원형 단면의 이형철근(210)을 적용하고, 이러한 반원형 단면의 이형철근(210)의 편평한 면이 기존 도로포장(100)의 표면에 면접촉하도록 설치함으로써, 우수한 부착강도를 얻도록 하는 것이 바람직한 것이다.Therefore, as shown in FIG. 3, a deformed rebar 210 having a semi-circular cross section is applied as the reinforcement 200, and a flat surface of the deformed rebar 210 having such a semi-circular cross section is in surface contact with the surface of the existing pavement 100. It is desirable to obtain a good adhesion strength by installing so as to.

기존 포장(100)과 보강재(200) 및 덧씌우기층(300)의 부착을 우수하게 하기 위해서는, 덧씌우기 작업에 앞서 기존 도로포장(100)의 표면의 이물질을 제거하는 표면청소단계를 포함하는 것이 바람직하다.In order to improve the adhesion of the existing pavement 100 and the reinforcement 200 and the overlay layer 300, it is preferable to include a surface cleaning step of removing foreign matter on the surface of the existing road pavement 100 prior to the overlay operation. Do.

이후, 부착력을 더욱 우수하게 하기 위해서는, 도 2에 도시된 바와 같이, 기존 도로포장(100)의 표면에 요철을 형성하는 것이 바람직하다.Then, in order to further improve the adhesion, it is preferable to form the irregularities on the surface of the existing road pavement 100, as shown in FIG.

이는 미세한 크기의 강재 볼을 도로 표면에 고압분사하는 방식(shot blasting 공법) 등에 의해 구현할 수 있다.This can be implemented by a method of high pressure spraying the steel ball of fine size on the road surface (shot blasting method).

덧씌우기에 의해 도로포장(100)의 높이가 높아지면 곤란한 경우(예컨대 교량 하부에서 일정 범위 내의 형하고를 유지해야 하는 경우)에는, 기존 도로포장(100)의 표면을 일정 깊이(L)까지 절삭하고, 상기 청소 또는 요철 형성작업을 실시하는 것이 바람직하다.When the height of the road pavement 100 is increased due to the overlaid (for example, when the mold must be maintained within a certain range in the lower part of the bridge), the surface of the existing road pavement 100 is cut to a predetermined depth (L). It is preferable to perform the cleaning or irregularities forming operation.

이는 노면절삭기에 의해 기존 포장(100)의 표면을 절삭하는 방식(cold milling 공법) 등에 의해 구현할 수 있다.This may be implemented by a method of cutting the surface of the existing pavement 100 by using a road cutter (cold milling method).

종래 콘크리트 덧씌우기 공법의 단점 중, 양생시간이 길다는 문제를 해소하기 위해서는, 조강, 초조강 또는 초속경 시멘트를 사용하는 것이 필요한데, 위 보강재(200)는 이러한 시멘트를 사용한 콘크리트의 문제점인 소성수축, 건조수축에 의한 균열의 발생을 최소화하도록 한다.Among the disadvantages of the conventional concrete overlay method, in order to solve the problem of long curing time, it is necessary to use crude steel, crude steel or cemented carbide cement, the reinforcement 200 is a plastic shrinkage that is a problem of concrete using such cement Minimize the occurrence of cracks caused by dry shrinkage.

즉, 본 발명에 의한 공법에 있어서 위 보강재(200)는, 기존 포장(100)과의 부착강도를 높이는 역할, 조강 시멘트를 사용하는 경우 균열의 발생을 최소화하는 역할을 동시에 수행하는 것이다.In other words, in the construction method according to the present invention, the reinforcement 200 serves to increase the adhesion strength with the existing pavement 100, and simultaneously serves to minimize the occurrence of cracks when using the crude steel cement.

이상은 본 발명에 의해 구현될 수 있는 바람직한 실시예의 일부에 관하여 설명한 것에 불과하므로, 주지된 바와 같이 본 발명의 범위는 위의 실시예에 한정되어 해석되어서는 안 될 것이며, 위에서 설명된 본 발명의 기술적 사상과 그 근본을 함께 하는 기술적 사상은 모두 본 발명의 범위에 포함된다고 할 것이다.Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above It will be said that both the technical idea and the technical idea which together with the base are included in the scope of the present invention.
