Patterns of Road Repair Work and Case Studies with Photographs│What are the Advantages of Room Temperature Curing Repair Materials?

道路は日常的に自動車などが通行することで、摩耗や破損・欠損などが発生してしまいます。

破損などの発生はどうしても避けられないため、いかに対処していくかが重要です。放っておくと事故の原因にもなりかねないため、補修工事で破損などを修復していく対応が一般的です。

道路の補修工事には様々なものがありますが、常温合材が用いられることもあります。本稿では、道路の補修工事の中でも常温合材を使った工事が具体的にどういったものなのか、事例を通して説明していきます。
また、工事に適した補修材も合わせてご紹介するので、道路の補修を検討中の方は是非チェックしてください。

Repair work methods to fix road wear, damage, and deficiencies

When a road has a certain amount of wear, damage, or loss, repair work must be performed, and there are several ways to perform this repair work. Before we get into the main topic, we will first introduce three common methods of road repair work. Each has its own characteristics and disadvantages.

Request repair work from the contractor.

This method involves hiring a specialized repair contractor to perform pavement and road surface repair work. Naturally, this requires the time and effort to arrange for a contractor, and since heavy equipment may be used, it is necessary to confirm whether the site is suitable for the work. The cost of hiring a contractor to do the work will also be higher.

 

Purchase repair materials from home centers and other general retailers.

Asphalt repair materials can be purchased at home centers and e-commerce sites, so it is possible to deal with the problem without hiring a contractor. Although many of the materials available at such places are generally inexpensive, they are only for temporary use (emergency treatment) and are not durable enough. In addition, many of the materials are rough, and it tends to be difficult to finish them beautifully.

 

Purchase repair materials from a repair contractor to address the problem.

Another method is to purchase repair materials from a specialized repair business. Many repair materials are more expensive, but their durability and other performance characteristics are of a higher standard. It is also possible to achieve a beautiful finish, but this requires a certain level of familiarity with the material.

Example of road repair work using room temperature curing type repair material

From here, we will introduce examples of actual repair work using room temperature curing type repair materials through photographs.

Repair of steps in areas that have been repaired in the past

The room temperature curing type repair material can be easily applied to areas where complicated unevenness has occurred due to the use of repair materials in the past. As shown in the photo, even in areas where unevenness has occurred due to damage from previous repair materials, the repair material can be applied universally to smooth the road surface.

Puddle repair

It can also be used on areas where depressions and puddles occur, as shown in the photo below. Rounded wear areas such as depressions can also be flattened.

 

Repair large steps

Repairs can also be made to large, clearly defined bumps. It is important to repair such steps neatly, as they can cause accidents and further damage.

Repair rickety road surfaces

Many of you have probably seen rickety, worn-out road surfaces like the one in the photo. We can eliminate the bumps in these areas and achieve a flat surface.

Repair of defective parts

The room temperature curing type repair materials can be used for hole-shaped defects, cracks, and chipped areas as shown in the photo without any problem. It can also be used for holes that have become distorted, and even unevenly damaged areas can be finished beautifully.

Gutter Repair

Because gutters are not integral to the road, they are easily damaged and can be dangerous if left unattended, as shown in the photo. With room temperature cured repair materials, gutters can be repaired so that they are flush with the surrounding road.

KF Road Maintenance N" for road repair work

All of the repair work introduced as examples above uses a repair material called “KF Road Mente N”. KF Road Mente N is very suitable for road repair work among the many room temperature curing repair materials available. At the end of this paper, we will introduce the excellent performance of KF Road Mente N.

 

Easy to construct

KF Road Maintenance N has the following features that make it a very easy repair material to install.

• Powders and resins are easily mixed (stirring takes only 30 seconds)
• Low viscosity for easy spreading
• Hard to stick to the iron and hard to produce unevenness
• Low odor and no workload
• Washable with water only
• Less garbage generated.

 

High degree of freedom of construction

KF Road Maintenance N is very flexible in its application and can be used on any surface.

• Can be applied on wet road surfaces, etc.
• A thickness of about 10 cm can be applied at a time, allowing for quick repair of even deep repair areas.
• Particle size is small and can form smooth surfaces and slopes

 

Fast curing

Repair materials inevitably require time to cure due to their characteristics. KF Road Maintenance N can complete curing in the shortest time in the industry, thus improving work efficiency.

• Shortest curing time in the industry
• Realizes curing within about 40 minutes regardless of temperature
• Curing can be done quickly in any season at temperatures from 5 to 40℃.

 

Various property values are also good

KF Road Maintenance N is an ideal repair material with extremely high physical property values, which are the standard for durability.

• High adhesion strength
• High compressive strength
• High bending strength
• Slip resistance values are also high compared to typical roadways

summary

As described in this paper, road repair areas are subject to various types of damage and wear and tear, and repair work that can respond to such damage and wear and tear is required. Among them, KF Road Maintenance N is a particularly high-performance repair material.
