Bitumen (High Performance Asphalt)

This is a premium, workability-improving polymer-modified asphalt type II that uses a proprietary polymer dispersion control formula.
It is also possible to use it at a lower mixing temperature, which reduces the fuel and CO₂ required to manufacture asphalt mixture and shortens curing time, making it possible to open the road to traffic earlier.
It has been widely adopted on highways and at airports.

This asphalt is used to reuse old paving materials generated during repair work.
The generated material is collected, crushed, and classified to become recycled aggregate, but old asphalt still adheres to the surface of the recycled aggregate. Old asphalt has been oxidized and its composition has changed due to UV rays and rainwater over the years, making it hard and brittle, so it is necessary to adjust it to the original hardness of asphalt.
Reprophalt 300 blends well with old asphalt using a chemical approach, giving it an excellent finish on paved surfaces and edges, reducing stone chips and cracks. In the manufacturing process, it is possible to reduce waste mix material after storage in silos and increase the proportion of recycled aggregate while maintaining quality, improving the recycling rate of pavement.

This regeneration Asphalt rejuvenator prioritizes extending the life of pavements using recycled mixtures, and is compatible with restoring the composition of asphalt and allowing it to be handled at room temperature.
The finish of the recycled pavement is improved by restoring the asphalt components attached to recycled aggregate, whose composition has changed over the long term of use, to their original composition.
Since it is fluid at room temperature, it does not require heating during production and is easy to handle.

This is Asphalt rejuvenator that uses aromatics as its main ingredient and is developed using our unique technology, with the aim of extending the life of pavement using recycled materials as a top priority.
The waste materials are collected, crushed, and classified to become recycled aggregate, but the old asphalt still remains on the surface of the recycled aggregate. The old asphalt oxidizes and changes in composition due to years of exposure to ultraviolet rays and rainwater, and in particular the aromatic content, which is the main component, decreases, causing it to harden, lose adhesion, and become brittle. In order to recycle pavement waste, it is necessary to add recycling additives to the recycled aggregate with the old asphalt, which has become hard and brittle, to restore the asphalt's original hardness and components, and the finish and lifespan of pavement made with recycled materials will vary depending on the selection of recycling additives.
Approximately 70% of the main component of Reprovital 500 is aromatics. It replenishes lost components and restores the original quality of old asphalt.

We provide pavements that harmonize with any landscape, from tourist spots and historic cityscapes to futuristic buildings. While maintaining the same pavement quality, we have significantly improved workability and workability, and reduced the "odor'' generated during mixing and construction.
Based on the latest technology and know-how cultivated over many years, we deliver peace of mind to everyone who walks on the road.

This is a product manufactured only by our company in Japan.
This asphalt is made harder than straight asphalt by blowing air into molten petroleum asphalt. By changing its properties, it is easier to handle as an industrial product. As a waterproof material, it can be used as a raw material for roof vibration damping sheets, vibration isolating sheets for automobiles, and protective materials for submarine cables.
