The tough shut-off drainage tape is a drainage tape designed to promote the drainage of rainwater that has penetrated the pavement of road bridges, preventing water from accumulating on the waterproof layer, which can lead to reduced pavement adhesion and cause potholes or damage.

After construction, black tire marks are often seen outside the construction area. This is due to the construction machinery pulling the tack coat outside the designated area. The purpose of the tack coat work is to enhance the adhesion between the layer of the mixture being laid and the underlying layer. If the tack coat that has been sprayed gets attached to the tires of the construction machinery and becomes disturbed from the sprayed surface, there is a concern that the interlayer adhesion will decrease. To solve these problems and improve the reliability of the tack coat, "Tack Fine E" has been developed. "Tack Fine E" is a special modified asphalt emulsion (JEAAS PKM-T) designed to minimize the adhesion of the tack coat to the tires of the construction machinery, thereby fully realizing the original effects of the tack coat.

The RC joint seal L-shaped is a tape-like molded joint material blended with thermoplastic elastomers and rubber in a special asphalt. By creating grooves in the tape, it is molded to facilitate the formation of an L-shape. It exhibits water-stopping effects even in areas prone to water accumulation, such as bridge ends, and helps prevent water infiltration into the surface of the floor slab.

Waterproof drainage pavement (POSMAC) is a technology for constructing drainage pavements. 【Features】 ○ Using an asphalt finisher equipped with an emulsion spraying device (SPAF), high-concentration modified asphalt emulsion (cationic GS-C) is sprayed in large quantities and uniformly while simultaneously laying the drainage mixture, forming a waterproof layer beneath the drainage mixture layer to protect the base surface from infiltrating rainwater and other sources. ○ By utilizing this method, the reliability of the pavement is enhanced by protecting the base surface compared to conventional drainage pavements that are constructed in a single layer. ○ It allows for significant cost reduction compared to drainage pavements constructed in two layers, including the base layer. ○ The filling of asphalt contributes to stress relief effects, which is expected to suppress reflection cracking. ● For other functions and details, please download the catalog.
