透水性レジンモルタルシステム工法協議会 List of Products and Services

The PRMS (Palm's) grip method is a traffic safety measure that aims to improve skid resistance performance by overlaying a thin layer of permeable resin mortar on existing drainage pavement (porous asphalt pavement) where skid resistance has decreased. Since fine aggregates are laid on the road surface, it is possible to grip the tires and reduce slip accidents. In addition to black, the aggregate colors include standard colors such as brown, yellow, blue, white, and green, allowing for road surface coloring.

• Special Construction Method

The PRMS method involves filling the voids (depressions) on the surface of permeable pavement (porous asphalt pavement) with a permeable resin mortar made by mixing high-performance epoxy resin, which is highly durable, with specially sized fine aggregates. The permeable resin mortar is filled in a wedge shape into the depressions of the permeable pavement (porous asphalt pavement), which effectively enhances the surface strength of the permeable pavement. Additionally, the surface after filling improves noise reduction and slip resistance compared to a smooth permeable pavement (porous asphalt pavement). The color of the aggregates includes standard colors such as brown, yellow, blue, white, and green, in addition to black, allowing for colorization of the road surface.

• Mortar and plaster materials

The "PRMS (Palms) Multi-functional Construction Method" is a technique that fills the voids of the surface aggregate in drainage paint with elastic resin mortar. It uses special elastic aggregate (product name "PRMS Elastic Aggregate") and special urethane resin as filling materials, offering excellent durability, freeze prevention effects in snowy cold regions, and further noise reduction compared to drainage pavement. The "PRMS Elastic Aggregate" is made from recycled tires that have been chipped and coated with inorganic powder and resin, resulting in granules (approximately 1mm to 2mm) that optimize the elasticity of the recycled tire chips through coating, enhancing their adhesion to the urethane resin binder and significantly improving the durability of the elastic resin mortar. Additionally, the durability of functions such as preventing clogging of the voids in drainage paint has been enhanced. For more details, please contact us or download the catalog.

• Mortar and plaster materials

The permeable resin mortar filling method (PRMS method) is a technique that involves mixing a high-performance resin binder with special particle-sized fine aggregates to create a permeable resin mortar mixture, which is then filled into the gaps between the surface aggregates of permeable pavement. This method not only strengthens the surface of permeable pavement and helps maintain and extend its functionality but also allows for repairs, further enhancing the lifespan of this valuable infrastructure while also achieving a high level of noise reduction.
