The PRMS (Pavement Resistance Management System) 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. The color of the aggregates includes standard colors such as brown, yellow, blue, white, and green, in addition to black, allowing for road surface colorization.

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 a highly durable high-performance epoxy resin with fine aggregates of special particle sizes. The permeable resin mortar is filled in a wedge shape into the depressions of the permeable pavement (porous asphalt pavement), which is effective for reinforcing the surface of the permeable pavement. Additionally, the surface after filling has improved 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 color customization of the road surface.

The "PRMS (Palms) multifunctional construction method" is a technique that fills the voids in the surface aggregate of 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). The coating optimizes the elasticity of the recycled tire chips and improves adhesion with the urethane resin binder, significantly enhancing the durability of the elastic resin mortar. Additionally, the durability of functions such as preventing clogging of the voids in drainage paint has been improved. For more details, please contact us or download the catalog.

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 reinforces the surface of permeable pavement and aims to maintain and extend its functionality but also allows for repairs, thereby further enhancing the lifespan of this valuable infrastructure. Additionally, it is expected to achieve a high level of noise reduction.
