Porous Asphalt Pavement is the pavement where porous asphalt mixture having continuous porosity is used for the surface course. It is applied to permeable pavement and drainage pavement as well as low noise pavement taking advantage of its porosity.
Topcoat for porous asphalt pavement prevents the pavement from air void choking, clogging and aggregate scattering by the resin coating which is formed by spraying special resin onto the pavement. It keeps the features of porous asphalt pavement for a long time.
Solar radiation reflective pavement is the pavement on which the surface is coated with solar radiation reflective paint. It constrains the rise of road surface temperature by reflecting near infrared rays of the sunshine which are also called heat-rays.
Water retaining pavement is the pavement using porous asphalt mixture
of which the void is filled with water retaining material. The heat of
vaporization by its retained water restrains the rise of pavement temperature
due to solar heat. It can contribute to a mitigation of heat-island phenomena
Porous Pavement Cleaning Machine is designed to clear the clogging of porous pavement using water jet followed by the suction of dirt water in order to prevent the pavement from decreasing in its function.
