The Drainage Pavement (Low Noise Pavement)
The drainage pavement provides with the basic function such as traveling safety for road vehicles in rain due to high drainage capability and noise reduction by installing the porous asphalt mixture layer with large air-void.
Kajima’s drainage pavement series is classified into 3 types: 1)Standard type drainage pavement, 2)Resin coated drainage pavement, 3)Colorized drainage pavement.
Furthermore, in case the function is lowered after the road is put into service, Kajima can provide Kajima vehicle for drainage function recovery, which enables to eliminate the void blocking substances thereby rehabilitating the lowered function.
