Abstract
Pavement using porous concrete is expected to be a promising technique with high drainage capability and low-tire/road noise property, because of its high porosity. In case porous concrete is applied to a rehabilitation technique of an existing pavement, thin bonded overlay on both ordinary jointed concrete pavements and asphalt pavements is thought to be a practical method, because most of the rehabilitation job does not allow the high raise of formation. In this technique, the bonding is the important key to success; therefore fundamental experiments and the following fields test regarding bonding were executed. In conclusions, bonding can be got through a suitable selection of bonding material and an adoption of appropriate surface treatments on the existing layer. In addition, full-depth porous concrete construction method is applicable to the thin bonded rehabilitation only with applying the bonding material in advance.
