The invention relates to a paving or revetment (1) comprising a top surface, such as a wearing course or a dike revetment, and a conveying element (3, 4, 6, 7, 8, 9) for conveying a liquid, such as water, along the top surface and for the transfer of heat between the top surface and the liquid. The paving (1) is characterized in that it comprises a top layer (5) with a porous layer (4) beneath which has at least 20% voids. A closed sealing layer (3) is placed beneath the porous layer (4). The liquid conveying element (3, 4, 6, 7, 8, 9) comprises in the longitudinal direction a discharge element (7, 8) and a supply element (6, 9), both of which connect to the porous layer (4) for the conveyance of liquid through said layer (4). The paving (1) according to the present invention forms a cheap solar collector which is entirely composed of materials which are in standard use in roadbuilding for paving roads. The system is relatively efficient, is easily overlaid and can be reused during replacement, renovation and other alterations of the top surface. |
