<p>The invention refers to a roadway (1), by which in each critical area (10) adjacent to the transition between two adjacent opposite curvatures, where the top surface of said roadway (1) is normally horizontal or at least approximately horizontal, efficient draining of the surface water may be achieved, and at the same time also the roadway is capable to withstand the destruction due to meteorological impacts or also due to usual traffic loadings. Such roadway (1) is furnished, on each side of said critical area (10) having zero-inclination in the transversal direction, with at least one sequence (2, 3) of groups (20, 30) of grooves (200, 300), which are arranged on the top surface (11) of the roadway (1) and extend in an inclined direction with respect to either a driving direction (N) or each belonging border (12, 13), by which said groups (20, 30) of grooves (200, 300) extend parallel to each other i.e. under the same inclination with respect to each corresponding border (12, 13) of the roadway, and wherein each particular groove (200; 201, 202, 202, 203, 204, 205, 206, 207; 300; 301, 302, 302, 303, 304, 305, 306, 307) in each particular group (20, 30) of grooves (200, 300) is completely coated on its internal surfaces with a layer (201', 202', 202', 203', 204', 205', 206', 207'; 301', 302', 302', 303', 304', 305', 306', 307') of a hydrophobic coating.</p> |
