Abstract:

PCT No. PCT/SE81/00159 Sec. 371 Date Jan. 25, 1982 Sec. 102(e) Date Jan. 25, 1982 PCT Filed Jun. 2, 1981 PCT Pub. No. WO81/03513 PCT Pub. Date Dec. 10, 1981.A method to distribute wear from passing vehicles to a road surface, according to which individual marks (3, 3', 4, 4', 5, 5') are applied to the road surface of each lane (1, 1') spaced apart from each other and extending in the direction of the road. The marks are applied in a side-by-side related distance that mainly corresponds to the width of each lane (1, 1'), and located in the lanes (1, 1') in such a way, that vehicles travelling in the lanes (1, 1') and passing over the marks (3, 3+40, 4, 4', 5, 5') with the wheels adjacent to the marks (3, 3+40, 4, 4', 5, 5') maintain the normal distance between each other corresponding to vehicles travelling in the center of the lanes (1, 1'). When the marks (3, 3', 4, 4', 5, 5') are mainly removed, due to the wear from vehicles passing over the marks (3, 3', 4, 4', 5, 5'), a new set of marks (3, 3', 4, 4', 5, 5') are applied, moved slightly sideways in relation to the marks (3, 3', 4, 4', 5, 5') first applied. Said marks (3, 3', 4, 4', 5, 5') are preferably painted to the road surface in a different color to conventional road marking lines, and also preferably including a symbol, such as a device mark or similar. By repeating the above described operation, the vehicles are successively moved from one side of the road towards the other side, thus distributing the wear imposed to the road mainly over the entire road surface. Each lane, (1, 1') may also be arranged with two lines of spaced marks (3, 3', 4, 4', 5, 5') at an internal distance mainly corresponding to the wheel-base of commonly used types of vehicles, in which case the drivers try to locate the vehicles in relation to the marks (3, 3', 4, 4', 5, 5') in such a way, that all wheels pass over the applied marks (3, 3', 4, 4', 5, 5').
