ABSTRACT:
A prefabricated road median walls are mounted along a median line of a road to divide the road into two sections according to the direction of vehicles traveling on the road. The prefabricated road median wall includes a plurality of unit blocks manufactured by mixing rubber powder with a fire retardant material at a predetermined ratio and conducting a compression molding process. The unit blocks are stacked sequentially, with a plurality of support holes vertically formed through each of the plurality of unit blocks, so that the support holes of the unit blocks communicate with each other. The prefabricated road median wall further includes a locking means to couple the stacked unit blocks together, thus forming a median wall body; and a plurality of anchor posts. Each anchor post is embedded at a lower part thereof in the ground while a remaining part of the anchor post is exposed to the outside, so that the exposed part of the anchor post is inserted into each of the plurality of support holes of the median wall body, thus supporting the median wall body on the road.
