Abstract (en)
[origin: WO8505136A1] A roadway barrier section (10) includes a duct (26) formed of two intersecting frusto-conical portions (32, 34) placed end-to-end so that the portions taper from the ends of the barrier toward the central portion (40) thereof. The duct (26) is formed using two tapering mold plugs (76, 78) that are preferably frusto-conical. The mold plugs (76, 78) are placed in a concrete form so that the lower edge (30) of the duct (26) is a straight line that is generally parallel to the base of the barrier section (10).
