Claims12
A protective roadway barrier adapted for assembly on a roadway by the interlocking of a plurality of base members in end-abutting relationship comprising
- (a) a plurality of base members, each of said base members having an elongate horizontal length and a generally inverted C-shaped cross-section wherein the bottom of said base member is substantially wider than the top of said base member and in a position elevate above the roadway, the surface of said base member formed of at least two plane sections having partial triangular cross-sections;
- and
- (b) a pillar adapted for interlocking coupling between two of said base members, said pillar projecting above the top of said base members;
- and
- (c) at least one elongate steel barrier plate, and means for connecting said barrier plate to said pillar at a position elevate above said base member.

A prefabricated road barrier section adapted for end-abutting interconnection to a plurality of similar sections for assembly on a roadway and for carrying elevated and elongated deflection steel plates, comprising
- (a) a base member having vertical ends and having a cross-section shape formed by the joining together of four plane shapes, comprising:
- (1) a first and lower shape having steep-sided walls symmetrically to the vertical;
- (2) a second and intermediate triangular shape having walls symmetrically aligned at an angle of approximately 45.degree. relative to the horizontal;
- (3) a third and upper triangular shape having steep-sided walls symmetrically aligned at an angle exceeding 45.degree. relative to the horizontal;
- and
- (4) a fourth shape being parallel to the roadway;
- (b) at least one spacer interconnected between opposite walls of said base member;
- (c) a pillar adapted for connection to at least said fourth shape, said pillar carrying at least one steel barrier plate at a position elevated above said base member.
