Structural beam for crack repair

A reinforcing beam adapted for embedment in a road material for bridging an underlying crack therein, said beam comprising:

• a body of compression resistant material presenting a top surface, a bottom surface and first and second opposed ends, said bottom surface at said body first end adapted to be positioned on a first side of the underlying crack with said bottom surface at said body second end adapted to be positioned on an opposed second side of the crack;
• a plurality of spaced apart serrations projecting from said first end, said serrations presenting a surface adapted to contact the surrounding road material in relative movement therebetween upon forces acting on the body whereby to present a joint spanning the crack;
• means at said first end of said body for forming an area for a controlled subsequent cracking of the road surface.

• and
• a shelf projecting from said body first end, said shelf presenting a projecting surface adapted to contact the surrounding road material in relative movement therebetween upon forces acting on the body whereby to present a joint spanning the crack.
