ABSTRACT:
The road-guard construction comprises a first wall of superimposed whole tires disposed horizontally in vertical rows and horizontal columns. A second wall of superimposed half tires--which are cut circumferentially along their tread path, is also disposed in vertical rows and horizontal columns. Each half-tire defines a toroidal chamber, facing upwardly. Tie-bands interconnect the whole tires to the half-tires, whereby a single integral wall unit is achieved. Sand is poured into the toroidal chambers of the half-tires, whereby the first and second walls become firmly anchored to the ground. The road-guard will therefore remain substantially immobile over ground even after repeated vehicle impacts.
