<p>In order to deposit in a speedy manner an even layer of sand reinforced with randomly mixed small mesh pieces of high flexural recovery (4), a tracked vehicle 1 is used. The vehicle has a hopper 3 for the reinforced matrix 4, from which the matrix 4 is fed by a feed conveyor 5 to a vertically reciprocating transverse blade 12; on each stroke, the blade 12 penetrates the top surface to push the mesh pieces down into the layer. The layer then passes down between parallel runs of two belts 9,10, is deposited from the lower belt 10 onto the soil, and is subsequently smoothed by a vibrating plate 11.</p> |
