The invention concerns a compacted rolled fibre-reinforced concrete composition and a method for making continuous pavements and industrial areas without joints, the metal fibres consisting of wires (10) with a diameter (d) of 0.38 to 15 mm, a total length of 19 to 80 mm, a length (<i>l, l'</i>) of the curved end parts (12) of 1.5 to 4 mm, a transverse offset (h, h') of at least 0.75 mm, an obtuse angle ( alpha , alpha ') between each gap portion (13) and the central part (11), an obtuse angle between each gap portion and end portion, and a minimum tensile strength of 900 n/mm<2>, said composition comprising, per cubic metre of concrete, 180 to 400 kg of hydraulic binder, 90 to 150 litres of water, and 25 to 60 kg of fibres, and not more than 1.8 wt. % of plasticizer and/or retarder admixture. |
