  • Patent number: 12460357
    Abstract: A pavement system that avoids the need for traditional contraction joints regardless of dimension of the pavement. The concrete composite pavement, comprises (i) a gap-graded concrete first layer; (ii) a flexural-hardening fiber reinforced mortar second layer, wherein the gap-graded concrete comprises cement, water and coarse aggregate, the flexural-hardening fiber reinforced mortar comprises cement; water, fine aggregate with a maximum particle size; fiber reinforcement comprising of synthetic and/or metal fibers; wherein the total thickness of the composite pavement is selected depending on the required maximum service point load, using the following formula H=(F/100)0.5×100 mm, where H is the total thickness of the composite pavement and F is maximum service point load; wherein the ratio of the thickness of flexural-hardening fiber reinforced mortar second layer to the total thickness of the composite pavement is within the range of 1:5 to 2:5.
