1. A jointless concrete composite pavement, comprising:
(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 with particles size from 4 to 45 mm;
the flexural-hardening fiber reinforced mortar comprises cement, expansive concrete additive, water, fine aggregate with a maximum particle size of not greater than 8 mm; fiber reinforcement comprising of synthetic and/or metal fibers having diameter of 10 to 500 microns and length of 3 to 35 mm; 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.
