Abstract: The invention relates to a method for paving low-traffic roads or paths with a paving slab that is cast in situ and has a width Dx narrower than the smaller value of D1 and D2, wherein D1 is the free distance between the front wheels of a standard haulage truck and D2 is the distance separating the wheels of the rear-wheel train, being the length of the paving slab Lx shorter than the value of the length L of the free distance between the front axle and the first rear axle of the wheel train of the standard haulage truck, such that the dimensions Dx and Lx mean that a single wheel or, alternatively, a single wheel train of the standard truck is always supported by the paving slab, touching same.

Abstract: A steel bar with ribs to form concrete armours, which allows the concrete to be maintained on the elastic zone of its strength with a stress less than 50% of the damage stress, where such bar has a nominal diameter Dn; a distance between consecutive rib centers “L”; a rib height “h” and a rib area “A”, where such area “A” is greater than 0.12×P×L and less than 0.25×P×L. The height “h” is greater than 0.12×L and less than 0.25×L.

Abstract: A concrete slab where the maximum width value of the slab Dx is determined by the lower measure between the distance D1 of the front wheels of a model loading truck or by the mean, and the distance D2 of a rear running gear of the same truck or the mean; the maximum slab length L is determined by the distance between the truck axles or the mean; and the thickness E is determined by the concrete resistance value, in view of anticipated traffic loads, the kind and quality of the base, and the ground type. The design methodology of this concrete slab allows for only one wheel or only one running gear of the truck to touch and move over the slab.
