<p>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. 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. The length of the paving slab Lx is 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. The method comprises the steps of: providing for paving either a low-traffic road which has neither asphalt or concrete paving, or a low-traffic path; evening out and levelling the road or path to be paved; determining the width and length of the paving slab and establishing the thickness thereof in accordance with the amount of traffic and the traffic load, the bearing capacity of the natural ground, the strength of the concrete, the residual strength thereof and the climate, such that the thickness is between 5 and 15 cm; determining the amount of fibre required for a required design residual strength of between 10% and 50% of the maximum strength of the concrete; and preparing the mixture of concrete and fibres which are selected from steel, glass, polypropylene, carbon or another structural fibre for concrete. In addition, the method comprises pouring the mixture of fibre concrete directly onto the road or path to be paved according to the size of a dimensioned paving section, or pouring the mixture of fibre concrete directly onto the road or path to be paved. The invention also relates to a concrete slab for paving low-traffic roads or paths and to a method for producing same.</p> |
