Improved concrete pavement slabs for streets, roads or highways and the methodology for the slab design

摘要

The traditional paving systems employed until now, consider the width of pavementslabs equal to a lane width and the long dimension equal to the lane width or 6 meterslong. These dimensions make that the vehicles loads, and especially loaded truck,apply the loads at both edges simultaneously, inducing tensile stresses on theslabs surfaces when they are warped. The current invention proposes to builta concrete slab where the maximum width value of slab Dx is being given by the lowermeasure between the distance D1 of the front wheels of a model loading truck orby de mean, and the distance D2 of a rear running gear of the same truck or the mean;the maximum slab length L is given by the distance between the truck axles or themean; and the thickness E is given by the concrete resistance value, consideringtraffic loads, the kind and quality of the base, and the ground type. The currentinvention comprises the design methodology of this concrete slab, which allowsthat always only one wheel or only one running gear of the truck, used as model truckor mean, touch and moves over the slab.
