concrete cover slabs improved to streets, roads and highways, and methodology for the design of the slabs.

摘要

the traditional work systems used up to now consider a slab width equal to the width of the cover, and a length equal to the lane width of the lane, or 6 feet.these are the charges of vehicles, in particular to a loaded truck, is applied on the both sides at the same time, resulting in tensile stresses on the surfaces of the tiles are tiles go nuts.the present invention proposes to construct a concrete slab in which the maximum value of the width of the slab, as is given by the distance d1 of the lower of the front wheels of a truck loading model or the average.and the distance d2 of the rear body of truck tread or the average and maximum length l of the slab is given by the distance between the axles of the truck or the average; and the thickness is given by the value of concrete strength as a function of the traffic intensity. the type and quality of the base and the type of soil.the present invention includes the design method of the concrete slab, which is still only a single wheel or a rolling body of the truck, the truck is used as a model or the medium is in contact with the slab and moving on.
