Cement concrete pavement thickness of the number of appropriate?
As the edges and corners of the board are most susceptible to damage, edge bars and corner bars (Figure 1) can be reinforced or made thick side sections, starting at 1 meter from the shoulder and increasing the thickness to the edge of the plate Thickness is 25% larger than the middle. In the highway and a highway, can be made from the inside to the outer edge of the gradual increase in the trapezoidal section. Most of the pavement panels made of single-layer; when the plate can also be made thicker double-layer, the upper thickness of not less than 6 to 7 cm. The lower layer of the use of poor quality materials made of low-strength concrete; in order to make the upper and lower layers of solid, the lower surface should be clean, rough and set the groove.
Most of the concrete pavement made of equal thickness section, thick 20 to 25 cm.
