摘要： PROBLEM TO BE SOLVED: To reduce soil improvement works to the minimum by disposing a concrete slab on a roadbed with its convex or concave surface arranged on the roadbed side, and laying the concrete slab such that at least part of the convex or concave surface side cuts into the roadbed. SOLUTION: A concrete slab 10 is produced by arranging forms 14 on a flat upper surface of a stand 16, arranging at least one reinforcement or steel frame in each form 14, placing ready mixed-concrete 18 in the form 14, forming an upper surface of the ready mixed-concrete 18 into a convex surface 12, and thereafter curing the ready mixed-concrete 18. The concrete slab 10 is disposed with its convex surface 12 arranged on a roadbed side, and laid such that at least part of the convex surface 12 side of the concrete slab 10 cuts into the roadbed. Thus, the concrete slab 10 exerts reinforcing effect with respect to the ground, and a load is dispersed and smoothly transferred. As a result, an effect which is similar to one exhibited by the soil improvement of the construction site and the vicinity thereof can be exerted, and therefore soil improvement works can be drastically reduced.
