By adjusting the thickness of the upper roadbed 2b formed in the second step according to the value of degree of compaction of lower roadbed 2a (Kvalue in plate loading test), which is obtained after the first step to prevent any local deformation (for example, cracks) on the surface layer 3 of the paved road 10 due to the weight.SELECTED DRAWING: Figure 1
