Abstract: In article the offered optimizing models of calculation of a design of nonrigid road clothes constructed taking into account the requirements provided in ODN 218.046-01 are considered. Two methods for the solution of a problem of selection of a design of nonrigid road clothes, optimum at cost, are offered: a method selection of a design by a variation of thickness of constructive layers and a design trial and error method by a variation of materials of constructive layers. Application of genetic algorithms for the solution of an optimizing problem of calculation of a design of nonrigid road clothes on the basis of comparison of their efficiency with efficiency of gradient and reboric methods is proved. Besides, genetic algorithms allow at the solution of such tasks to consider both linear and nonlinear restrictions. The technique and results of digitization and submission of the nomograms and schedules used for calculation of a design of nonrigid road clothes according to ODN 218.046-01 in the form of auxiliary tables and systems of the equations received by means of a method of the smallest squares are given.
