| Abstract: | The researches on backcalculation methods of pavement layer moduli in China and other countries were reviewed. The advantages and disadvantages of 5 kinds of backcalculation methods, nomographies and regressive equations,iterative methods, database searching techniques, genetic algorithms and artificial neural networks, were discussed. It is pointed out that initial value and local convergency, uniqueness of solution, and reasonableness of backcalculation results are the 3 key issues.1 tab, 10 refs. |
