![]() Taking advantage of them for mechanistic calculations of road pavement may eventually lead to incorrect estimation of the remaining fatigue life and then inadequate selection of pavement reinforcement. Deflection basins with small differences of displacement values may correspond to significantly different combinations of material parameters. Among the factors that impact on the quality of results is the accuracy of deflection measurement. ![]() ![]() Measured values allow to determine the material parameters of the road structure, corresponding to the obtained results, by means of backcalculations. ![]() Deflections of road pavement under a known load are most commonly measured in such tests, e.g., with the use of falling weight deflectometer (FWD). Nondestructive tests of road pavements are among the most widely used methods of pavement condition diagnostics. ![]()
