Combining Strain Measurement and FEM Simulation to Obtain Dynamic Response of Asphalt Pavement
並列摘要
Obtaining asphalt pavement strain response plays an important role in understanding pavement damage mechanisms in structural design and in predicting the life of the pavement. Combining strain measurement and finite element simulation is crucial to identifying whether or not the measured strain reflects the actual mechanical state. Therefore, the viscoelastic characteristics of asphalt mixtures were obtained first using a dynamic modulus test. Then, a small-scale laboratory loading test was developed according to the similarity theory with Fiber Bragg Grating (FBG) sensors embedded. Studies were then carried out to validate the measured strains in conjunction with a finite element method (FEM) model using the same conditions as in ABAQUS software. Finally, a brief description of the on-site instrumentation was introduced, followed by a preliminary analysis of typical three directional strain responses.
