Combining Strain Measurement and FEM Simulation to Obtain Dynamic Response of Asphalt Pavement

In predicting the life of asphalt pavement and in understanding asphalt pavement damage mechanisms in structural design, an important role is played by obtaining asphalt pavement strain response. To identify whether or not the actual mechanical state is reflected in the measured strain, it is crucial to combine strain measurement and finite element simulation. A dynamic modulus test was therefore used to first obtain the viscoelastic characteristics of asphalt mixtures. The similarity theory with embedded Fiber Bragg Grating (FBG) sensors was used to develop a small-scale laboratory loading test. Using the same conditions as in ABACUS software, studies were then carried out for measured strain validation in conjunction with a finite element method model. Finally, there was introduction of a brief description of the on-site instrumentation, followed by a typical three direction strain response preliminary analysis.
