文摘

Measure the viscosity, light absorbance, thermal conductivity of graphite modified asphalt binder. Capture the infrared image of samples during healing process to study the temperature distribution. Analyze the displacements of sample particles during cyclic light healing processes by digital image correlation. Evaluate the healing capacity of graphite modified asphalt mixture beams by fracture-light healing tests.
