To test crack router machine working performance, which contains a comprehensive experimental and modeling investigation on the contraction and expansion of asphalt mixture due to thermal cycles. As part of this study, a model of crack router machine was developed for thermal stress analysis during cooling/heating cycles using different cooling rates and isothermal conditioning periods.
The model accounts for the asphalt mixture glass transition and physical hardening, and it can be used to investigate which thermo-volumetric parameters significantly affect the asphalt mixture response during cooling and heating cycles.
A new crack router machine model, which was developed and validated. This model represents a significant step forward in accurately quantifying the cracking mechanism in pavements.
