Numerical investigation on fracture evolution of asphalt mixture compared with acoustic emission

International Journal of Pavement Engineering, 2021
To reveal the fracture damage of asphalt mixture, an image-based numerical approach is proposed in this study considering the distribution of aggregate and asphalt mortar. Both digital image processing technique and discrete element method are applied to

Waste Aggregates in Asphalt Mixtures

2023
Abstract: As part of the RILEM Technical Committee TC 279-WMR on valorisation of waste and secondary materials for roads, Task Group 3 used various waste aggregates as a replacement for natural aggregates in asphalt mixtures, namely, construction and demolition waste, recycled concrete aggregates and steel slag.

Cooling asphalt pavement by increasing thermal conductivity of steel fiber asphalt mixture

, 2021
High-temperature asphalt pavements will intensify urban heat island effect and cause many pavement distresses. In order to cool asphalt pavement, two types of steel fiber, curved hook steel fiber (CH-SF) and long sawtooth steel fiber (LS-SF), were used ...
