As a solid waste, graphite tailings (GTs) have caused serious harm to the environment and nearby residents, using GTs as pavement materials can not only solve environmental problems but also promote sustainable pavements. To this end, study experimentally explored feasibility of three kinds (named GT-A, GT-H, GT-W) fillers prepare asphalt mastics analysed their micro properties, mechanical asphalt-filler interaction, dielectric properties. The results show that (GTAMs) less bee-like...
The interaction between bitumen colloidal and mineral aggregate is complicated owing to an intricate interplay of chemistry, mineralogy, surface topography. Identifying the adsorption configuration bitumen-aggregate interface has been a longstanding challenge in science material engineering. In this paper, we report mechanistic study using molecular dynamics simulation uncover at scale how mineralogy affects it. results show that adsorbed layer densely distributed compared bulk bitumen, its...
To decrease the usage of petroleum asphalt and improve waste recovery, two different groups recycled oils were selected to low-temperature performance binders in cold region. The multiple stress creeps recovery (MSCR) test, linear amplitude sweep (LAS) test bending beam rheometer (BBR) performed evaluate rheological properties oil modified (ROMA). thermal double edge notched tension (DENT) tests employed characterise cracking resistance ductile ROMA, respectively. results this study showed...
The warm mix asphalt (WMA) technology is commonly applied for highway pavements in high-altitude plateau regions China, where extreme weather conditions are common. study to evaluate the performance of WMA with different additives areas. tests show that all could reduce viscosity binder mixing and compacting temperature mixture. solid also decrease penetration ductility value, increase softening point PG high binder; therefore, suitable improving high-temperature regions. However,...
Asphalt mastic is a binary composite in which the bitumen matrix embedded with filler particles. By taking interparticle interactions and effects of origins types into account, this research seeks to achieve higher predictive precision modulus asphalt mastics using micromechanical models. To goal, five classical models Ju-Chen model (JCM) that effectively considers were adopted predict moduli 25 kinds composed types. The results show prediction accuracy general self-consistent (GSCM) highest...
