A comparative study was conducted to determine the effects of graphene and carbon nanotubes on thermo-mechanical properties asphalt binder using molecular simulations experiments. Micro-morphology measured by scanning electron microscopy. Thermal stability glass transition temperature were investigated differential calorimeter. Simulation results indicated that Tg had slightly changed for graphene-modified (GMA) nanotubes-modified (CNsMA) thermal expansion coefficients conductivity increased...
To decrease the usage of energy and improve waste recovery, dynamic simulations are conducted to understand diffusion mechanism rheological properties bio-oil regenerated asphalt. A new simplified model modified asphalt (BMA) is built calculate coefficients, driving force, viscosity, solubility parameters, ductility. The calculated coefficients bio-oil, asphaltenes, saturates, resins 4.5×10−3 cm2/s, 3.6×10−4 4.2×10−4 5.1×10−4 cm2/s at 298 K, respectively. Results indicate that diffuses...
This study compared the feasibility of circulating fluidized bed boiler fly ash (CFBFA), pulverized coal furnace (PCFA), and gasification slag (CGS) for preparation geopolymers by investigating Si Al dissolution reaction raw materials, product structure, development mechanical properties geopolymers. The results indicated that mechanism preparing were same three kinds based ash, i.e., depolymerization repolymerization Si-O Al-O bonds in materials. loose porous microstructure CFBFA resulted a...
Aged asphalt mixture is heavily involved in pavement maintenance and renewed construction because of the development recycling techniques. The aged bitumen binder has partially lost its viscous behavior. Rejuvenators are therefore designed used this procedure to enhance behavior such reclaimed bitumen. However, tests have not yet been clearly specified understand diffusion characteristics rejuvenators In research, molecular dynamic simulation proposed conducted with Materials Studio software...
This paper focuses on the life cycle assessment (LCA) of different types biochar modified bioasphalt (BMBA) by considering greenhouse gas (GHG) emission and environmental pollution factors. Biochar bio-oil were obtained from two biomass (waste wood pig manure). The application BMBA would not only improve efficiency utilization but also enhance protection. Analyses carried out stages which stem combination material preparation, construction, use, maintenance, demolition recovery. GHG (CO2...
