Novel Sustainable Pavement Material: Recycling of Waste Shells as the Filler of Asphalt Mastic

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер 12(35), С. 13048 - 13061

High-quality limestone, as a nonrenewable resource, is decreasing with the maintenance and construction of asphalt pavements. Meanwhile, due to growth shell farming industry, great amount waste shells produced annually, which are mainly disposed in manner stacking, landfill, or discarding into sea directly, leading serious environmental pollution. This research used mussel, pectinid, oncomelania, oyster raw materials prepare four fillers, aiming at substituting mineral resources recycling same time. The mastics were prepared by mixing base SBS-modified fillers under different filler-asphalt ratios, respectively, limestone adopted control groups. physical rheological properties five evaluated, chemical composition microstructure measured investigate acting mechanism between asphalt. Results indicate that have lower density, hydrophilicity coefficient, higher specific surface area than exhibiting better compatibility For properties, both modified mastics, pectinid exhibit lowest penetration phase angle, while their complex modulus softening point highest among types indicating antideformation ability. Moreover, increasing ratio, ability mastic increases gradually, exhibits more behavior. In addition, analysis results demonstrate looser structure attributed interlaced layered aragonite calcite, larger contact Besides, there some organic matter present shell, plays role like modification, improving presence show synergistic effect road performance mastic. work verifies feasibility replace conventional beneficial recycle reduce consumption resources.

Clarifying the action mechanism of steel slag and waste tire crumb rubber in asphalt mixtures is great significance realising solid resourcing improving road quality. This study focused on adhesion behaviour mixture from mixing to application explored SBS/crumb composite modified (SBS/CR CMA) multiple scales. The results show that SBS/CR CMA exhibit excellent properties during application, electrostatic force plays a leading role whole process. contribution 3CaO·SiO2 > 2CaO·SiO2. Among them, strong interaction between CR main improve property CMA. can slow down flow water molecules its surface, improves damage resistance slag-SBS /CR significantly. Selective occurs when mixed with different aggregates, object depends initial work aggregates.
