Energy conservation and carbon emission reduction of cold recycled petroleum asphalt concrete pavement with cement-stabilized phosphogypsum

Construction and Building Materials, Год журнала: 2024, Номер 433, С. 136696 - 136696

Опубликована: Май 23, 2024

Phosphogypsum, a byproduct generated during the production of chemical fertilizers, can pose significant environmental threat when not managed appropriately. This study endeavors to explore potential repurposing phosphogypsum by incorporating it into cement-stabilized base asphalt concrete pavement. We conducted an in-depth optimized scheme using specific engineering project as case study. substitutes for part cement in original base, creating mixed material (CSPM) road construction. The primary aim is assess energy consumption, carbon emissions, and implications throughout various construction phases within life cycle assessment (LCA). Additionally, sensitivity analysis scrutinize influence underlying layer, layer thickness transport distance on consumption emissions. results indicate noteworthy reduction, showing 42.5% decrease 12.7% Moreover, crushed stone (CS) milling planer (MPM) have greatest impact transportation stage. Notably, phase yields most substantial benefits, demonstrating 48.0% 67.5% facilitates reuse reclaimed pavement (RAP) materials phosphogypsum, resulting 44.3% reduction mineral usage, 6.9% petroleum asphalt, preventing 16.859 square meters waste occupancy.

Preparation and Performance Characterization of Phosphogypsum Whisker Composite Modified Asphalt Binder

Journal of Materials in Civil Engineering, Год журнала: 2024, Номер 36(7)

Опубликована: Апрель 23, 2024

Solid waste recycling and reuse have attracted great interest as environmentally friendly modifiers for asphalt pavements in recent years, phosphogypsum whiskers (PSWs) synthesized by (PSP) wastes were used the main modifying material to develop an binder this study. PSWs could significantly enhance deformation resistance fatigue performance of but prone cracking at low temperature. To alleviate problem, novel idea developing a PSW composite modified was proposed The organic coating method surface modify using surfactants ultrasonic vibrator compatibility with binder. Then modifier containing (MPSW) developed uniform design (UDM), preparation process investigated response (RSM) on basis. physical conventional tests; high-temperature performance, rutting resistance, several rheological low-temperature evaluated force ductility test (FDT). microstructure modification mechanism characterized Fourier transform infrared spectroscopy (FTIR) differential scanning calorimetry (DSC) test. results showed that self-developed (MPGJ-I) effectively reduce negative effects MPSW properties, it exhibited significant aging compared other commonly modifiers. In addition, enhancement performance. MPGJ-I not only solved adverse effect also enhanced certain degree. physically mixed did change its chemical structure. reduced influence glass transition temperature (Tg) improved thermodynamic properties temperatures. comparison study revealed comprehensively service virgin binder, recommended dosage 6%.
