Laboratory Evaluation of Cold Patching Asphalt Mixture with Refined–Processed Recycled Asphalt Pavement

Processes, Год журнала: 2025, Номер 13(3), С. 869 - 869

Опубликована: Март 15, 2025

This study investigates the effects of two separation processes: traditional technology (TST) and refined (RST), on characteristics recycled asphalt pavement (RAP) performance cold patching mixtures (CPAM). The research evaluates RAP efficiency, focusing content agglomeration degree, examines mechanical, high- low-temperature, moisture susceptibility, anti-stripping, fatigue CPAM with varying (0–75%). A key innovation this is exploration using RST-RAP for production in comparison to TST-RAP. findings reveal that RST process significantly enhances coarse aggregates from mortar, leading improved gradation, reduced agglomeration, better overall quality compared TST. Incorporating into Marshall stability, showing higher gains than TST-RAP, particularly at content. Additionally, dynamic low-temperature cracking resistance, life were positively influenced by RST-RAP, optimal achieved 25–50% In contrast, excessive content, especially negatively impacted mixture’s properties, brittleness stability. highlights novelty enhance performance, suggesting more effective improving performance. However, should be carefully controlled (25–50% ≤25% TST-RAP) meet technical standards ensure durability. These provide valuable insights optimizing utilization sustainable maintenance practices.

Evaluation of Regeneration Effects of Different Rejuvenators on Aged Asphalt

Buildings, Год журнала: 2025, Номер 15(7), С. 1171 - 1171

Опубликована: Апрель 2, 2025

As a polymer-like organic material, asphalt often undergoes aging during service life. Regeneration technology is the main approach to achieve its recycling; therefore, rejuvenator an important factor affecting regeneration effect. In order evaluate rejuvenation effects of rejuvenators on aged asphalt, fluid catalytic cracking (FCC) slurry and penetrant containing epoxy functional groups were used prepare conventional (CR1 CR2) penetrable (PR). The impact physical properties was investigated, different mild severe evaluated through rheological tests. Results show that effectively lubricates movement molecules, improving high temperature stability resistance rejuvenator. CR1 CR2 are more suitable for as has relatively minimal effect chemical composition colloidal structure asphalt. At 25% dosage, PR significantly restores while still fail meet specifications. effective because it not only dissolves disperses asphaltenes but also weakens interactions between asphaltenes, which facilitates restoration enhances findings this study provide insights into design efficient utilization reclaimed pavement (RAP).
