Advances in Civil Engineering, Volume 2026, Issue 1, 2026.With the growing need for sustainable building materials, the use of recycled materials in concrete production is encouraged. Reclaimed asphalt pavement (RAP) is a by‐product of road rehabilitation operations and is one possible substitute for natural aggregates (NAs) in concrete. In the case of RAP aggregates, however, the asphalt that has aged on the

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.This study investigated the suitability of natural cinder gravel blended with fine‐crushed aggregates as a base course pavement material using laboratory tests and numerical simulations. Laboratory test results for natural cinder gravel indicated that cinder gravel alone failed to meet the Ethiopian Roads Authority (ERA) standard specifications for ...

Rheo‐Chemical Characterization and ML‐Based Prediction of Rejuvenated RAP Binders
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Reclaimed asphalt pavement (RAP) has gained significant attention in pavement engineering due to its economic and environmental benefits. However, the high stiffness and brittleness of aged RAP binders (RPB) necessitate the use of rejuvenators to restore their performance. This study evaluated the effectiveness of two commercial rejuvenators (PX and RB)
