Experimental Investigation of Strength, Microstructure, and Durability Behavior of Steel Fiber‐Reinforced Reclaimed Asphalt Pavement Concrete

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

Experimental Characterization and Numerical Performance Assessment of Treated Cinder Gravel for Base Course Applications

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 ...

Mix Proportion Optimisation Design and Performance Evaluation of a Cold‐Recycled Mixture Based on Uniform Design and Bailey Verification

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
To eliminate the gradation variability of reclaimed asphalt pavement (RAP) materials and improve the road performance of cold‐recycled mixtures, this study analyses the gradation variability of recycled materials and conducts gradation design using the actual particle sizes of extracted aged materials.

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)

Evaluation of the Performance of a Composite Material Made From Lateritic Soil, Crushed Granite, and Cement for Use as the Base Layer of Road Pavement

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The base layer is important for the road pavement structural performance. This study aims to monitor the performance of various local composite materials as road construction materials. To do this, an experimental study treated the improvement of geotechnical properties of a lateritic gravel, initially nonadopted as a base layer, by using three ...

A Unified MARS‐NRBO Model for Predicting Dynamic Modulus of Asphalt Concretes and Stone Matrix Asphalts Produced by Hot and Warm Technologies

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The dynamic modulus (|E∗|) is the key parameter to characterize the viscoelastic behavior of asphalt mixtures, making it an essential component of the mechanistic‐empirical pavement design guide (MEPDG). However, direct laboratory measurement of |E∗| is time‐consuming and costly, motivating the development of reliable predictive models.
