Multiscale assessment of asphalt emulsion as a toughening modifier for self-compacting concrete: Mechanical behaviour, microstructural analysis, and RSM-based modelling

The development of self-compacting concrete (SCC) has revolutionized modern infrastructure by facilitating the construction of high-strength and intricate structures such as rigid pavements, bridges, tunnels, and skyscrapers since it has superior flowability and capacity for self-consolidation without external vibratio...

Reliability-Based Assessment of Ballast Bearing Capacity Under Aggregate Degradation in Railway Tracks

The long-term performance and safety of ballasted railway tracks are significantly influenced by ballast degradation, which occurs under repeated train axle loads and results in diminished particle angularity, eroded surface texture, increased fines content, and reduced bearing capacity. This study assesses the effects...
