Prediction of Freezing Temperature inside Concrete Crossties at the Rail Seat Area
(American Society of Civil Engineers, 2019)Air-entrained high performance concrete (HPC) crossties or ties (alternatively called sleepers outside of North America) have been observed to suffer structural and material degradation at the rail seat area (RSA), including ... -
Development of Hybrid Material as Drainage Media and Efficiency Comparison of Various Vertical Drains
(American Society of Civil Engineers, 2019)Vertical drains are extensively used for ground improvement in order to accelerate the consolidation settlement of soft clay deposits. In the case of very soft clay, if sand/aggregate alone is provided, the diameter of the ... -
Influence of Warm-Mix Additives on Physical, Rheological, and Morphological Properties of High-Viscosity Asphalt
