Dynamic Response of Bridges and its Effect on Soil Medium
Abstract: The analysis of dynamic behaviour of bridge structures that are subjected to moving loads has been one of the research benefits in recent years. Specifically in railway bridges, resonance ensues when the load frequency is equal to a multiple of natural frequency of the structure. Resonance vibrations have been practical in railway bridges, especially subjected to high-speed lines. They are caused primarily because of two reasons: one is the repeated …

Effect of Aggregate Shape and Binder on the Rutting Characteristics of Bituminous Mixes
Abstract: Rutting or permanent deformation is the depression in the wheel paths due to accumulation of small amounts of unrecoverable strains under the channelized repeated wheel loads. Shear deformation or lateral plastic flow of the bituminous mix from the wheel tracks also results in rutting. Performance of bituminous mixes is influenced by the constituents of the mix made of aggregates and binder. Among various parameters of these two ingredients, aggregate shape …
