Railway noise has become a significant concern for trackside residents due to increased volume of high-speed passenger and freight train traffic. To address this, active measures, such as reducing noise at the source, and passive measures, such as installing noise barriers along the transmission path, are widely being used. In urban areas, railway...

The urban environment is characterized by diverse noise sources, which include various modes of transport, industrial activities, household disturbances, and recreational activities. This collective soundscape in an urban setting is recognized as an emerging environmental concern. Particularly, transportation noise often exceeds the recommended gui...

Every ambient noise study employs the source-path-receiver structure to explore the overall behaviour of sound. Noise levels are affected by changes in distance, intervening barriers, and atmospheric conditions along the transmission path between the source and the receiver. The objective of this study is to quantify the influence of transmission p...

Urban expansion and infrastructure development have exacerbated environmental issues by creating impermeable layers on the earth's surface, resulting in flash floods and reduced groundwater levels. These problems can be alleviated by using pervious concrete to enhance pavement drainage capacities. However, pervious concrete has limited applications...

Pervious concrete has gained research interest due to its eco-friendly system and hydrological benefits. With sustainability in view, several researchers tried to employ alternatives such as Supplementary Cementitious Materials (SCMs) in concrete. However, studies on employing high-volume SCMs as cement replacement in pervious concrete are scanty....

Urban environment noise is a complex mixture of transportation, industrial, household and recreational noise, which is identified as an emerging environmental threat. Present study monitors and evaluates a noise pollution hotspot: a railway level crossing, where several activities related to transportation noise were involved. Train honking, train...

The application of pervious concrete in highway pavements is restricted due to its less compressive strength. Several techniques were identified to increase the strength of the pervious concrete by altering cement to aggregate ratio, utilizing extra cementitious material, changing aggregate size and gradation. The present work is focused on the stu...

In this study, two issues related to the pervious concrete are addressed, and a proper solution is drawn. The first issue is related to strength and the second one is related to permeability. We have used some of the available industrial waste like fly ash, silica fume, and furnace slag in replacement of cement at 20%, 35%, and 50%. The study is co...
