Fatigue life analysis of steel–concrete composite bridge considering road surface conditionsInnovative Infrastructure Solutions - Tập 7 - Trang 1-10 - 2021
Utkarsha Bhetuwal, Jagat Kumar Shrestha, Rojee Pradhananga
Road surface roughness affects the dynamic interaction between vehicle and bridge. Dynamic impact in the bridge due to vehicle is more if the road surface condition in the bridge is poor. This paper presents a detailed analysis of a composite steel–concrete bridge for its fatigue life due to road surface conditions. The analysis includes a model that takes into account the dynamic impact of vehicl...... hiện toàn bộ
Comparison of different rheological parameters for rutting susceptibility of SBS + WMA modified bindersInnovative Infrastructure Solutions - Tập 1 - Trang 1-10 - 2016
Dharamveer Singh, Aniket V. Kataware
It is important to understand rutting susceptibility of asphalt binders at laboratory scale to ensure a long lasting pavement. Researchers have reported applicability of four rheological parameters: (1) Superpave parameter—G*/sinδ (2) Shenoy’s parameter—G*/(1−(1/tanδsinδ)), (3) non-recoverable creep compliance—J

The impact of using natural waste biopolymer cement on the properties of traditional/fibrous concreteInnovative Infrastructure Solutions - Tập 8 - Trang 1-14 - 2023
Sameh Yehia, Arafa M. Ibrahim, Doaa F. Ahmed
The naturally occurring wastes contain a large number of active groups. In this study, shrimp shell wastes were modified chemically to form chitosan. When mixing concrete with a natural polymer the result revealed a synergistic impact on the characteristics and functionality of the concrete structure. The formed chitosan was characterized by Fourier-Transform Infrared Spectroscopy (FT-IR), Thermog...... hiện toàn bộ
A detailed laboratory investigation on evolving the mix design of roller compacted concrete containing RAP aggregates and SCMsInnovative Infrastructure Solutions - Tập 8 - Trang 1-15 - 2023
Pranav Sharma, Shashi Kant Sharma, Dadi Rambabu, Basireddy Sai Prathap Reddy
Roller compacted concrete (RCC) is a zero-slump concrete designed for dams and low traffic pavements like parking lots, yards, storage areas etc. The constituents of RCC are similar to conventional concrete but aggregate content is higher, about 10% by volume. Due to the scarcity of natural aggregates, recycled asphalt pavement aggregates (RAP) are used to replace partially or fully the natural ag...... hiện toàn bộ
High resolution satellite multi-temporal interferometry for monitoring infrastructure instability hazardsInnovative Infrastructure Solutions - Tập 2 - Trang 1-9 - 2017
Janusz Wasowski, Fabio Bovenga, Raffaele Nutricato, Davide Oscar Nitti, Maria Teresa Chiaradia
Advanced remote sensing techniques are now capable of delivering more rapidly high quality information that is sufficiently detailed (and cost-effective) for many engineering applications. Here we focus on synthetic aperture radar (SAR), multi-temporal interferometry (MTI). With radar satellites periodically re-visiting the same area, MTI provides information on distance changes between the on-boa...... hiện toàn bộ
