Experimental and analytical investigation of concrete properties made with recycled coarse aggregate and bottom ashInnovative Infrastructure Solutions - Tập 8 - Trang 1-18 - 2023
Ashray Saxena, S. S. Sulaiman, M. Shariq, M. A. Ansari
The present study investigates the rebound hammer number (RHN), ultrasonic pulse velocity (UPV), compressive strength, split tensile strength, and modulus of elasticity of concrete made with recycled coarse aggregate and bottom ash. The natural coarse aggregates (crushed rock aggregates) and fine aggregates (sand) are partially or fully replaced (0%, 50%, and 100%) with recycled coarse aggregates ...... hiện toàn bộ
Development of a flexible pavement design catalogue based on mechanistic–empirical pavement design approach: Egyptian case studyInnovative Infrastructure Solutions - Tập 6 - Trang 1-18 - 2021
Maram Saudy, Tamer Breakah, Sherif El-Badawy, Safwan Khedr
In many regions around the world, the empirical pavement design methods are the only pavement design choices available to pavement engineers. These empirical methods have several limitations. The Mechanistic–Empirical Pavement Design Guide (MEPDG) is the latest pavement design approach and is considered an advanced tool to provide a reliable and economic design. Due to its sophisticated and comple...... hiện toàn bộ
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

Load–settlement response of shallow foundations resting on granular soilInnovative Infrastructure Solutions - Tập 2 - Trang 1-11 - 2017
Mohamed Nimeri, Sherif Elfass, Gary Norris
Proper estimation of settlement of shallow foundations resting on granular soil deposits has a significant role in the design and construction of buildings and other related structures. While several procedures are available in the literature, discrepancies still exist between the predicted and observed responses. Furthermore, there is a decoupling between bearing capacity and settlement assessmen...... hiện toàn bộ
Solidification/stabilization of copper-contaminated soil using magnesia-activated blast furnace slagInnovative Infrastructure Solutions - Tập 8 - Trang 1-11 - 2023
A. Sandeep Reddy, Rama Vara Prasad Chavali
The effluents discharging from various industrial and anthropogenic activities may contain traces of heavy metals. In most countries, these effluents are being disposed into landfills or on the open lands or into nearby water bodies without any prior treatment which may lead to the leaching of heavy metals into the subsurface and causing heavy metal contamination in soils endangering humans and ne...... hiện toàn bộ
Effect of geogrid reinforcement on flexible pavementsInnovative Infrastructure Solutions - Tập 2 - Trang 1-15 - 2017
E. M. Ibrahim, S. M. El-Badawy, M. H. Ibrahim, A. Gabr, A. Azam
Effectiveness of geogrids in flexible pavement reinforcement was investigated throughout laboratory testing and finite-element analysis (FEA). The laboratory testing involved routine material characterization, resilient modulus testing, and five pavement prototype sections. These sections consisted of a 5 cm asphalt concrete (AC) layer, 15 cm granular base layer, and a 30 cm clay subgrade. The bas...... hiện toàn bộ
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
