RISManufacturing Artificial Aggregates from Overburden Coal Mine Waste and Their Properties for Pavement Applications
Publisher: American Society of Civil Engineers
Abstract: Owing to a severe shortage of natural aggregates in terms of quantity and quality, alternative aggregate resources must be utilized in civil engineering construction to meet significant increase in aggregate demand. This ...
Behavior of Connected and Unconnected Back-to-Back Walls for Bridge Approaches
Publisher: ASCE
Abstract: Back-to-back mechanically stabilized earth (MSE) walls are commonly used in the construction of transportation infrastructure facilities. Federal Highway Administration (FHWA) guidelines discuss briefly the design of ...
Site Characterization of Existing and Abandoned Coal Ash Ponds Using Shear-Wave Velocity from Multichannel Analysis of Surface Waves
Publisher: ASCE
Abstract: Coal ash ponds or lagoons are surface impoundments constructed to store the unused coal ash generated from thermal power plants. In India, by the end of 2020 nearly 82,200 ha of land will be under ash ponds. Once the ...
Development of a Unique Test Apparatus to Conduct Axial and Transverse Pullout Testing on Geogrid Reinforcements
Publisher: ASCE
Abstract: In the design of reinforced soil structures, the pullout resistance of reinforcement embedded in the fill material is an important input parameter. Different pullout test setups have been proposed previously to determine ...
Modulus Improvement Factor-Based Design Coefficients for Geogrid- and Geocell-Reinforced Bases
Publisher: ASCE
Abstract: A series of large-scale model experiments were carried out on different geogrid- and geocell-reinforced base courses to evaluate realistic base-layer coefficients to design flexible pavements. The placement depth of ...
Application of Machine-Learning Algorithms for Predicting California Bearing Ratio of Soil
Publisher: ASCE
Abstract: Subgrade strength is characterized by many indices such as the California bearing ratio, resilient modulus, and dynamic modulus. The California bearing ratio (CBR) of the subgrade soil is an important input parameter in ...
Strength-Gain Characteristics and Swelling Response of Steel Slag and Steel Slag–Fly Ash Mixtures
Publisher: ASCE
Abstract: The shear strength and stiffness characteristics of steel slag indicate that it can potentially be utilized as a competent base/subbase material of bound and unbound pavement layers. However, concerns with respect to the ...
Interface Shear Stress Properties of Geogrids with Mixtures of Fly Ash and Granulated Rubber
Publisher: ASCE
Abstract: In recent times, alternative ways to dispose various wastes generated, namely, fly ash, scrap tires, steel or iron slag, and foundry sand, are on the rise. Owing to low unit weight and good hydraulic conductivity properties ...
Optimum Mixing Ratio and Shear Strength of Granulated Rubber–Fly Ash Mixtures
Publisher: American Society of Civil Engineers
Abstract: Studies on shredded waste tires mixed with sand for fill applications are well documented. In this study, a new composite material from mixture of shredded tires and fly ash as fill material is explored. Shredded waste ...
