Modeling of the effect of gradation and compaction characteristics on the california bearing ratio of granular materials for subbase and landfill liner construction [PDF]

Scientific Reports
The California bearing ratio (CBR) of a granular materials are influence by the soil particle distribution indices such as D10, D30, D50, and D60 and also the compaction properties such as the maximum dry density (MDD) and the optimum moisture content ...

Mechanical and Economic Evaluation of Recycled Concrete Aggregate as Granular Road Base and Subbase Material

Journal of Materials in Civil Engineering, 2023
In this study, the usability of recycled concrete aggregates (RCAs) together with crushed aggregate (CA) in granular road base (GRB) and granular road subbase (GRSB) layers was investigated. Three different RCAs as RCA1, RCA2, and RCA3 were used according to their parent concrete compressive strength.

Evaluation of horizontal permeability characteristics of granular subbase material

Transportation Research Procedia, 2020
Abstract Moisture enters into the pavement structure from the surface by infiltrating through cracks and joints, laterally from shoulders, and as capillary suction from bottom. One of the predominant causes for the accumulation of moisture in the pavement structure is inadequate subbase permeability.

Mechanical and Environmental Analysis of Granular Subbase with Fine Crumb Rubber

Arabian Journal for Science and Engineering
AbstractThe increasing manufacturing of tires, driven by the automotive sector, has led to various sustainability and waste management issues. Consequently, it is necessary to explore alternatives for the reuse of these wastes. Rubber has demonstrated properties that could make it an attractive material for use as a granular aggregate.

Medium-size triaxial apparatus for unsaturated granular subbase course materials

Soils and Foundations, 2014
AbstractThis paper proposes a testing method for evaluating the effect of water content on the deformation–strength characteristics of unsaturated subbase course materials. A medium-size triaxial apparatus for unsaturated soils is newly developed in order to examine the mechanical behavior of unsaturated subbase course materials subjected to ...

Variación de la resistencia de una subbase granular debido a la variación del contenido de finos plásticos en granulometrías controladas

Infraestructura Vial, 2014
Los pavimentos sufren deterioros en su capa de rodamiento debido a las cargas y condiciones climáticas a las que se someten. Las características y el estado de las capas inferiores (base, subbase y subrasante) también influyen en el desempeño de la ...
