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

Sci Rep
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 (OMC).

Granular Subbase Improvement with Recycled Concrete Aggregates in Tropical Areas

IIUM Engineering Journal, 2022
Use of Recycled Concrete Aggregate (RCA) for Granular Subbase (GSB) in the tropical area is evaluated in this work. Among the materials widely studied as replacements in granular and surface layers is RCA. Its mechanical behavior in granular layers has mainly been evaluated with tests such as California Bearing Ratio (CBR).

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.

Determination of the Adequate Thickness of Granular Subbase Beneath Foundations [PDF]

Engineering and Technology Journal, 2011
Where the native soils have poor structural qualities or are expansive, the soil investigation report may recommend importation of soils better suited to providing a subbase for structures. This requires considering two soil layers in bearing capacity calculations.

Improvement in the California bearing ratio of subbase soil by recycled asphalt pavement and cement

Open Engineering, 2023
As the subbase layer is one of the important layers in road construction, it is necessary to use a granular material to resist traffic loads. Usually, granular soil with a good gradation is used, which is determined by most road design codes.

Stabilisation and bearing capacity improvement of granular platform [PDF]

E3S Web of Conferences
Building roads or platforms on weak soil is a remaining challenge. The reduction of granular material required for the subbase is more and more crucial, for cost reasons but also for a much lower impact of the earthworks on the environment. Geosynthetics
