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 ...

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.
