The soil under this class was unsuitable for subgrade construction. The qualities of stabilized soil were evaluated using the Atterberg limit, compunction, and CBR test. Crushed stone dust was used to stabilize the soil in stepwise proportions of 0%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, and 50% by dry weight of soil.

Use of recycled concrete aggregate (RCA) as highway basecourse material conserves aggregate, reduces energy consumption and CO 2 emissions, and may also decrease costs during construction. However, concerns remain over possible negative environmental impacts associated with high pH (>11) effluent from RCA in contact with …

Recycled concrete aggregates (RCAs) have a high potential to be used as replacements for natural aggregates in the construction of pavements with similar or even better characteristics. This paper evaluates the influence of RCA as a partial replacement in a granular sub-base of 37.5 mm nominal maximum size (GSB38). Specifically, two …

2.4.2. Atterberg Limits. The Atterberg limits are a basic measure of the nature of a fine-grained soil.Depending on the water content of the soil, it may appear in four states: solid, semi-solid, plastic and liquid. In each state the consistency and behavior of a soil is different and thus so are its engineering properties.
