Determination of the Physical-Mechanical Characteristics of Non-Cohesive Soils Stabilized with Fly Ash (Part II)

The unprecedented scale of road network development programs in our country requires the consumption of materials (natural aggregates, binders), often non-renewable and expensive, which are difficult to secure from traditional sources. Alternative solutions for the replacement of natural aggregates, binders, as viable alternatives to classical technologies, the adoption and continuous development of recycling technologies are concerns of researchers, designers and road builders. So, the stabilized mixtures successfully form the sub-grade layers of the rigid road structures or both the sub-grade layers and the base layers of the semi-rigid structures (Zarojanu, 1976).

Compared to traditional, untreated, thick foundations, the stabilized foundations, consisting of a series of thinner layers (assizes), with considerably increased rigidity, ensure a more judicious distribution of traffic loads for lower overall thicknesses of the road structure (Boboc, 1995).
