Recycled Concrete Aggregate is a material resulting from the crushing of concrete elements. Currently, as a result of increased demand for natural aggregates, artificial aggregates are sought as an alternative materials in civil engineering activities. Recycled Concrete Aggregate characterizes high strength, but some properties, both mechanical and physical, remains unclear, which often discourages engineers to use this material. The paper presents the results of the California Bearing Ratio (CBR) and cyclic CBR (...

Since the dawn of time, housing has been closely linked to the characteristic natural environmental factors ? geological, hydrological and climatic conditions occurring in a given area. Lack of knowledge acquired by our ancestors about the causes of processes and phenomena existence in both ? natural and built environment, has led to the formulation of various hypotheses around this subject. One of them became the founding of the art that was focused on finding the right place to settle down permanently (mineral a...

Construction and Demolition (C&D) materials which consists mostly of concrete debris were deposited on landfills. The development of road network results in an increasing demand for building aggregates which are part of the road construction unbound subbase. For decrease of investment costs and prevention of spoiling natural resources, the C&D materials, such as fly ash, steel slag or recycled concrete aggregates (RCA), were applied as a subbase mix. Among many properties influencing the quality of road material, ...
