In the Czech Republic in this connection the development during last ten years was oriented in increased extend on cold in-place recycling techniques. Certain positive potential of this group of techniques is the possibility to use energetic by-products in a form of alternative binders or fillers. These by-products, coming from coal combustion, have a relatively broad range of possible applications especially like alternative substitutes of normally used hydraulic binders (cement, lime) in cold recycling mixes. Within the experimental activities of Faculty of Civil Engineering CTU in Prague cement was replaced by fly-ashes or inorganic loose binder obtained by mechanical activation of fly-ash coming from fluid combustion. For assessed mixes basic volumetric properties, as well as strength and deformation characteristics were determined. Within the evaluation of particular performance characteristics the influence of different aggregate grading on strength properties was assessed as well. From the expected use leaching tests were done for selected mixes as well as combined water and frost susceptibility tested. So far gained results are presented in the paper."@en . . . .
