| Description
| - Presently the focus in road construction sector concentrates on technologies and techniques, which allow decreasing energy demand necessary for their production. At the same time attention is paid to decreasing construction costs related to new structures or pavement rehabilitation works. 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 posibility to use so called energetic by-products in a form of alternative binders or fillers (fine graded particles). These by-products, coming from coal combustion, have a relatively broad range of possible applications especially like alternative substitution of normally used hydraulic binders (cement, lime) in cold recycling mixes. Within the experimental activities of Faculty of Civil Engineering CTU in Prague commonly used cement was replaced by fly-ashes or inorganic loose binder obtained by mechanical activation of fluidized fly-ash. With respect to limited knowledge of behavior and properties of mixes if an alternative material is used, it is necessary to specify correctly newly designed mixes. 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. Some of so far gained results are presented in the paper.
