摘要
Currently of global warming, of the critical state of natural resources and of a growing number of endangered species is to get the attention on the specific method of environmental protection. Those methods include the LCA analysis, which has together with waste policy the same center of interest - the preservation of the environment in the sufficient quality for future generations. The basic tool for achieving the objectives is to reduce the environmental and health impacts of waste through their use as alternative substitutes for non-renewable resources. Fly ash, waste of heat generation and of electricity industry is one of the recoverable residues resulting from the burning of coal and it is known as secondary raw material used primarily in the construction industry. As part of ongoing research at the faculty has been studied its 15% wt. cement CEM I 42.5 N replacements in the concrete road cover. The actual contribution is focused on the final stage of research, i.e. to assess of the environmental impact of fly ash concrete pavement throughout their life cycle.
