Secondary title:	Cold in-place recycling with fly ash
Secondary abstract:	The first part of the thesis describes layers of pavement structure, exposure and distress of surface layers. Pavements can be maintained either by surface or structural rehabilitation. The main difference is in complexity and financial costs of maintenance. Cold in-place recycling with fly ash is a part of structural rehabilitation. The technology of recycling is produced by the German company Wirtgen. Fly ash is a by-product of coal combustion. Depositing of fly ash must be provided on suitable depots. In present time, usage of fly ash is increasing in road construction. The second part of the thesis describes practical application of fly ash to cold in-place recycling. The case study was the reconstruction of Podrošt – Češnjica road in Železniki municipality. The road was severely damaged in the flood of 2007. Initially, the project predicted that mill and replace of pavement structure would be implemented, but the contractor applied for technology change to cold recycling. In the process, subgrade soil was stabilized with fly ash and granular base was built of milled asphalt. Using new technology, we successfully reduced material consumption and much less newly manufactured material was needed. The thesis also presents preliminary researches of existing pavement, construction procedure and analysis of external supervisor’s report. In conclusion I tried to analyze the economic and environmental aspects of mill and replace of pavement structure and cold in-place recycling; furthermore, I tried to ascertain that cold in-place recycling is more economic and environmentally friendly than mill and replace of pavement structure.
