The most common ways of milled asphalt re-use, what is formed during road topping repair is considered. The results of experimental studies of preparation technology features and physical and mechanical properties of recycled hot mix asphalt determination based on milled asphalt with plastic fiber addition that obtained from industrial waste is presented. Defined regulations correspondence obtained recycled hot mix asphalt and ways of their use in road construction is determined.

Complex comparative analysis of building energy performance rates in EU countries and Ukraine has been carried out.The relation between building insulation rates and European countries climate condition has been investigated. It is illustratedthat there is a significant gap between building energy efficiency characteristics in Ukraine and in most of the EU countries.Economically justified rates of building envelope heat exchange resistance which can lead Ukraine to common Europeanlevel based on optimized calculations are suggested. The necessity for further increase in building envelope heat exchange resistancerates in order to raise building energy efficiency and put Ukrainian building regulations in harmony with EU countriescorresponding norms is proved.
