Recyklace stavebních a demoličních odpadů s důrazem na recyklaci silnic

Abstract

Bachelor thesis is focused on the ways of recycling construction and demolition waste, with an emphasis on recycling of roadways. The current growing load of transport infrastructures is the reason for the search for new technologies to increase the quality of structural layers, to reduce costs and to speed up the construction or reconstruction of the roadway. The beginning of the work is dedicated to the characteristics of the construction waste itself and the construction waste from the roadway following the valid legislation. The first part of the text is devoted to the structural layers, their composition and the required thickness according to individual types of roadways. The main causes of failures and suggestions for their removal are described. The next section explains the positive use of R-materials in practice, as well as their processing technology. The last part compares particular technologies of cold and heat recycling and describes their advantages and disadvantages. The conclusion brings the evaluation of lessons learned.
