Recycling of asphalt mixtures - variability of RAP - parameters
Tuháček, Martin ; Koudelka, Tomáš (referee) ; Varaus, Michal (advisor)
The bachelor thesis is focused on RAP material (Reclaimed asphalt pavement), particularly on its characteristics and usage while producing hot mix asphalt at plant. The theoretical part thoroughly describes different fields of application of RAP, these include both the hot and cold recycling. The practical part, on the other hand, essentially covers the problem of using the maximum feasible amount of RAP in hot mix asphalt mixtures; mechanical and psychical properties of a binder and aggregate grading curves are evaluated. On the basis of the testing results, the classification of RAP is undertaken. Moreover, the variability of RAP characteristics is assessed and compared within two various plants. Therefore, the maximum amount of RAP added is based on the very deviation of each characteristic. Representative samples were of two sizes – 0/11 and 0/22.

Usage of of common reclaimed asphalt in asphalt mixtures
Přívara, Jakub ; Coufalíková, Iva (referee) ; Dašek, Ondřej (advisor)
The bachelor thesis is focused on adding of RAP (reclaimed asphalt pavement) to the wearing asphalt courses flexible pavements. Specifically it is SMA 11S asphalt mixture. The theoretical part describes issues of ecology and recycling. The practical part deals with bitumen recovery from SMA mixtures with different added ratios of RAP and assessment of basic empirical and functional tests on the bituminous binder. The verification of properities of modified bituminous binder used in this quality SMA mixtures is also introduced.
