Hodnocení vlastností pojiv typu PMB obsahujících pojivo z R-materiálu / Evaluation of properties of PMB containing binder from RAPMěšťanová, Petra Unknown Date (has links)
Subject of this diploma thesis is to describe the effect of adding different amount of aged binder recovered from RAP on the change of properties of polymer modified bitumen. The RAP containing unmodified bitumen and the RAP where we can expect bitumen modification are used to recover binder. The binder obtained from RAP is dosed into the virgin binder in amount of 15 %, 30 % and 50 %. The methods of recycling of flexible pavements, extraction and regeneration of asphalt binders, rejuvenating of their properties and methods of empirical and functional laboratory tests are described in the theoretical part. The practical part deals with evaluating and comparison of the results mixed binders properties.

Problematika testování stříkaných betonů / The Issue of testing shotcreteŠkapová, Pavla January 2014 (has links)
The master‘s thesis focuses on testing the shotcrete prepared in laboratory conditions. The main observed properties are compresive strenght of shotcrete and modulus of elasticity. The aim is assessment of methods for measuring those parameters. The calibrating correlations for strenght characteristics of shotcrete are given by obtaining the results of used methods. The shotcrete composition, amount and type of accelerating additive as well as economic aspect of using shotcrete is also assessed.
