Možnosti mísení pojiv typu PMB RC s pojivem z R-materiálu / Possibility of mixing PMB RC type binders with reclaimed binder from RAPTrnka, Lukáš Unknown Date (has links)
The diploma thesis deals with the possibility of mixing binders of the PMB RC type with a binder made of reclaimed ashalt. lists the types of asphalt binders, its production and modification are in the teoretical part. There is explained the principle of rejuvenators function, types of rejuvenators. The procedures for performing tests on asphalt binders: recovery of asphalt binder, needle penetration, softening point (ring and ball method), reversible ductility, breaking point (according to Fraass) and DSR. Individual tests are evaluated and asphalt mixtures are compared in the practical part of asphalt binder.

Využití R-materiálu v asfaltových směsích s pojivem typu PMB / Use of R-material in asphalt mixtures with PMB type binderNavrátilová, Pavlína Unknown Date (has links)
The diploma thesis is focused on the use of R-material in asphalt mixtures with a PMB type binder. The work is divided into a theoretical part and a practical part. The theoretical part describes the acquisition of R-material by road milling, the use of R-material, the binder used in the practical part of the work and the types of recycling. The practical part deals with the design of four types of asphalt mixtures with different content of R-material in the asphalt mixture. It also deals with the description of functional tests of asphalt mixtures and the results of these tests.

Dávkování oživovacích přísad do asfaltové směsi s vysokým obsahem R-materiálu / Dosage of rejuvenating agents to asphalt mixture with high content of RAPČumíčková, Markéta January 2019 (has links)
The diploma thesis is focused on the appropriate dosage of rejuvenating agents in asphalt mixtures with high content of RAP. The empirical and functional laboratory tests are described in the theoretical part. The practical part deals with the estimation of the optimal amount of rejuvenating agents by means of laboratory tests so that the rheological properties of the degraded asphalt binder can be restored by suitable dosing into the RAP. As part of the TAČR ZÉTA project, an experimental section of asphalt mixture containing 50 % of the RAP and an appropriate amount of the rejuvenating agents was created. The aim of the thesis is to find an optimal dosage of the rejuvenating agents in the samples of the RAP and laboratory aged asphalt binder of gradation 50/70, to determine the effectiveness of selected rejuvenating agents and to monitor changes in the parameters of the experimental section during the period of time.

Využití R - materiálu v asfaltových kobercích mastixových / Usage of recycled material in stone mastic asphaltsSlavíček, Michal January 2017 (has links)
This diploma thesis deals with the designs of asphalt mixtures for the wearing asphalt courses, specifically for the SMA 11S with an added 30 % and 50 % RAP (reclaimed asphalt pavement), this material was reclaimed from the wearing asphalt course type SMA. The thesis is divided into two parts. The first part is theoretical and it deals with the recycling of asphalt roads and adding RAP to the new asphalt mixures for the roads. The second part is practical. It deals with the design itself. Two types of SMA were designed, first with a 30 % RAP and second with a 50 % RAP. In those mixtures functional tests of asphalt mixtures were made.The results were compared to the asphalt mixture with 0 % of RAP and with the mixture with 30 % of RAP reclaimed from the wearing, binder and base course together. The results are summed up in the conclusion.

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.
