Using Reclaimed Asphalt Pavement in High Modulus Asphalt Mixture for Binder Asphalt Courses
Klimek, Matěj ; Hýzl, Petr (referee) ; Šperka, Pavel (advisor)
The bachelor thesis deals with design of high modulus asphalt mixture with using 30 % reclaimed asphalt pavement in combination with polymer modified bitumen. The goal of this thesis is to verify if the mixture reaches the requirements of technical regulations TP 151 [1]. Selected tests were performer in accordance with the European standards ČSN EN 12697 Bituminous mixtures – Test methods for hot asphalt mixtures. Theoretical part of my thesis is focused on possibilities of addition higher amounts of reclaimed asphalt pavement into asphalt mixtures.

Bituminous mixtures with a higher lifetime using recycled asphalt
Stromecký, Roman ; Musil, Vladimír (referee) ; Kudrna, Jan (advisor)
This diploma thesis deals with a project of asphalt mixtures with high stiffness modulus using R-material. The theoretical part describes the characteristics of these mixtures in the Czech Republic and in Switzerland. Further this part deals with the use of R-material in the Czech Republic and chosen other countries of the world, it also deals with the ways of recycling roads. The theoretical part also deals with the testing methods used. In the practical part two new asphalt mixtures of the high stiffness modulus type with the addition of 25 % R-material are suggested. As a base for these two mixtures a mixture of the high stiffness modulus type, which was taken from an asphalt mixing plant, was used. Tests were run on the binders and several functional tests (stiffness modulus, fatigue resistance, low temperature qualities) wer done on the suggested asphalt mixtures and also the mixture taken from the mixing plant. Consequently, the results were compared. The conclusion of the thesis is devoted to modelling a construction of a road using the program LayEps, which verified if the suggested mixtures could reduce the thickness of roads.

Effect of the use of dispersed fibres on the properties of asphalt mixtures
Provazník, Petr ; Bohuš, Štěpán (referee) ; Šperka, Pavel (advisor)
Diploma thesis deals with the topic of using dispersed glass fibers in asphalt mixtures. The theoretical part describes the general properties of glass fibres, their production and use. It also describe issue of dispersed fibers which are currently used as an additive in asphalt mixtures. The practical part deals with behaviour of asphalt mixture which contains dispersed glass fibers. For that reason several test sets with different glass fibre dosages were made. Then individual properties of these test sets were compared with a reference mixture without fibres. The workability of the glass fibres in the asphalt mixture was assessed and after that selected laboratory tests were performed on the produced asphalt mixture namely: water resistence (ITSR), stiffness, wheel tracking, resistence to fatigue.
