The utilization of the pavement waste materials to roads
Furdaničová, Alice ; Šperka, Pavel (referee) ; Stehlík, Dušan (advisor)
The diploma thesis deals with the use of recycled asphalt with aggregate in a hydraulically bound mixtures. The mixture is determined in the base or sub-base course of the pavement. The theoretical part of the diploma thesis describes the base course of the pavement, the production of recyclates from construction demolition waste, the acquisition and processing of recycled asphalt, the road reuse and recycling. The thesis is enriched by a contribution from the implementation of recycled asphalt laying into the base course of the communication company SKANSKA a.s. and ČNES a.s. The next chapter describes detailed experiences with recycling abroad. The thesis also contains a description of laboratory tests, which are important for evaluating the properties of mixtures with recycled asphalt. The practical part verifies the suitability of the mixture of recycled asphalt and aggregate for the road surface by testing the transverse tensile strength, compressive strength and frost and water resistance. The mixtures used are found to be suitable for pavement base course.

Unbound and bound mixtures from recycled concrete of highway D1
Mikulíková, Petra ; Mondschein,, Petr (referee) ; Stehlík, Dušan (advisor)
The work is divided into two parts. The first part deals with the description of unbound and bound base layers and their comparison. Furthermore is presented the description of the recycled concrete, its properties, production, improvement and issues. International experiences with recycled concrete technology are described as well. The practical part is focused on laboratory testing of concrete recycled material taken from the highway D1. The aim of this part is to determine whether the concrete can be recycled back into unbound or bound base layers and concrete casing.

Resistance to freezing and thawing of hydraulically bound mixtures to roads
Švantner, Lukáš ; Mondschein,, Petr (referee) ; Stehlík, Dušan (advisor)
The theoretical part of this master’s thesis contain comparing the methods of endurance hydraulic bound mixtures of concrete recycles against influence of water and freeze in Czech republic and some other states of The European Union. The practical part is dedicated about laboratory testing concrete recycles with mixtures of binders and its endurance against the water and freeze cycles in Czech republic. In made rollers is compared the strength in pure compression with the strength in pure compression after freezing cycles. From the results of the exams is considered about suitability of using these hydraulic bound mixtures to road construction depending on the kind of use binder, amount of the binder and water. Results of this thesis will be used to revision of national postscript of technological norm ČSN 73 6124-1.

The influence of triaxial deformation of aggregates on properties of concrete
Fójcik, Tomáš ; Kalina, Lukáš (referee) ; Šoukal, František (advisor)
This diploma work takes focus in elastic modulus of unbound granular aggregates, which was determined by repeat load triaxial test and in deformation behaviour of unbound granular aggregates - elastic and plastic deformation. It was examine the propriety of this aggregate for its service as underlying granular material in pavement. Further, there was observed the influence of elastic modulus of unbound granular aggregates on concrete characteristics - compressive and bending strength. Finally, it was observed the influence of individual fractions of aggregates on its elastic modulus and strength of concrete.

Design of boundary conditions for mixtures for road base layers
Holubec, Matěj ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
The bachelor thesis deals with the design of suitable composition of uncompacted mixtures and mixtures cemented with hydraulic binders for road pavement subbase layers. The theoretical part describes the characteristic properties and applications of the tested material. The practical part deals with the determination of the geometric properties of unbound mixtures and mixtures bound with hydraulic binder, which are determined on the basic of laboratory tests.
