Quality of the recycled aggregates to the roads
Sokolová, Veronika ; Pecha, Karel (referee) ; Stehlík, Dušan (advisor)
Theoretical part of the thesis describes the production, properties and characteristics of recycled aggregates and the resulting assessment of the suitability of its use in the construction of roads. The practical part is focused on implementing the basic tests of aggregates according to applicable standards, such as bulk density, water absorption and resistance to crushing of aggregates. Tests are performed on fractions of the three types of recycled aggregate and then compared with the same results of tests on natural aggregates.

The modification of the cyclic triaxial test
Nevrlá, Alice ; Pecha, Karel (referee) ; Stehlík, Dušan (advisor)
This bachelor's thesis focuses on determining resilient modulus of unbound granular material for subbase and subgrade pavement construction using different types of cyclic load triaxial testing procedures in Czech Republic and abroad and compares them. The practical part then deals with comparison of methods presented in Czech Standard ČSN EN 13286-7 used for resilient modulus determination of mixed recycled material, finegrained soil and fly ash.

The waste buildings material to subgrade of the pavement
Ševc, Jan ; Pecha, Karel (referee) ; Stehlík, Dušan (advisor)
The thesis is focused on the use of waste buildings materials to subgrade of the pavement. In detail it deals with monitoring the carrying capacity of the material used to replace unsuitable subgrade mainly of the urban road communications. It practically verifies California bearing ratio and resistance to frost and water of the waste buildings materials firmed by cement for possible use in subbase layers. The amount of residues in recycled bricks is essential for positive results in terms of the properties of materials in subgrade of the pavement.
